Abstract
Rational design and synthesis of high-performance electrocatalysts for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) are critical for practical application of Zn-air batteries (ZABs). In this work, the bifunctional composite Cu-Fe2O3/PNC was prepared by a simple and effective wet-hydrothermal coupled dry-annealing synthesis strategy. The Cu-Fe2O3/PNC displayed excellent catalytic activity in ORR and OER with a potential difference of 0.63 V. More importantly, the ZAB assembled with Cu-Fe2O3/PNC exhibited a high-power density of 138.00 mW cm-2 and an excellent long-term cyclability. X-ray photoelectron spectroscopy (XPS) demonstrated that the excellent performance is due to the strong electronic interaction between Cu and Fe2O3 that arises as a result of the fast electron transfer through the Cu-O-Fe bond and the higher concentration of surface oxygen vacancies. Meanwhile, the spillover factor Bsp/2zF of Cu/PNC and Cu-Fe2O3/PNC obtained by the rotating disk experiment was 1.00 × 10-7 and 1.10 × 10-7 cm2·s-1, respectively, indicating that the oxygen spillover effect between Cu and Fe2O3 lowers the energy barrier, increases the number of active sites, and alters the rate-determining reaction step. This work demonstrated the significant potential of Cu-Fe2O3/PNC in energy conversion and storage applications, providing a new perspective for the rational design of bifunctional electrocatalysts.

Abstract
The catalytic hydrogenolysis of lignin has been reported as an effective approach for lignin depolymerization owing to its high efficiency for aromatic monomer production. In this study, a series of copper monometallic catalysts over an MIL-101(Cr) support were synthesized and used for the catalytic hydrogenolysis of alkali lignin using supercritical ethanol. First, the optimal copper catalyst for lignin hydrogenolysis was selected. Subsequently, the reaction conditions for catalytic hydrogenolysis were systematically optimized to maximize the total monomer yield. The optimal conditions were determined to be 6 h of reaction time, 20 min of sonication pretreatment, 50% catalyst loading, and 5% lignin loading. Under these conditions, an aromatic monomer yield of 38.5% was obtained; this depolymerized lignin stream, which is mainly composed of G-type monomers, can serve as a promising aromatic feedstock and carbon source for further microbial upgrading and bioconversion to produce various value-added products.

Abstract
In the present study, the carbon monoxide (CO) sensing property of Cu(II)-l-aspartic acid nanofibers/polyaniline (PANI) nanofibers composite was investigated at room temperature. The nanofiber composite was formed through the ultrasound mixing of emeraldine salt PANI nanofibers and Cu(II)-l-aspartic acid nanofibers, which were synthesized by using a polymerization process and simple self-assembly method, respectively. The nanofibers composite demonstrated a branched structure in which the Cu(II)-l-aspartic acid nanofiber framework is similar to the trunk of a tree and the polyaniline nanofibers is like its branches. It seems that this special structure and one-dimension/one-dimension interface are suitable for gas adsorption and sensing. The performance of the prepared sensor toward CO gas was investigated at room temperature in a wide concentration range (200-8000 ppm). The experimental results indicate that the incorporation of amino acid-based copper metal-biomolecule framework nanofibers to PANI nanofibers enhances the response value (12.41% to 4000 ppm), yielding good selectivity and acceptable response and recovery characteristics (220 s/240 s) at room temperature. The detection limit of Cu(II)-l-aspartic acid nanofibers/PANI nanofibers sensor for carbon monoxide is obtained at 120 ppm.

Abstract
Carbon nanospheres integrated with AuNPs and amorphous Co3O4 were fabricated by making use of cobalt coordination with AuNP surface ligands, which exhibited an enhanced oxygen evolution reaction (OER) with excellent mass activity. Co2+ coordination with AuNP surface functional molecules significantly influenced the nanostructure formation and OER activity. Nanospheres of carbon with an optimum concentration of AuNPs and Co3O4 (2) showed strong OER activity. 2 exhibited a high current density (358 mA cm-2 at an applied potential of 1.59 V) and required a low overpotential (256 mV) to generate a geometric current density (10 mA cm-2) compared to commercial RuO2 (363 mV). Importantly, 2 showed high mass activity (1352.5 mA mg-1), 14 times higher than RuO2 (93.87 mA mg-1). The low Tafel slope (52.4 mV dec-1) and charge transfer resistance along with large double layer capacitance (Cdl = 20.1) of 2 suggest strong electronic communication between the catalyst and the electrode surface and facilitated fast charge transport. Chronoamperometric studies confirmed the excellent stability of the catalyst. The present work demonstrates that the electrocatalytic activity of earth-abundant amorphous metal oxides can be strongly enhanced by integrating metallic nanoparticles (NPs) and optimizing nanostructures.

Abstract
Electrocatalysis for nitrate reduction reaction (NRR) has recently been recognized as a promising technology to convert nitrate to nitrogen. Catalyst support plays an important role in electrocatalytic process. Although porous carbon and metal oxides are considered as common supports for metal-based catalysts, fabrication of such architecture with high electric conductivity, uniform dispersion of nanoparticles, and long-term catalytic stability through a simple and feasible approach still remains a significant challenge. Herein, inspired by the signal transfer mode of dendritic cell, an all-carbon dendritic cell-like (DCL) architecture comprising mesoporous carbon spheres (MCS) connected by tethered carbon nanotubes (CNTs) with CuPd nanoparticles dispersed throughout (CuPd@DCL-MCS/CNTs) is reported. An impressive removal capacity as high as 22 500 mg N g-1 CuPd (≈12 times superior to Fe-based catalysts), high nitrate conversion (>95%) and nitrogen selectivity (>95%) are achieved under a low initial concentration of nitrate (100 mg L-1 ) when using an optimized-NRR electrocatalyst (4CuPd@DCL-MCS/CNTs). Remarkably, nitrate conversion and nitrogen selectivity are both close to 100% in an ultralow concentration of 10 mg L-1 , meeting drinking water standard. The present work not only provides high electrocatalytic performance for NRR but also introduces new inspiration for the preparation of other DCL-based architectures.

SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2019; 15:e1804268. [PMID: 30650234 DOI: 10.1002/smll.201804268] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2018] [Revised: 12/01/2018] [Indexed: 06/09/2023]
Abstract
Developing earth-abundant electrocatalysts for high-efficiency hydrogen evolution reaction (HER) has become one of the leading research frontiers in energy conversion. Here, the design and in situ growth of Ag nanodots decorated Cu2 O porous nanobelts networks on Cu foam (denoted as Ag@Cu2 O/CF) are carried out via a simple one-pot solution strategy at room temperature. Serving as self-supporting electrocatalysts, Ag@Cu2 O porous nanobelts provide plentiful active sites, and the 3D hybrid foams provide fast transportation for electrolyte and short diffusion path for newly formed H2 bubbles, which result in excellent electrocatalytic HER activity and long-term stability. Owing to the synergistic effect between Ag nanodots and Cu2 O porous nanobelts and CF, the hybrid electrocatalyst exhibits a low Tafel slope of 58 mV dec-1 , a small overpotential of 108 mV at 10 mA cm-2 , and high durability for more than 20 h at a potential of 200 mV for HER in 1.0 mol L-1 KOH solution.

Abstract
Covalent organic frameworks (COFs) are a new class of porous crystalline polymers with a modular construct that favors functionalization. COF pores can be used to grow nanoparticles (nPs) with dramatic size reduction, stabilize them as dispersions, and provide excellent nP access. Embedding substrate binding sites in COFs can generate host-guest synergy, leading to enhanced catalytic activity. In this report, Cu/Cu2O nPs (2-3 nm) are grown on a COF, which is built by linking a phenolic trialdehyde and a triamine through Schiff bonds. Their micropores restrict the nP to exceptionally small sizes (∼2-3 nm), and the pore walls decorated with strategically positioned hydrogen-bonding phenolic groups anchor the substrates via hydrogen-bonding, whereas the basic pyridyl sites serve as cationic species to stabilize the [CuclusterCl2]2- type reactive intermediates. This composite catalyst shows high activity for Glaser-Hay heterocoupling reactions, an essential 1,3-diyne yielding reaction with widespread applicability in organic synthesis and material science. Despite their broad successes in homocoupled products, preparation of unsymmetrical 1,3-diynes is challenging due to poor selectivity. Here, our COF-based Cu catalyst shows elevated selectivity toward heterocoupling product(s) (Cu nP loading 0.0992 mol %; turn over frequency: ∼45-50; turn over number: ∼175-190). The reversible redox activity at the Cu centers has been demonstrated by carrying out X-ray photoelectron spectroscopy on the frozen reactions, whereas the crucial interactions between the substrates and the binding sites in their optimized configurations have been modeled using density functional theory methods. This report emphasizes the utility of COFs in developing a heterogeneous catalyst for a truly challenging organic heterocoupling reaction.
