Abstract
Electrocatalytic carbon dioxide reduction reaction (CO2RR) generates high value-added products and simultaneously reduces excess atmospheric CO2 concentrations, is regarded as a potential approach to achieve carbon neutrality. However, the kinetic process of the anode oxygen evolution reaction (OER) is slow, resulting in a poor electrochemical efficiency of CO2RR. It is a breakthrough to replace OER with methanol oxidation reaction (MOR), which has more advantageous reaction kinetics. Herein, this work proposed a bifunctional catalyst Bi2O3-SnO modified CuO nanowires (Bi2O3-SnO@CuO NWs) with excellent CO2RR and MOR performance. For CO2RR, Bi2O3-SnO@CuO NWs achieved more than 90% formate selectivity at wide potential windows from -0.88 to -1.08 V (vs. reversible hydrogen electrode (RHE)), peaking at 96.6%. Meanwhile, anodic Bi2O3-SnO@CuO NWs achieved 100 mA cm-2 at a low potential of 1.53 V (vs. RHE), possessing nearly 100% formate selectivity ranging from 1.6 to 1.8 V (vs. RHE). Impressively, by coupling cathodic CO2RR and anodic MOR, the integrated electrolytic cell realized co-production of formate (cathode: 94.7% and anode: 97.5%), minimizing the energy input by approximately 69%, compared with CO2RR. This work provided a meaningful perspective for the design of bifunctional catalysts and coupling reaction systems in CO2RR.

Abstract
Crystalline porous materials sustained by supramolecular interactions (e.g., π-π stacking interactions) are a type of molecular crystals showing considerable stability, but their applications are rarely reported due to the high difficulty of their construction. Herein, a stable π-π stacking framework formed by a trinuclear copper(I) compound [Cu3(HBtz)3(Btz)Cl2] (CuBtz, HBtz = benzotriazole) with pyrazolate-bridged dicopper(I) sites is reported and employed for electrochemical CO2 reduction, showing an impressive performance of 73.7 ± 2.8% Faradaic efficiency for C2+ products [i.e., ethylene (44%), ethanol (21%), acetate (4.7%), and propanol (4%)] with a current density of 7.9 mA cm-2 at the potential of -1.3 V versus RHE in an H-type cell and a Faradic efficiency (61.6%) of C2+ products with a current density of ≈1 A cm-2 and a reaction rate of 5639 μmol m-2 s-1 at the potential of -1.6 V versus RHE in a flow cell device, representing an impressive performance reported to date. In-situ infrared spectroscopy, density functional theory calculations, and control experiments revealed that the uncoordinated nitrogen atoms of benzotriazolates in the immediate vicinity can act as proton relays and cooperate with the dicopper(I) site to promote the hydrogenation process of the *CO intermediate and the C-C coupling, resulting in the highly selective electroreduction of CO2 to C2+ products.

Abstract
The self-assembly of metal–organic frameworks (MOFs) is crucial for the functional design of materials, including energy storage materials, catalysts, selective separation materials and optical crystals. However, oriented self-assembly of MOFs is still a challenge. Herein, we propose a novel strategy to drive oriented self-assembly of MOF polyhedral particles at the water–liquid interface by photoinitiated monomer polymerization. The MOF polyhedral particles self-assemble into ordered close-packed structures with obvious orientation in the polymer film, and the orientation is determined by the casting solvent on the water surface. The prepared large-area MOF polymer films show a Janus structure, containing a MOF monolayer and a polymer layer, and can be easily transferred to a variety of substrates. In addition, mixed MOF particles with different sizes and morphologies can also be assembled by this method. This novel method can be foreseen to provide a powerful driving force for the development of MOF self-assembly and to create more possibilities for utilizing the anisotropic properties of MOFs. The self-assembly of metal–organic frameworks (MOFs) is crucial for the functional design of materials, including energy storage materials, catalysts, selective separation materials and optical crystals.![]()
