Abstract
Herein, the design and synthesis of Ru-doped CoFe-layered double hydroxide (CoFeRu─LDH) nanostructures is presented via an innovative yet straightforward pulsed laser method. The CoFeRu─LDH catalyst demonstrates outstanding electrocatalytic performance, achieving a high NH4 + Faradaic efficiency (FE) of 89.65% at -0.7 V versus reversible hydrogen electrode for nitrite reduction reaction (NO2 -RR) and a low overpotential of 297 mV at 10 mA cm-2 for oxygen evolution reaction (OER). Comprehensive in situ and ex situ analyses reveal the electrochemically energetic species formed on the CoFeRu─LDH surface during the NO2 -RR and OER. Theoretical studies confirm that Ru doping plays an imperative role in tuning the electronic structure of CoFeRu─LDH, lowering its reaction barriers, and thereby remarkably enhancing its NO2 -RR and OER performance. Specifically, a galvanic Zn-nitrite battery using CoFeRu─LDH as the cathode efficiently converts NO2 - to NH4 + with an FE of 96.8% while concurrently generating electricity with a power density of 4.14 mV cm-2. Furthermore, pairing CoFeRu─LDH as the anode with Pt/C as the cathode in water electrolysis enables H2 production at a low cell voltage of 1.57 V at 10 mA cm-2. This study presents a new pathway to designing versatile, high-performance electrocatalysts for sustainable energy conversion and the production of carbon-free NH3 and H2 fuels.

Efficient Electrochemical Co-Reduction of Carbon Dioxide and Nitrate to Urea with High Faradaic Efficiency on Cobalt-Based Dual-Sites. ADVANCED MATERIALS (DEERFIELD BEACH, FLA.) 2024; 36:e2401221. [PMID: 38563723 DOI: 10.1002/adma.202401221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 03/18/2024] [Indexed: 04/04/2024]
Abstract
Renewable electricity-powered nitrate/carbon dioxide co-reduction reaction toward urea production paves an attractive alternative to industrial urea processes and offers a clean on-site approach to closing the global nitrogen cycle. However, its large-scale implantation is severely impeded by challenging C-N coupling and requires electrocatalysts with high activity/selectivity. Here, cobalt-nanoparticles anchored on carbon nanosheet (Co NPs@C) are proposed as a catalyst electrode to boost yield and Faradaic efficiency (FE) toward urea electrosynthesis with enhanced C-N coupling. Such Co NPs@C renders superb urea-producing activity with a high FE reaching 54.3% and a urea yield of 2217.5 µg h-1 mgcat. -1, much superior to the Co NPs and C nanosheet counterparts, and meanwhile shows strong stability. The Co NPs@C affords rich catalytically active sites, fast reactant diffusion, and sufficient catalytic surfaces-electrolyte contacts with favored charge and ion transfer efficiencies. The theoretical calculations reveal that the high-rate formation of *CO and *NH2 intermediates is crucial for facilitating urea synthesis.

High-efficiency electrocatalytic nitrite reduction toward ammonia synthesis on CoP@TiO 2 nanoribbon array. iScience 2023; 26:107100. [PMID: 37426356 PMCID: PMC10329173 DOI: 10.1016/j.isci.2023.107100] [Citation(s) in RCA: 40] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 04/20/2023] [Accepted: 06/08/2023] [Indexed: 07/11/2023] Open
Abstract
Electrochemical reduction of nitrite (NO2-) can satisfy the necessity for NO2- contaminant removal and deliver a sustainable pathway for ammonia (NH3) generation. Its practical application yet requires highly efficient electrocatalysts to boost NH3 yield and Faradaic efficiency (FE). In this study, CoP nanoparticle-decorated TiO2 nanoribbon array on Ti plate (CoP@TiO2/TP) is verified as a high-efficiency electrocatalyst for the selective reduction of NO2- to NH3. When measured in 0.1 M NaOH with NO2-, the freestanding CoP@TiO2/TP electrode delivers a large NH3 yield of 849.57 μmol h-1 cm-2 and a high FE of 97.01% with good stability. Remarkably, the subsequently fabricated Zn-NO2- battery achieves a high power density of 1.24 mW cm-2 while delivering a NH3 yield of 714.40 μg h-1 cm-2.
