Recently, global-scale efforts have been conducted for the electroreduction of CO2 as a potentially beneficial pathway conversion greenhouse gases to useful chemicals and renewable fuels. This study focuses on development selective sustainable electrocatalysts reduction aqueous CO. A RuIIcomplex [Ru(tptz)(ACN)Cl2] (RCMP) (tptz = 2,4,6-tris(2-pyridyl)-1,3,5-triazine, ACN acetonitrile) was prepared molecular electrocatalyst reaction in an solution. Density functional theory-calculated frontier orbitals suggested that tptz ligand plays key role dictating electrocatalytic reactions. The RCMP grafted onto graphene oxide (GO) surface both noncovalently (GO/RCMP) covalently (GO-RCMP). field emission scanning electron microscopy elemental distribution analyses revealed homogeneous complex GO sheet. photoluminescence spectra confirmed accelerated charge-transfer nanohybrids. Compared bare complex, GO-RCMP GO/RCMP nanohybrids showed enhanced activity, achieving >95% 90% Faradaic efficiencies CO production at more positive onset potentials, respectively. nanohybrid demonstrated outstanding activity with current ∼84 μA. offers perspective outer- inner-sphere electron-transfer mechanisms electrochemical energy systems.

Abstract Electrocatalytic carbon dioxide reduction reaction (CO 2 RR) has emerged as a promising and sustainable approach to cut emissions by converting greenhouse gas CO value‐added chemicals fuels. Metal–organic coordination compounds, especially the copper (Cu)‐based which feature well‐defined crystalline structures designable metal active sites, have attracted much research attention in electrocatalytic RR. Herein, recent advances of electrochemical RR on pristine Cu‐based compounds with different types Cu sites are reviewed. First, general pathways briefly introduced. Then highly efficient conversion various kinds (e.g., single‐Cu site, dimeric‐Cu multi‐Cu heterometallic site) is systematically discussed, along corresponding catalytic mechanisms. Finally, some existing challenges potential opportunities for this direction provided guide rational design metal–organic their practical application

Electrochemical reduction of CO2 into high-value-added products is a potential approach to solving environmental problems but limited by poor product selectivity and low efficiency. Metal–organic framework (MOF) materials have been considered one the most promising catalysts, their application complicated preparation processes, especially during synthesis organic ligands. In this work, new three-dimensional Cu-MOF (JXUST-301) with high porosity was constructed based on naphthalene diimide (NDI) ligand. Furthermore, JXUST-301 ligand defects (JXUST-301D) originating from missing NDI unit synthesized via an in situ reaction. The presence endows JXUST-301D better CO2RR performance FEC2 56.7% jC2 −162.4 mA cm–2. Mechanistic studies revealed that hierarchical pore structure amino sites are created absence unit, which promotes exposure catalytically active enrichment. electronic Cu modulated upshift d-band center, facilitating chemical adsorption activation key reaction intermediates. This work provides insight efficient catalysts introducing for CO2RR.
