Electrochemical CO2 reduction offers a promising approach to alleviate environmental and climate impacts attributed to increasing atmospheric CO2. Intensive research work has been performed over the years on catalysts, membranes, and other associated components related to the development of CO2 electrolyzers. Herein, we assembled a full cell comprising a Bi nanoparticle (NP)-based cathode for reducing CO2 to formate and the earth-abundant NiFe layered double hydroxide (LDH)-based anode for oxygen evolution. The electrolyte used was 1 M KOH, and an anion exchange membrane separator was employed...

Abstract The production of new solar fuel through CO photocatalytic reduction has aroused tremendous attention in recent years because of the increased demand of global energy sources and global warming caused by the mass concentration of CO in the earth's atmosphere. In this work, UiO-66-NH was co-modified by the Au nanoparticles (Au-NPs) and Graphene (GR). The resultant nanocomposite exhibits a strong absorption edge in visible light owing to the surface plasmon resonance (SPR) of Au-NPs. More attractively, Au/UiO-66-NH /GR displays much higher photocatalytic activity (49.9 μmol) and se...
