Artificial photosynthesis is a viable technique for mitigating the ever-increasing energy demands by converting carbon dioxide (CO2) into energy-rich C1 and C2+ products. A massive contribution to climate change global warming widespread use of fossil fuels, responsible more than 90% total CO2 emissions 75% greenhouse gas emissions. The most efficient method convert renewable clean utilizing plentiful sun accelerate photo-induced chemical reactions. Practical reduction (CO2R), including choosing promising wide-bandgap (WBG) semiconductor photocatalysts with negative conduction band potential, would be holy grail selective fuels chemicals production. This review article deliberates on importance WBG specific level in photocatalytic CO2R, which may assist guiding future photocatalyst design CO2R. In addition, summary prospects techniques improving conversion efficiency selectivity are discussed.

Comprehensive Summary We present a facile synthetic strategy to create mesoporous Cu 2 O nanocrystals with tunable pore structures and surface functional groups of amine derivatives for efficient preferable electrochemical conversion CO into ethylene. The structural characteristics these can be manipulated using set derivatives, such as pyridine, 4,4'‐bipyridine, hexamethylenetetramine, during the oxidative etching process by bubbling gaseous oxygen in N , ‐dimethylformamide solution. These not only serve but also significantly affect resulting structures. synergistic effect structure confinement functionalization leads superb Faradaic efficiency (FE) 51.9% C H 4 respectively, together partial current density –209.4 mA·cm −2 at –0.8 V vs. reversible hydrogen electrode (RHE). relatively high selectivity towards was investigated DFT simulations, where 4,4'‐bipyridine functionalized seemed favor formation low free energy intermediates. This study provides feasible manipulate regulating process, which sheds light on rational preparation high‐performance RR electrocatalysts.
