Photoelectrochemical (PEC) reduction of CO2 with H2O into syngas is an effective way to relieve the greenhouse effect and produce valuable chemicals. In this study, controllable PEC reduction of CO2 with H2O to syngas is achieved by the Cu2O‐SnOx hybrid nanowires (NWs) photocathode, which can effectively produce the mixture of syngas (CO and H2) with a total Faradaic efficiency of 90.32% at −0.35 V versus RHE. In addition, the CO/H2 ratio of syngas can be adjusted in a wide range from 2.2:1 to 4.6:1. The investigations of linear sweep voltammetry, incident photon to current efficiency, electrochemical impedance spectroscopy, and temperature programmed desorption indicate that the charge transfer efficiency and CO2 adsorption capacity are highly enhanced by the electrodeposition of SnOx on the Cu2O NWs electrode. In situ diffuse reflectance Fourier transformed infrared spectroscopy spectra results indicate that visible light irradiation can accelerate the accumulation of CO2 reduction intermediates and thus facilitate the release of CO. This study provides an available way for the rational development of high‐performance PEC systems for CO2 reduction to valuable carbon‐based compounds, as well as a new strategy for atmospheric CO2 treatment.

Electrocatalytic CO2 reduction (eCO2RR) is one of the avenues with most potential toward achieving sustainable energy economy and global climate change targets by harvesting renewable energy into value‐added fuels and chemicals. From an industrial standpoint, eCO2RR provides specific advantages over thermochemical and photochemical pathways in terms of much broader product scope, high product specificity, and easy adaptability to the renewable electricity infrastructure. However, unlike water electrolyzers, the lack of suitable cathode materials for eCO2RR impedes its commercialization due to material design challenges. The current state‐of‐the‐art catalysts in eCO2RR suffer largely from low reaction rates, insufficient C2+ product selectivity, high overpotentials, and industrial‐scale stability. Overcoming the scientific and applied technical hurdles for commercial realization demands a holistic integration of catalytic designs, deep mechanistic understanding, and efficient process engineering. Special emphasis on mechanistic understanding and performance outcome is sought to guide the future design of eCO2RR catalysts that can play a significant role in closing the anthropogenic carbon loop. This article provides an integrative approach to understand principles of robust eCO2RR catalyst design superimposed with underlying mechanistic projections which strongly depend on experimental conditions viz. choice of electrolyte, reactor and membrane design, pH of the solvent, and partial pressure of the CO2.
