Photocatalytically reducing CO2 by H2O into valuable carbon-containing chemicals is one of the greatest concerns for both scientific and industrial communities, due to its great potential in solving energy and environmental problems. However, the photocatalytic reduction efficiency is still much lower than the need of large-scale applications. Abilities of photocatalysts in adsorbing CO2 and splitting H2O to produce protons are crucial factors determining the photocatalytic reduction efficiency. Significant research efforts have been devoted to addressing the issues on CO2 adsorption and proton production. The present review discusses the recent progresses in improving CO2 adsorption and proton production on photocatalysts for increasing the photocatalytic reduction efficiency. Future research opportunities and challenges are also discussed. It is hoped that the present review can stimulate more deep insights on adsorption of CO2 and production of proton for increasing the photocatalytic reduction efficiency.
