Recent advances of the catalysts for photoelectrocatalytic oxygen evolution and CO2 reduction reactions

Increasing global energy consumption and environmental pollution make the use of new energy sources and environmentally friendly technologies essential to meet the diverse needs of industries. Photoelectrocatalysis is a promising method of utilising solar and electrical energy for various catalytic reactions with significant environmental and energy saving benefits. And photoelectrocatalytic (PEC) oxygen evolution reaction (OER) and CO2 reduction reaction (CO2RR) are two catalytic reactions with great potential for energy and environmental applications. PEC OER is critical for renewable energy technologies for water oxidation and other related oxidation reactions. PEC CO2RR converts carbon dioxide into high-value products via a catalyst, enabling the rational use of carbon dioxide and the reduction of greenhouse gas emissions. Both technologies are efficient, environmentally friendly, and sustainable. However, further research and optimisation are needed to promote the industrial application of both technologies for energy conversion and environmental protection. This paper reviews the research progress of PEC CO2RR and OER catalysts in recent years, including detailed descriptions of catalyst types, reaction mechanisms and performance tests. Finally, the paper considers the future trends and prospects of PEC technology, providing new insights into the technology and research directions for PEC OER and CO2RR catalysts.
