过渡金属磷化物在光催化领域的应用

o efficiently utilize solar energy and store it in hydrogen and hydrocarbon fuels, efficient, stable and inexpensive photocatalysts for hydrogen precipitation and CO2 reduction need to be designed and synthesized. Most of the currently reported photocatalysts have low photocatalytic efficiency due to the easy binding of electrons and holes, which limits their practical applications. Therefore, co-catalysts have been introduced to improve the photocatalytic efficiency. However, the high price and scarcity of noble metal-based co-catalysts used by previous researchers have limited their development in photocatalysis, so there is an urgent need to study and find alternatives to noble metals. Among them, transition metal phosphides (TMPs) are widely cited in the field of photocatalysis due to their unique electronic structure and noble metal-like properties. This review focuses on the recent progress of TMPs for photocatalytic CO2 reduction and hydrogen precipitation, and also summarizes the challenges that TMPs will encounter during their rapid development and provides an outlook on the future direction.
