Hydrogen energy is a globally recognized clean new energy,and photocatalytic hydrogen production is an important hydrogen preparation technology.Wide band gaps,low photocatalytic performance,and facile electron-hole recombination are all technological barriers in commonly used photocatalysts.Modifying photocatalysts using rare earth metals can significantly boost the catalytic impact of hydrogen production.This article comprehensively reviews the current research status of hydrogen production with rare earth modified photocatalysts in China and abroad,and compares the mechanism and effects of rare earth modified photocatalysts such as La(lanthanum)and Ce(cerium).It also investigates the impact and effect of rare earth modified photocatalysts on light usage,visible light responsiveness,and electron-hole recombination.Finally,it suggests a strategy for future study on hydrogen generation utilizing rare earth modified photocatalysts.
