Structure-mechanism relationship for enhancing photocatalytic H2 production

Clean and renewable energy plays important role in achieving carbon neutrality and na-ture sustainability, especially the application of green hydrogen in new energy system. Hydrogen (H2) produced from visible light has attracted attention owing to its high con-version efficiency and cleaner process. In this review, different photocatalyst preparation methods which can directly design the same structure were clarified. Also, different mechanism design which can realize different electron transfers were also proposed. Thus, various morphologies and different mechanisms of electron transfer have been summa-rized and evaluated. Also, the methods of photocatalysts' construction were mentioned, all H2 production reactions depend on the amount of reaction sites and photo-generate electrons. It was evident that the concentration of reaction sites and photo-generate electrons play important roles in efficient H2 production. This review provides funda-mental knowledge to design and construct variable morphologies with different electron transfer processes to enhance efficiency of H2 production.(c) 2022 Hydrogen Energy Publications LLC.
