碳基材料的Z型和S型异质结光催化清洁能源综述OA北大核心CSTPCD

Carbon materials,including carbon nanotubes/nanofibers,graphene,graphene oxide,reduced graphene oxide,graphyne,graphdiyne,carbon quantum dots and fullerenes,have received considerable attention in recent years because of their unique properties such as high conductivity,excellent stability and biocompatibility.The integration of these materials into Z-scheme and S-scheme heterojunctions has emerged as a transformative strategy to increase their photocatalytic efficiency for energy conver-sion applications.We first consider the fundamental principles of clean energy generation such as photocatalytic H2 generation and CO2 reduction,elucidating their respective mechanisms and advantages.Various types of carbon materials,their synthesis and con-struction of Z-scheme and S-scheme heterojunctions are then discussed,emphasizing their role in promoting charge separation,redu-cing recombination losses and extending the spectral response range.With a focus on solar energy production,recent advances in carbon-based Z-scheme and S-scheme heterojunctions are discussed and summarized for photocatalytic H2 generation and CO2 re-duction.Lastly,the current problems in the field of carbon-based photocatalysts are discussed with insights for the future develop-ment of this field.
