主　　题：Carbon nitride CdS Macropore Photocatalytic H2 evolution 

摘      要：Carbon nitride(g-C_(3)N_(4))is an attractive photocatalyst but commonly suffers from high photogenerated electron-hole recombination rate,low specific surface area,and narrow visible-light response ***,3D ordered macroporous(3DOM)g-C_(3)N_(4)/CdS was constructed by a feasible and inexpensive synthesis strategy of using template and light-assisted methods to solve the above *** formed heterostructure with suitable morphology,band structure,and extended light absorption range is beneficial to promoting photocatalytic Hgeneration.3DOM g-C_(3)N_(4)/Cd S exhibits a high Hproduce rate of718.6μmol hg,which is 73.3 times higher than that of g-C_(3)N_(4)and 25.4 times higher than that of3DOM g-C_(3)N_(4).The 3DOM structure can effectively increase the path length of light of g-C_(3)N_(4),improve the light energy conversion efficiency,and shorten the carrier transport *** enhances visiblelight response and produces many surface *** a stable and tight interface between 3DOM g-C_(3)N_(4)and Cd S can promote the migration of photogenerated electrons and holes and consequently the visible-light catalytic *** study offers an effective designing strategy for heterostructure photocatalysts to achieve high activity and stable solar H2production.
