摘      要：Fabricating an efficient charge transfer pathway at the compact interface between two kinds of semiconductors is an important strategy for designing hydrogen production heterojunction *** this work,we prepared a compact,stable and oxygen vacancy-rich photocatalyst(SnO_(2)/TiO_(2) heterostructure)via a simple and reasonable in-situ synthesis ***,SnCl_(2)–2H_(2)O is hydrolyzed on the TiO_(2) *** the pyrolysis process,SnO_(2) nanoparticles(5 nm)were dispersed on the surface of ultrathin TiO_(2) nanosheets ***,the heterojunction system can offer abundant oxygen vacancies,which can act as active sites for catalytic ***,the interfacial contact of SnO_(2)/TiO_(2) grading semiconductor oxide is uniform and tight,which can promote the separation and migration of photogenerated *** shown in the experimental results,the hydrogen production rate of SnO_(2)/TiO_(2) is 16.7 mmol h^(-1)g^(-1)(4.4 times higher than that of TiO_(2)),which is owing to its good dynamical *** work demonstrates an efficient strategy of tight combining SnO_(2)/TiO_(2) with abundant oxygen vacancies to improve catalytic efficiency.
