英文摘要Interfacial photo generated charge separation and trans-port have demonstrated great influence on photocatalytic performance.Herein, the composite photocatalysts of methylammonium lead iodideperovskite (MAPbI3) in TiO2with a hollow multishell structure(HoMS) are designed and synthesized. The results indicate that theheterogeneous interface within the MAPbI3/Pt/TiO2-HoMS can helpenhance the separation of photogenerated charges. HoMSs assembledwith multiple shells can not only support large surfaces available forbuilding a heterogeneous interface and photocatalytic reactions but alsoimprove the light absorption capability of photocatalysts. Besides, thethin shell structure can also reduce the transmission distance of carriersso as to hinder charge recombination and improve charge utilization. Asa result, samples of MAPbI3/Pt/triple-shelled TiO2hollow structuredisplayed a H2yield of 6856.2 mu mol h-1g-1under visible light, which is greatly better than that of bare MAPbI3(268.6 mu mol h-1g-1)
