Sn3O4is a promising, low-cost, nontoxic catalyst with suitable bandgap structure for visible-light hydrogen evolution reaction (HER). The micro-structural modifications leading to more efficient charge separation is essential for improving the photocatalytic performance. In this study, a novel Sn3O4/polypyrrole (PPy) heterostructure photocatalyst with porous Sn3O4nanosheetsin-situanchored on PPy hollow nano rod was constructed through a two-step method combining chemical oxidative polymerization and hydrothermal process. The best hydrogen photo-generation performance was obtained for Sn3O4/2.44 wt%PPy heterostructure reaching 481.05 μmol gcatalyst−1H2within 5 h, which is 7.52 times higher than that of pure Sn3O4. The enhanced hydrogen photo-generation performance can be attributed to the effective charge transfer induced by the electron collector PPy which triggered the photo-induced e- directionally migration and the unique 3D micro-structure of this Sn3O4/PPy photocatalyst.
