ar0005">SnOx/Zn2SnO4 composite photocatalyst was prepared by a one-pot hydrothermal method.
ar0010">SnOx refers to SnO2 accompanied by trace amount of Sn2O3.
ar0015">A type-II heterojunction is formed between SnOx and Zn2SnO4.
ar0020">The heterojunction leads to a wide separation of e− and h+.
ar0025">SnOx/Zn2SnO4 shows high activity for the degradation of MO and gaseous benzene.
