A single-source precursor route to Ag/SnO2 heterogeneous nanomaterials and its photo-catalysis in degradation of Conco Red

Abstract Ag/SnO 2 heterogeneous material was obtained via directly decomposing single-source precursor Ag 2 SnO 3 at temperature of 400 °C, owing to the in situ growth from the decomposition. This kind of heterogeneous structure was helpful to improve the photocatalysis efficiency. When Ag/SnO 2 heterogeneous material was employed as photocatalysts in the degradation of Conco Red, its catalytic efficiency is 3-fold that of the mixture of Ag and SnO 2 powders.
