摘要：

Photocatalytic degradation is an important method to mediate organic pollution in the environment. This article reports Ag-modified SnO2@TiO2 core-shell composite photocatalysts prepared via a hydrothermal method. The Ag modification and core structure in the composite enhanced the photocatalytic activity and stability of TiO2 in Rhodamine B degradation under visible light irradiation. The composite modified in 0.15 M AgNO3 showed an optimal level of photocatalytic activity, as it degraded 99.14 % Rhodamine B in 60 min while pure TiO2 only degraded 45.7 % during the same time.
