Preparation of Visible Light Response K₆SiW₁₁O₃₉Sn^II for Photocatalytic Degradation of Acid Brilliant Scarlet

Abstract:

Environmental friendly materials, K₆SiW₁₁O₃₉Sn^Ⅱ(abbreviated as SiWSn), was synthesized, which is visible light response photocatalyst. The photocatalytic decomposition of Acid Brilliant Scarlet (abbreviated as ABS) aqueous solution with SiWSn was investigated using a broad spectrum of solar radiation. The results showed that the photocatalytic degradation efficiency of ABS with SiWSn was affected by the initial pH of ABS solution, the amount of SiWSn and the photolysis time. When the initial pH of ABS solution was 5, the initial concentration of that (20mL) was 3mg L^-1, the concentration of SiWSn was 1.25g L^-1, and it was irradiated 4h under the sunlight, the discoloration rate of which was 71.4%.
