Novel Sn3OSO4(OH)2 Photocatalyst for Efficient Degradation of Methyl Orange

Sn3OSO4(OH)2 was successfully synthesized using a simple solid-state reaction method. The material was applied to the photocatalytic degradation of industrial dyes. Experimental results indicated that the material could be rapidly synthesized through a straightforward vibration treatment of NaOH and SnSO4 powders for 5 min. Its average particle size was 14 μm. The BET value was 1.32 m2/g. It had stronger light absorption ability in visible regions. Sn3OSO4(OH)2 exhibited good photocatalytic performance under UV and simulated sunlight irradiation. It could completely degrade methyl orange in 92 and 45 min under the two conditions, respectively. Finally, a mechanism of photocatalytic degradation of MO by Sn3OSO4(OH)2 was proposed.
