以绿色化学葡萄糖(C6H12O6)为碳掺杂源，在433K下，采用简便、经济的水热法成功地合成了分散良好的碳掺杂亚微米级锌锡锡氧化物。在可见光(≥，400 nm)照射下，研究了水溶液中亚甲基蓝(MB)的光催化分解，评价了所合成的C掺杂ZnSnO(OH)6的光催化活性。结果表明，碳掺杂的锌锡(OH)6光催化剂的光催化活性明显高于纯的锌锡锡(OH)6催化剂；在相同条件下，1.0wt%C掺杂的锌锡(OH)6光催化剂的光催化活性明显高于纯的锌锡(OH)6或其他C-锌锡(OH)6催化剂。亚甲基蓝的光催化降解增强归因于碳的掺杂，并讨论了碳掺杂的氢氧化锌具有较高光催化活性的可能机理。
Well‐dispersed carbon‐doped ZnSn(OH)6submicrocubes were successfully synthesized through a facile and economical hydrothermal method at 433K, which used green chemical glucose (C6H12O6) as the carbon‐doping source. Photocatalytic activity of the as‐synthesized C‐doped ZnSn(OH)6was evaluated by studying photocatalytic decomposition of methylene blue (MB) in aqueous solution under visible light irradiation(≥ 400 nm). The results show that carbon‐doped ZnSn(OH)6photocatalysts exhibited higher photocatalytic performance as compared to pure ZnSn(OH)6. 1.0 wt% C‐doped ZnSn(OH)6photocatalyst exhibited obviously higher photocatalytic activity that of pure ZnSn(OH)6or other C‐ZnSn(OH)6catalysts under the same condition. The enhanced photocatalytic degradation of MB could be attributed to the doping of carbon and the possible mechanism for high photocatalytic activity of C‐doped ZnSn(OH)6was discussed.
