Well‐dispersed carbon‐doped ZnSn(OH) 6 submicrocubes were successfully synthesized through a facile and economical hydrothermal method at 433K, which used green chemical glucose (C 6 H 12 O 6 ) as the carbon‐doping source. Photocatalytic activity of the as‐synthesized C‐doped ZnSn(OH) 6 was 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) 6 photocatalysts exhibited higher photocatalytic performance as compared to pure ZnSn(OH) 6 . 1.0 wt% C‐doped ZnSn(OH) 6 photocatalyst exhibited obviously higher photocatalytic activity that of pure ZnSn(OH) 6 or other C‐ZnSn(OH) 6 catalysts 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) 6 was discussed.
