Synthesis and characterization of carbon‐doped ZnSn(OH)₆ with enhanced photoactivity by hydrothermal method

Abstract

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 carbondoped 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.

Recent Development of Photocatalysts Containing Carbon Species: A Review

“…This work provided a solid basis for the rationalization of the experimentally observed red shift of optical absorption in wurtzite ZnS as a consequence of (N, C) co-doping. Recently, a hydrothermal method was developed to synthesize well-dispersed carbon-doped ZnSn(OH) 6 submicrocube photocatalysts at 433 K using glucose as the carbon-doping source [94], which exhibited higher photocatalytic performance by the decomposition of methylene blue in aqueous solution under visible light irradiation, compared with pure ZnSn(OH) 6 .…”

Z-scheme TiO2@Ti3C2/Cd0.5Zn0.5S nanocomposites with efficient photocatalytic performance via one-step hydrothermal route

“…pollution, have become issues that need to be urgently solved. Photocatalytic degradation of organic pollutants with low cost and no secondary pollution has become an important research focus of environmental science [1][2][3][4][5][6]. TiO 2 nanomaterials are widely used in the field of photocatalysis due to their good chemical stability, non-toxic and easy access, which have been employed for the degradation of organic wastewater [7][8][9][10].…”
