Synthesis of highly efficient novel two-step spatial 2D photocatalyst material WS2/ZnIn2S4 for degradation/reduction of various toxic pollutants

All-inorganic lead halide perovskites for photocatalysis: a review

“…However, independent photocatalysts with E g less than 3 eV, such MoS 2 , WO 3 , and C 3 N 4 , are impacted by the quick recombination of photogenerated carriers even though they exhibit photocatalytic activity under visible light irradiation. In short, these conventional photocatalysts still have several issues such as poor light absorption, 32 low quantum efficiency, [33][34][35][36] high interfacial charge transfer resistance, 37 and rapid photogenerated carrier complexation, [38][39][40][41] thus signicantly restricting the development and practical applications of photocatalysis. A range of efficient techniques, such as doping, implementing cocatalysts, building heterostructures, as well as controlling the morphology and crystallography, have been employed to conquer the aforementioned drawbacks and enhance the photocatalytic activity (Table 1).…”
