Recently, the latest achievement of metal sulfide as highly efficient visible light driven photocatalyst for H2 production from H2S was published on Applied Catalysis B: Environmental. The robust MnS/(InxCu1-x)2S3 composite photocatalyst were successfully fabricated for photocatalytic H2 production from H2S for the first time. The maximum H2 production rate of 29,252 μmol h-1 g-1 is achieved over the optimized MnS/(InxCu1-x)2S3 composite under visible-light irradiation (λ > 420 nm). The corresponding AQE at 420 and 450 nm is 65.2% and 62.6%, respectively, which are the highest so far for the visible light photocatalytic splitting of H2S in the absence of noble- metal co-catalysts. This study does not only report a highly active non-noble metal photocatalyst but also provides a novel “Solid Solution-Heterojunction” strategy for boost photocatalytic H2 production from a highly toxic pollutant.
