Abstract
Chloroplast-like structures of Bi2S3-ZnS was prepared by facile and convenient solvothermal process. The controlled morphology was achieved by regulating the concentration of PVP in the reaction mixture and reaction time. Role of PVP and its effect on morphology has been explored by varying it concentration in the reaction mixture. The formation mechanism has been probed, proposed and discussed through time dependent study. The photocatalytic activity of the prepared product was evaluated for hydrogen production under visible light irradiation. The successful synthesis of chloroplast-like structures of Bi2S3ZnS may provide some insight to design the other semiconductors for their potential photocatalytic activity. (C) 2016 Elsevier B.V.
