Controllable Crystal Growth and Improved Photocatalytic Activity of Porous Bi₂O₃-Bi₂S₃ Composite Sheets.

ABSTRACT: Porous Bi₂O₃-Bi₂S₃ composite sheets were constructed through a combinational methodology of chemical bath deposition and hydrothermal reaction. The Na₂S precursor concentration in the hydrothermal solution was varied to understand the correlation between the vulcanization degree and structure evolution of the porous Bi₂O₃-Bi₂S₃ composite sheets. The control of the etching rate of the Bi₂O₃ sheet template and the regrowth rate of Bi₂S₃ crystallites via suitable sulfide precursor concentration during the hydrothermal reaction utilizes the formation of porous Bi₂O₃-Bi₂S₃ sheets. Due to the presence of Bi
