Optimal monolayer WO3 nanosheets/TiO2 heterostructure and its photocatalytic performance under solar light

Highly efficient photocatalysts were formed via high-temperature calcination of monolayer WO3 prepared by a space-constrained method combined with commercial TiO2, and the optimal ratio of these components was explored. These synthetic catalysts were also characterized. During photocatalysis, the decomposition rate of MB achieved by the 1 mol% ML-WO3/TiO2 composite reached 98.05% within 10 min under solar light. Moreover, the photocatalytic efficiency of the composite catalyst did not decrease substantially after 5 cycles of operation. In addition, energy band position and active gene capture experiments revealed that the prepared photocatalysts conform to the transfer theory of Z-scheme heterojunctions.

Automated summary
