Abstract

In this study, graphitic carbon nitride was engineered to produce metal-free melem/g-C₃N₄ hybrid photocatalysts through a hydrothermal technique. It was revealed that the hydrothermal treatment of g-C₃N₄ could produce a hybrid structure of "thorn ball" liked melem on g-C₃N₄ layer at a high temperature, and was able to modify the photoelectronic properties of g-C₃N₄. The spectroscopic measurements implied that a melem/g-C₃N₄ hybrid has better light absorption and lower electron/hole recombination than pristine g-C₃N₄. Therefore, the melem/g-C₃N₄ photocatalysts can decompose methylene blue solution under artificial sunlight with a higher rate and also present good stability.
