Abstract

A novel 2D/2D foursquare BiOCl/g-C₃N₄ heterojunction photocatalyst was fabricated using mannitol by a simple method. Square sheets of BiOCl were dispersed on the surfaces of g-C₃N₄ uniformly. The influence of Bi dosage on the structure and performance of the composite was investigated and the best sample could degrade 93.87 % of RhB after visible-light irradiation for 3 h, which was 7.39 and 3.09 times higher than pure g-C₃N₄ and pure BiOCl, respectively. The enhanced photocatalytic efficiency can be attributed to the reduced recombination of photogenerated electrons and holes. Superoxide anion radicals and photogenerated holes are the two main active species.
