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.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
