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.

增强光催化性能的二维/二维方形BiOCl/g-C3N4异质结在可见光照射下的简易合成
以甘露醇为原料,用简单的方法制备了一种新型的2D/2D方形BiOCl/g-C3N4异质结光催化剂。正方形的BiOCl均匀地分散在g-C3N4表面。考察了Bi用量对复合材料结构和性能的影响,在可见光照射3 h后,最佳样品对RhB的降解率为93.87%,分别是纯g-C3N4和纯BiOCl的7.39倍和3.09倍。光催化效率的提高可归因于光生电子和空穴复合的减少。超氧阴离子自由基和光生空穴是两种主要的活性物质。

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.
