TL;DR: This review attempts to summarize the recent progress in the rational design and fabrication ofheterojunction photocatalysts, such as the semiconductor-semiconductor heterojunction, the semiconductors-metal heterojunctions, the silicon-carbon heteroj junction and the multicomponent heteroj conjunction.

TL;DR: This is one of the very few studies dealing with chlorinated organic intermediates formed via chlorine radical/active chlorine species (HOCl/Cl(2)) attack on dye compounds, and this finding may have significant technical implications for utilizing Co/PMS regent to detoxify chloride-rich azo dyes wastewater.

TL;DR: Orange II (Org II), one of the most common used azo dyes, was taken as a model to investigate the effects of chloride ion on dye decoloration in cobalt/peroxymonosulfate (Co/PMS) system, and a significant decrease in the rate of Org II decolored was observed, but further addition of Cl(-) apparently accelerated dyes degradation.

TL;DR: In this article, a sequential reduction/oxidation strategy for photocatalytic degradation of tetrabromobisphenol A (TBBPA), one of the most frequently used brominated flame retardants, was proposed on the basis of kinetic analysis and intermediates identification.

TL;DR: In this article, the authors summarize the recent progress in the rational design and fabrication of heterojunction photocatalysts, such as the semiconductor-semiconductor, semiconductor−metal, polysilicon, polycarbon, and multicomponent heterojunctions, and conclude with a summary and some perspectives on the challenges and new directions in this still emerging area of research.
