Abstract

Abstract:

A graphitic carbon nitride/cyanuric chloride(g-C₃N₄/C₃Cl₃N₃) composite photocatalyst was developed. The obtained catalyst effectively expands π-conjugated system of g-C₃N₄. Moreover, the band gap is significantly shifted, and the reduction ability of the photo generated charge is improved because of the introduction of a chlorine atom. The catalyst can effectively degrade organic pollutants under visible light. The result shows that the degradation ratio of reactive red-dye is 94.7% and is still kept at 94% after using 5 times. The mechanism on the degradation of organic pollutants under visible light was studied.

Key words: graphitic carbon nitride, cyanuric chloride, reactive red, visible light catalysis
