摘 要：There are multiple contaminants in practical wastewater; and the photodegradation of mixed pollutants is a challenge in the field of photocatalysis. Herein, we design a mesoporous 2D/2D TiO2（B）-BiOBr heterojunction photocatalyst for the photodegradation of mixed pollutants. Such a coupling structure results in an enhancement in the disconnection of photoexcited carriers, and the increase of absorption and reaction sites. The 2D/2D TiO2（B）-BiOBr demonstrates outstanding photocatalytic activity for photodegrading rhodamine B（RhB）, methyl orange（MO）, tetracycline hydrochloride（TCH）, and bisphenol A（BPA）simultaneously under visible light, which is 4.7, 1.4, 23 and 16.4 times as high as that of original BiOBr,respectively. Our work represents a possible solution to devise promising and efficient photocatalysts for the treatment of practical wastewater in the near future.
