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.

介孔2D / 2D TiO 2(B)-BiOBr异质结光催化降解废水中的混合污染物

实际废水中有多种污染物。混合污染物的光降解是光催化领域的一个挑战。在这里,我们设计了一种中孔2D / 2D TiO 2(B)-BiOBr异质结光催化剂,用于光降解混合污染物。这种偶联结构导致光激发载流子的分离增强,吸收和反应位点增加。2D / 2D TiO 2(B)-BiOBr在可见光下同时具有出色的光催化降解罗丹明B(RhB),甲基橙(MO),四环素盐酸盐(TCH)和双酚A(BPA)的活性,分别为4.7、1.4、23和16.4倍分别比原始BiOBr高。我们的工作为在不久的将来设计有前途且高效的光催化剂用于处理实际废水提供了一种可能的解决方案。
