Abstract

The morphology and size of photocatalyst directly affect the spectral absorption, adsorption and degradation efficiency for pollutants, which are the key factors affecting photocatalytic performance. The unique layered crystal structure of BiOBr makes it easy to grow along the (001) direction to form two-dimensional sheets, but the synthesis of BiOBr nanospheres has not been reported. In this work, BiOBr nanospheres with a size less than 50 nm were synthesized by solvothermal method for the first time. The organic bromine source (1, 2-dibromobenzene) and high reactant concentration are the two main conditions for the synthesis of BiOBr nanospheres. BiOBr nanospheres could rapidly degrade Rhodamine B dye under visible light irradiation. The results could provide a novel process for the controlled preparation of BiOBr and more research basis for the deep photocatalytic degradation of printing and dyeing wastewater.

1,2 -二溴苯溶剂热合成BiOBr纳米球

光催化剂的形态和尺寸直接影响对污染物的光谱吸收、吸附和降解效率，是影响光催化性能的关键因素。BiOBr 独特的层状晶体结构使其易于沿（001）方向生长形成二维薄片，但合成 BiOBr 纳米球的方法尚未见报道。本研究首次采用溶热法合成了尺寸小于 50 nm 的 BiOBr 纳米球。有机溴源（1，2-二溴苯）和高反应物浓度是合成 BiOBr 纳米球的两个主要条件。在可见光照射下，BiOBr 纳米球能快速降解罗丹明 B 染料。该研究成果可为 BiOBr 的可控制备提供一种新工艺，并为印染废水的深度光催化降解提供更多的研究基础。
