以可溶性淀粉为助溶剂，采用溶剂热法合成了具有分级结构的Bi24O31Br10光催化剂。采用XRD、SEM、EDS、TEM、FTIR和N2吸附等手段对样品进行了表征。研究发现，淀粉对Bi24O31Br10的形貌起着关键作用，特别是添加适量的淀粉可以得到一种新型的Bi24O31Br10颗粒状分级结构.提出了不同显微组织的形成机理。以罗丹明B（RhB）为目标染料，考察了其在可见光照射下的光催化降解性能。淀粉对Bi_（24）O_（31）Br_（10）光催化剂的光催化活性有明显的增强作用，并对其机理进行了探讨。本研究为调控材料的结构、形貌和性能提供了一种新的策略，并可推广到其他光催化剂。
Hierarchically structured Bi24O31Br10photocatalysts were synthesized by a facile solvothermal method with the help of soluble starch. As-prepared samples were characterized by XRD, SEM, EDS, TEM, FTIR and N2adsorption. It was found that starch played a key role in shaping morphology of Bi24O31Br10,and especially a novel grain-like Bi24O31Br10hierarchical architecture could be obtained by adding the right amount of starch. The forming mechanisms of different microstructures were proposed. The photocatalytic performances of the obtained samples were also investigated by degradation of Rhodamine B (RhB) under visible light illumination. Starch-modulated Bi24O31Br10photocatalysts exhibited obviously enhanced photocatalytic activity, whose mechanism was discussed. The present work demonstrated a novel strategy to modulate the structures, morphologies and properties of materials, which can be extended to other photocatalysts.
