摘要: 本实验研究以Bi(NO3)3和KCl为反应物，采用简单溶剂热法合成了新颖的三维花状BiOCl纳米分级结构。BiOCl纳米分级结构的形貌强烈依赖于反应条件，例如KCl/Bi(NO3)3比例、有机溶剂存在与否以及水热反应时间。运用X射线衍射(XRD)、X射线光电子能谱(XPS)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和N2吸附脱附等表征手段对实验样品进行了表征。而且，光催化活性测试实验表明所合成的花状BiOCl纳米分级结构对罗丹明B(RhB)和甲基橙(MO)染料水溶液的降解表现出很高的活性。有趣的是，样品对RhB碱性染料的降解比MO酸性染料更加迅速，可能是由于BiOCl纳米花状结构表面的负电荷因静电吸引作用而对呈正电性的RhB染料有机基团表现出很高的选择吸附性。
Abstract: Novel three-dimensional (3D) flowerlike BiOCl nanoarchitectures were synthesized via a facile solvothermal process only usingBi(NO3)3 and KCl as precursors. The morphology of BiOCl nanoarchitecture is strongly dependent on the reaction conditions such as the ratio of KCl/Bi(NO3)3, presence of organic solvent, and hydrothermal time. The products were characterized by XRD, SEM, TEM and nitrogen sorption. Furthermore, the photocatalytic activity experiment illustrated that as-synthesized flowerlike BiOCl nanoarchitectures exhibited an excellent photocatalytic activity for the degradation of RhB and MO dye aqueous solution. Interestingly, the degradation of RhB basic dyes is faster compared to that of MO acid dyes. That is due to the fact that the surface negative charges of BiOCl nanoflowers present good selectivity toward positive RhB dye organic groups because of the electrostatic attraction.
