摘要:
以累托石(Rec)为载体,采用简单易行的共沉淀法制备了Rec/Cu2O/TiO2光催化剂。研究了Rec用量对Cu2O/TiO2形貌及结构的影响。通过X射线衍射、扫描电子显微镜、透射电子显微镜、紫外可见光漫反射对产物进行了表征,结果表明三元材料中的Cu2O具有较好的纯度,Rec的特征衍射角度有所偏移,这是由于三者之间的存在较强的相互作用。Rec可以调控Cu2O的生长聚集,球状的Cu2O/TiO2较为均匀地附着在Rec表面。Rec/Cu2O/TiO2具有较好的可见光响应能力。光催化除藻的实验结果表明,适量Rec的添加能够提高其光催化除藻的效率,当Rec含量为0.3 g的时具有最好的除藻效率。此外,3次循环实验后,催化剂的光催化除藻效率无明显下降,表明本实验所制备的光催化材料具有较好的稳定性及实用性。
Abstract:
Abstract: Rectorite(Rec)/Cuprousoxide(Cu2O)/Titanium dioxide(TiO2) photocatalysts were prepared by the simple coprecipitation method with Rec as a carrierr. Effects of Rec amount on the morphology and structure of Cu2O/TiO2 were investigated. The characterization results of X-ray diffraction, scanning electron microscopy, transmission electron microscopy and ultraviolet-visible diffuse reflection indicated that cupper in this ternary material were purely presented as Cu2O, and the characteristic diffraction peaks of Rec were shifted due to the strong interaction between the three materials. Rec regulated the growth and aggregation of Cu2O, leading to the uniform dispersion of spherical Cu2O/TiO2 on the surface of Rec. The Rec/Cu2O/TiO2 exhibited good visible light response performances. The appropriate amount of Rec (0.3 g) could increase the efficiency of photocatalytic removal of algae. Additionally, the photocatalytic efficiency of the catalyst did not decrease significantly after cyclic tests for three times, which indicated that the prepared photocatalyst possessed good stability and practicality.
