摘要/Abstract

摘要： 以Bi(NO₃)₃·5H₂O、NaVO₃和Cu(NO₃)₂·3H₂O为原料并以十六烷基三甲基溴化铵(CTAB)为结构导向剂通过水热法制备了Cu/BiVO₄微米片晶体。采用XRD、XPS、SEM、HRTEM、UV-Vis、比表面积测试等对产品进行了表征。结果表明, 2.0 g CTAB辅助水热法能够合成结晶度高且形貌规整的单斜白钨矿Cu/BiVO₄微米片晶体, 其长度为1.0~2.0 μm, 宽度为0.5~2.0 μm, 厚度在200~300 nm内。相比BiVO₄颗粒, 片状Cu/BiVO₄样品的紫外–可见光吸收边发生了稍许红移, 具有较小的能带隙。光催化结果说明, 5.0wt%Cu/BiVO₄微米片表现出最好的光催化活性, 其速度常数k为5.89×10^–2/min, 可见光照射10 mg/L亚甲基蓝溶液60 min的光解率达100%。

Abstract: Using Bi(NO₃)₃·5H₂O, NaVO₃ and Cu(NO₃)₂·3H₂O as raw materials, Cu-doped BiVO₄ microsheets were synthesized by ultrasonic-hydrothermal process with cetyltrimethyl ammonium bromide (CTAB) as template. The as-prepared samples were investigated by XRD, XPS, SEM, HRTEM, UV-Vis and BET tests. The results reveal that uniform and well crystallized Cu/BiVO₄ microsheets in monoclinic crystal structure, with length of 1.0–2.0 μm, width of 0.5–2.0 μm and thickness of 200–300 nm, could be obtained via an ultrasonic-hydrothermal route assisted by 2.0 g CTAB. Compared with BiVO₄ particles, Cu/BiVO₄ nanosheets show a little red shift in the absorption band, resulting in a narrowed band gap (<2.4 eV). For 5.0wt% Cu/ BiVO₄ microsheet, its photodegradation rate constant K is 5.89 ×10^–2 /min and the best photocatalytic activity is found with a 100% degradation of methylene blue (MB) with 10 mg/L concentration under visible-light irradiation for 60 min.
