摘　　要：采用酸化聚合法制备了钒掺杂十聚钨酸四丁基铵盐(TBA_(4)W_(10-n)V_(n)O_(32))光催化剂,用UV-Vis、FT-IR、XRD及元素分析等对催化剂进行表征,以可见光下催化分子氧氧化苯甲醇为探针反应,考察了TBA_(4)W_(10-n)V_(n)O_(32)催化剂的光催化性能,并研究了水和酸添加剂对光催化氧化性能的影响。结果表明,在优化的V掺杂量和光催化反应条件下,可获得57.0%的苯甲醇转化率和76.8%的苯甲醛选择性。Vanadium-doped decatungstate(TBA_(4)W_(10-n)V_(n)O_(32))was synthesized by acidification polymerization and characterized by UV-vis,FT-IR,XRD and elemental analysis.The photocatalytic performance of TBA_(4)W_(10-n)V_(n)O_(32) was investigated using visible-light driven benzyl alcohol oxidation with molecular oxygen as the probe reaction,including the influence of water and acid additives.The results indicated that benzyl alcohol conversion of 57.0%and selectivity to benzaldehyde of 76.8%was obtained under optimized V doping quantity and photocatalytic reaction condition.
