摘要:

本文通过溶胶–凝胶法制备氮硫钒共掺杂的具有较高可见光催化活性的二氧化钛。并用均匀实验、二次多项式逐步回归分析和规划求解来使制备过程中氮、硫和钒的掺杂比例最优化。氮硫钒共掺杂可以使二氧化钛的带隙缩小至2.65~2.93 eV。在可见光(λ ≥ 400 nm)下照射3 h后，优化后的共掺杂二氧化钛催化剂对活性蓝的降解率最高可达90.40%。

Nitrogen, sulfur and vanadium co-doped TiO2 photocatalysis with high visible light activities were synthesized through sol-gel process. Uniform design, quadratic multinomial stepwise regression analysis and programming solver were performed for co-doped TiO2 catalyst preparation optimization. The N, S and V co-doping narrowed band gap energy of TiO2 photocatalysis to the range of 2.65 to 2.93 eV. The photocatalytic degradation rate of reactive blue by optimal co-doped TiO2 catalyst was 90.40% in 3 h under visible light irradiation (λ ≥ 400 nm).
