摘要
以自制的多金属氧酸盐Zn1.5PW12O40纳米管作为催化剂,以空气作为氧化剂,对碱性藏花红进行了催化氧化实验。结果表明:中空结构、纳米级Zn1.5PW12O40适合用作催化剂。空气氧化体系中的催化氧化最佳反应时间为4h,降解率达到78%,降解速率达到665μg/h;催化剂的活性和稳定性均较高,循环使用4次时降解率仍>65%。
Technology of catalytic oxidation was studied for degrading safranine T, with self-made polyoxometalate Zn1.5W12O4O nanotube as catalyst and dioxygen as oxidant. Results showed that Zn1.5W12O40 was suitable for catalyst, with hollow structure, affiliated to the type of heteropoly acids and at nanometer scale. In the oxidation system of air, under optimum reaction time of 45h, correspondently degradation rate and degradation velocity were 78% and 665μg/h respectively. Catalyst activity and stability were both high, and when circulation times were four, degradation was still 65%.
