摘要
PW杂多酸具有良好的化学特性,被广泛的应用于化工催化合成、氧化等多个领域。采用水热合成法合成出一种具有新奇三维空间结构的PW杂多酸(C_2H_9N_2)_4(C_2H_(10)N_2)[Co_3W_4P_4O_(28)],对其进行结构表征。用H_2O_2对其进行敏化,采用500 W的氙灯照射,催化处理甲基橙模拟废液。对甲基橙溶液的初始浓度,溶液p H及PW杂多酸用量进行优化。实验发现,当甲基橙溶液的浓度为10 mg/L,PW杂多酸用量为2 g/L,pH为1时,甲基橙的降解率达到最大值,为78.32%,具有一定的工业研究价值。
Polyoxometalates （ POMs ） have attracted considerable attention because of their potential application in the field of industrial catalysis. In the present paper,a kind of POM （C2H9N2）2（C2H10N2） [ Co3 WO4 O28 ] with novel three-dimensional structure has been synthesized by using hydrothermal process. Moreover,it has been employed as a catalyst for the oxidization of methyl orange in the present of H2 O2 . The reaction conditions including initial concentration of methyl orange,pH,and the amount of catalyst have been optimized. We found the an optimal condition,pH equals to 1,the concentration of methyl orange is 10 mg/L, the amount of catalyst is 2 g/L,can lead to a 78. 32 % degradation of methyl orange.
