  • 摘要: 以铜金属有机骨架材料Cu3（BTC）2·12H2O（Cu-BTC）为前驱体，通过浸渍还原方法成功制备出粒径为20-30 nm的Fe0-Cu0双金属催化剂.为评估该双金属催化剂对过硫酸钠（PS）的催化活性，对邻苯二甲酸二丁酯（DBP）进行氧化降解研究.考察了Fe0/Cu0的摩尔比、PS浓度、催化剂用量及初始pH对DBP降解的影响.结果表明在Fe0/Cu0 <1.0时，DBP的降解去除率随着双金属催化剂Fe0/Cu0摩尔比的增加而增大.DBP的降解率随着PS和Fe0-Cu0双金属催化剂浓度的增加而增大，并在PS和Fe0-Cu0浓度分别为1.62 mmol·L-1和0.3 g·L-1时达到最佳去除效果.除pH值为7.0外，DBP的降解率随着初始pH值的增加而下降.
    Abstract: Metal-Organic Framework (MOF) material Cu-BTC immersed with ferrous solutions was reduced to iron/copper (Fe0-Cu0) bimetallic particles.with with an average size of ca.20-30 nm The catalytic performance of Fe0-Cu0 bimetallic particles was evaluated to catalyze persulfate for degradation of dibutyl phthalate (DBP). Effects of molar ratios of Fe0/Cu0, persulfate concentration, Fe0/Cu0 dosages and initial pH on DBP degradation were investigated, respectively. The results indicated that DBP removal was increased with increase of the molar ratios of Fe0/Cu0 while the molar ratios of Fe0/Cu0 was less than 1.0. DBP degradation rates also increased with the increase of catalysis dosages and persulfate concentration, which showed highest removal efficiency at the concentrations of 0.3 g·L-1 and 1.62 mmol·L-1 respectively. Besides pH 7.0, the removal efficiency of DBP decreasd with the increase of initial pH values.
