摘要: 在超声波作用下以硝酸银和碳酸钠制备超细碳酸银粉末,在冰浴条件下采用吡咯的原位聚合法,以过硫酸铵为氧化剂,制备聚吡咯-碳酸银复合材料,并以IR 及激光粒度仪对复合材料进行了表征。将复合材料作为催化剂,模拟自然光照射下降解甲基橙水溶液,当复合材料用量为0.4g,甲基橙溶液的pH 为6.0,温度为40℃,甲基橙初始浓度为10mg/L,降解时间为2.5h时,甲基橙的降解率最高可达98.43%。

Abstract: Silver carbonate ultrafine powder was prepared with silver nitrate and sodium carbonate Under the condition of ultrasonic dispersion,and polypyrrole - silver carbonate composites were sythsized with ammonium persulfate as the oxidant in situ polymerization. The performance of the composites were detected with IR ,XRD and Laser particle size analyzer. Methyl orange was degraded with the composites as the catalyst under simulated natural light. When the dosage of the composites was 0.4g,the initial concentration of methyl orange solution was 10mg/L,the degradation time was 2.5h,the pH value of methyl orange solution was 6.0,and temperature was 40℃,the degradation rate of methyl orange was up to 98.43%.

Key words: polypyrrole, silver carbonate, composite materials, photocatalytic degradation, methyl orange, degradation rate
