| 摘 要： | 以Bi(NO3)3.5H2O、NH4VO3和Co(H3CO2)2.4H2O为原料,采用水热法合成光催化剂Co-BiVO4,并对其进行了XRD、UV-visDRS表征。以模拟含酚废水为目标物,以不同的催化剂、光源、催化剂的量及通气量为考察对象,研究了Co-BiVO4催化剂的光催化性能。结果表明,Co-BiVO4在光源为金卤灯(400 W),前驱物pH=7,光照时间60 min左右,催化剂用量1.0 mg/mL,通气量为200 mL/min的条件下,对模拟含酚废水的降解率可达到95%以上。

| Abstract: | A visible-light-induced photocatalyst Co-BiVO4 was prepared by hydrothermal method,using Bi（NO3）3·5H2O、NH4VO3 and Co（H3CO2）2·4H2O as reactants.The as-prepared samples were characterized by XRD and UV.The photocatalytical activity was studied by degrading volatile phenol in wastewater.The results show that,the degradation rate of Co-BiVO4 to volatile phenol in wastewater can reach 95% above,under the optimal conditions,which is 1.0mg/mL of catalyst,200mL/min of air,pH=7 of precursors,400w of Metal Halide light. |
