摘要:
 以煤基炭膜为基膜,采用三电极体系的电化学沉积策略制备了NiCoP/炭电催化膜。通过XRD、SEM、XPS与EDS对NiCoP/炭电催化膜的形貌、结构与元素含量进行了分析,并考察了电催化膜对溴甲酚绿的去除效果。结果表明,NiCoP催化剂均匀担载在煤基炭膜表面;当外加直流电压为2.5 V时,新型NiCoP/炭电催化膜对溴甲酚绿去除率维持在88.46%,表现出良好的染料废水处理性能与可重复使用性能
  A facile electrodeposition strategy with three-electrode system has been developed to fabricate NiCoP/CEM by using the coal-based conductive carbon membrane as the base membrane. The morphology, structural characterizations and element content were investigated by various techniques including XRD, SEM, XPS and EDS. Moreover, the removal performance of bromocresol green solution was also investigated. It could be found that the NiCoP catalyst was uniformly deposited on the surface of coal-based carbon membrane. When the applied voltage was 2.5 V, the removal rate of bromocresol green by the NiCoP/CEM was maintained at 88.46%, which indicated superior treatment performance and reusable performance.
