BiVO4纳米多孔纤维光催化污水处理研究

Research on BiVO4 Nanoporous Fiber Photocatalytic Wastewater Treatment

水污染已经严重地影响了人们的日常生活,开发一种新型的、利用光催化材料技术来进行污水处理,是目前的研究热点。深圳双瑞环保能源科技有限公司和重庆文理学院通过联合研发,利用静电纺丝法成功地制备出了BiVO4复合光催化剂。研究结果表明,改性后的BiVO4多孔纳米纤维具有明显增强的可见光光催化活性。在可见光照射下,可在60分钟内降解78.1%的亚甲基蓝。这种制备Bi/BiVO4多孔纳米纤维的方法简单、稳定,可推广应用于工业化的污水处理中。

Water pollution has seriously affected people’s daily life.The development of a new type of technology that uses photocatalytic materials for sewage treatment is a current research hotspot.Shenzhen Shuangrui Environmental Energy Technology Co.,Ltd.and Chongqing University of Arts and Sciences have successfully prepared BiVO4 composite photocatalysts through joint research and development using electrospinning.The research results show that the modified BiVO4 porous nanofibers have significantly enhanced visible light photocatalytic activity.Under visible light irradiation,78.1%of Methylene blue can be degraded within 60 minutes.This method for preparing Bi/BiVO4 porous nanofibers is simple and stable,and can be promoted and applied to industrial sewage treatment.
