据中国科学院通报,近期,该院合肥物质科学研究院技术生物与农业工程研究所研究员吴正岩课题组利用电子束辐照技术制备出新型纳米复合型光催化剂,该催化剂可以在可见光照射下快速降解除草剂。该工作已被《化学工程杂志》(Chemical Engineering Journa)l接收发表。随着农业的快速发展,除草剂用量与日俱增,不仅对环境造成巨大压力,而且危害人畜健康。光催化降解法是目前处理除草剂的常用方法之一,但由于现有光催化剂存在制备工艺复杂、紫外激发、成本高、效率低等缺点,成为限制除草剂光催化降解技术发展的瓶颈,亟
According to the Chinese Academy of Sciences Bulletin, recently, the Institute of Hefei Institutes of Physical Science and Technology, Institute of Biological and Agricultural Engineering researcher Wu Zhengyan team using electron beam irradiation technology to prepare a new nanocomposite photocatalyst, the catalyst can quickly degrade the weeds in the visible light irradiation Agent. This work has been published by Chemical Engineering Journa. With the rapid development of agriculture, the use of herbicides is increasing day by day, which not only exerts tremendous pressure on the environment, but also endangers the health of humans and livestock. Photocatalytic degradation is one of the common methods for the treatment of herbicides. However, the existing photocatalysts have many disadvantages, such as complex preparation, UV excitation, high cost and low efficiency, which become the bottleneck restricting the development of the herbicide photocatalytic degradation technology.
