石墨烯负载TiO_2材料制备及其在黑臭河道治理中的运用
|
摘要
黑臭水体治理是目前国内很多城市面临的难题。本文在分析水体自然净化条件的制约因素基础上,介绍了石墨烯掺杂Ti O2(TiO2@GR)材料强化水体自净的基本原理和石墨烯材料的制备方法,对于各城市黑臭水体治理和水环境质量改善具有一定的指导作用。
The treatment of black and odorous water body is a problem faced by many cities in China. This paper is based on the analysis of the constraints of natural purification, and introduce the principle of enhanced purification by graphene based doped TiO2 along with preparing method of the material, which provide cities with certain guidance on treating black and odorous water bodies and improving water environment quality.
