Research progress of nanotechnology for the treatment of crude oil pollutants

本文综述了纳米TiO_2光催化技术对石油污染物中多种具有代表性的污染物光催化降解研究状况及其在石油污染处理应用中的研究概况,以及目前尚存在的一些问题,列举了近些年来关于利用光催化技术处理石油污染研究的部分成果,认为在未来的研究中应该集中在反应机理、光响应范围和量子效率高的催化剂制备等方面。

The paper deals with the applications of nanocrystalline TiO_2 photocatalysis for degradation of several typical crude oil pollutants. The recent developments and problems of nanocrystalline TiO_2 photocatalysis and its application prospects for the treatment of crude oil pollutants are introduced. The main achievements in the studies of photocatalysis during the recent years were particularized. It is suggested that attention of the future investigation should focus on the three aspects as follow i.e. comprehension for photocatalytic mechanism, synthesis or preparation of novel photocatalyst with wide response to light and high photo quantum efficiency.
