摘要
光催化还原技术越来越得到人们的认可。文章综述了TiO2光催化还原技术在废水中重金属离子处理方面的应用,从重金属离子的光催化还原机理、反应驱动力、光催化剂的失活与再生以及各种光催化还原重金属的影响因素等方面,阐述了重金属离子的光催化还原新进展。
Photocatalytic reduction of heavy metal ions in wastewater has been widely studied as a rapidly expanding technology for wastewater treatment. Application of photocatalytic technology in heavy metal ions was reviewed, and recent studies on photocatalytic reduction of heavy metal ions were also described including mechanism, driving force of reduction, deactivation and regeneration of photocatalyst as well as impact factors.
