摘要
光催化技术是一种新兴的环境保护技术,可用于处理水和空气中的有机和无机污染物。CeO_(2)光催化剂由于其高稳定性和强光吸收能力而备受关注。但是CeO_(2)对自然可见光的吸收很弱,光生电子反应受限,在光催化中不能直接利用可见光促进电荷分离,这限制了催化活性和效率。本文主要从CeO_(2)自身的基本性能、结构和基本原理出发,综述了通过负载、掺杂及半导体复合等方法改性CeO_(2)光催化剂的研究进展,并展望了这一领域的发展前景。
Photocatalytic technology is an emerging environmental protection technology that can be used to treat organic and inorganic pollutants in water and air.CeO_(2)photocatalysts have attracted much attention due to their high stability and strong light-absorption.However pure CeO_(2)can absorb only a quite small part of natural visible light,restraining its photo-induced electron generation reaction.In photocatalysis conditions,CeO_(2)cannot directly utilize visible light to promote charge separation,thereby limiting its catalytic activity and efficiency.Starting from the basic properties,structure,and principles of CeO_(2),this review summarizes the modification of CeO_(2)using methods such as loading,doping,and semiconductor hybridization,and discusses the future development prospect of this field.
