摘　　要：高效、稳定的催化剂的开发是催化氧化净化VOCs技术所必须要解决的核心问题。杂原子掺杂作为一种简单、高效的调控Co_(3)O_(4)催化剂物理化学性质的手段,受到越来越多的关注。以Cu对Co_(3)O_(4)进行了掺杂,一系列的表征与活性评价的结果表明,适量Cu掺杂大幅增加催化剂的比表面积,改善催化剂的氧化还原性能,从而增强其催化活性。Heteroatom doping has attracted more and more attention as a simple and efficient means to tune the physicochemical properties of Co_(3)O_(4)catalysts.In this paper,Co3O was doped with Cu.The results of a series of characterization and activity evaluation showed that the appropriate doping amount of Cu greatly increased the specific surface area of the catalyst,improved the redox performance of the catalyst,which significantly enhanced the catalytic activity of the obtained Cu_(x)Co_(3-x)O_(4)catalysts.
