摘　　要：目的概述过渡金属单氧化物(FeO,CoO和NiO)光催化剂的研究进展,旨在从机理层面上更好地认识这类催化剂,使之为工业生产和生活服务。方法参考国内外相关文献32篇,对过渡金属单氧化物(FeO,CoO和NiO)光催化剂的研究进展进行综述。结果从FeO,CoO,NiO及其掺杂物的结构、电子性质和其光催化性质几方面入手,对前人的研究工作进行了简要概述,并指出了其中存在的一些问题。结论过渡金属单氧化物(FeO,CoO和NiO)作为一类重要的光催化剂,有化学性质稳定、低成本、无毒等优点,但是由于其禁带宽度较大,对光的利用率低;催化剂很容易发生团聚,导致表面积降低而失活;对其催化机理的研究有待进一步深入。Purposes—To better understand the photocatalyst of transition metal monoxides(such as FeO,CoO and NiO)from the perspective of mechanism level by summarizing the research progress of this kind of catalyst and make them serve for our industrial production and life.Methods—The research progress of transition metal monoxides photocatalysts is reviewed with reference to 32 papers from home and abroad.Results—The previous relevant studies was summed up by proceeding with the doped structure,electronic properties and photocatalytic performance of FeO,CoO and NiO,and the problems were pointed out herein.Conclusions—Transition metal monoxides(FeO,CoO and NiO)have become a significant class of photocatalysts due to their chemical stability,low cost,non-toxic and other advantages,but their broad band gaps,light utilization ineffectiveness and easy aggregation often reduce surface area and deactivate,so a further study on catalytic mechanism is necessary.
