Microbial pathogenic contaminations have world widely represented a serious health hazard to humans. Viruses, as a member of microbial contaminants, seriously threaten human health due to their high environmental resistance, having small sizes, and causing an extensive range of diseases. Therefore, selecting an appropriate technology to remove viral contaminants from the air, water, and foods is of prominent significance. Traditional methods for viral disinfection have not proven to be highly practical and effective because they need high energy resources and operational expenses. In recent years, semiconductor-based photocatalysis has attracted more attention in the field of microorganism inactivation due to its outstanding performance and mild reaction conditions. Therefore, this review primarily concentrates on the recent development in viral inactivation/disinfection by heterogeneous photocatalysts. Moreover, the photocatalytic viral inactivation of waterborne, airborne, and foodborne viruses is discussed. Given the appealing merits of heterogeneous photocatalytic disinfection of viruses, there is no doubt that this technology will be an impressively active research field and a source of comfort and confidence to humans in battling against viruses.
微生物污染对人类的健康构成了严重威胁，在世界范围内都具有重要意义。病毒作为微生物污染物的一种，由于其环境抗性高、体积小、能引起广泛的疾病，严重威胁着人类的健康。因此，选择一种合适的技术来去除空气、水和食物中的病毒污染物具有重要意义。传统的病毒消毒方法由于需要高能源资源和运营费用，因此证明并不十分实用和有效。近年来，基于半导体的光催化技术因其出色的性能和温和的反应条件，在微生物灭活领域引起了更多的关注。因此，本综述主要集中在异质光催化剂对病毒失活/消毒的最新发展。此外，还讨论了水传播、空气传播和食源传播病毒的光催化病毒灭活。鉴于异质光催化消毒病毒具有吸引人的优点，毫无疑问，这项技术将成为一个非常活跃的研究领域，为人类对抗病毒提供安慰和信心。
