Abstract: Solar interfacial evaporation is a technology of efficient utilization of solar energy proposed in recent years. Solar evaporator is the key component of solar interfacial evaporation system. The antibacterial performance of solar evaporator plays an important role in seawater desalination. In this review,the antibacterial materials and their antibacterial mechanism are introduced,and then the research progress and application of the antibacterial solar evaporators are summarized respectively. In addition,the prospect and future challenges of antibacterial solar evaporators are discussed,so as to provide reference for the follow-up research and development of antibacterial solar evaporators and their application in solar desalination.
