In terms of desalination of seawater,brackish water and recycling of industrial wastewater,utilization of high-efficiency water treatment technology is crucial in solving the problem of water resource shortage and water pollution.At present,the widely used membrane separation technologies are accompanied by large energy consumption,low thermal efficiency and secondary pollution.Therefore,new membrane separation technology has received widespread attention.Photothermal membrane distillation(PMD)technology has shown great potential in the fields of seawater desalination and water resource reuse due to its high thermal efficiency,low energy consumption,and zero discharge characteristics.Fundamental photothermal processes and PMD mechanism are briefly illustrated,this is followed by reviewing photothermal materials feasible for developing PMD membranes and the research progress of PMD system.Comprehensive discussion about PMD performance is reviewed in different fields.Finally,the current challenges,limitation and future perspectives of PMD process are emphasized with the aim of providing reference for future works.
