Haolan Xu/Yingying Zhang/Li Yu: Efficient seawater desalination technology – a new strategy for building photothermal interface evaporation!

On March 8, 2023, Professor Haolan Xu of the University of South Australia, Professor Yingying Zhang of Tsinghua University and Associate Professor Yu Li of Shenzhen University of Technology hosted a new journal at Tsinghua UniversityNano Research Energy ( a recent review titled “Recent strategies for constructing efficient interfacial solar evaporation systems.”

Developments in recent yearsInterface photothermal evaporation (ISE) is a desalination technology with extremely high energy conversion efficiency and environmental friendliness. This technology promises to easeGlobal freshwater shortagesproblem. So far, many new photothermal materials and evaporators with efficient solar thermal conversion efficiency have been developed, prepared and applied to ISE. With reasonable design, photothermal evaporators can achieve excellenceEnergy management, thereby reducing energy loss and extracting additional energy from the environment, effectively using and recovering energy in the system to improve photothermal evaporation efficiency and freshwater production. In addition to this, by introducingMolecular engineeringRegulating the state of the water and thus reducing the enthalpy of evaporation has also proven to be a very effective strategy for improving ISE.

In view of this, the University of South AustraliaXu HaolanProfessor, Tsinghua UniversityZhang YingyingProfessor and Shenzhen University of TechnologyResidual profitAssociate Professor inNano Research EnergyA recent review entitled “Recent strategies for constructing efficient interfacial solar evaporation systems” was published to summarize and look aheadHow to design and prepare efficient photothermal evaporation systems。 The article begins with a systematic summary ofImprove actual photothermal evaporation performancepathways; The two-dimensional and three-dimensional evaporation systems in the evaporation process at the photothermal interface were analyzed and comparedEnergy relationship, and pointed out the main differences. On this basis, the two-dimensional and three-dimensional evaporators and evaporation systems are sorted outDesign ideasandEnergy management strategies。 The review also specifically summarizes the main strategies and methods for reducing the enthalpy of evaporation in water. Finally the author is interested in the existingEvaporation systemandEvaporator designThis paper summarizes and looks forward to the future research direction in this field and the problems that need to be solved for applications, which provides valuable guidance for building high-performance ISE and realizing practical applications.
