Highly-efficient and salt-resistant CsxWO3@g-C3N4/PVDF fiber membranes for interfacial water evaporation, desalination, and sewage treatment

In this work, cesium tungsten oxide/graphitic carbon nitride (Cs0.32WO3@g-C3N4) hybrids were successfully synthesized using a facile solvothermal method. The hybrids were incorporated into PVDF and electrospun into Cs0.32WO3@g-C3N4/PVDF fiber membranes. Water evaporation, desalination, and sewage treatment were studied using the photothermal fiber membranes. The experimental results showed that the highest photothermal conversion could be...
