主 题:solar steam generation photo-electro-thermal effect salt resistance desalination fabric
摘 要:Solar-driven steam generation is a practical strategy to harness solar energy for desalination and production of clean water with a minimized carbon ***,this strategy suffers from a low evaporation rate under weak illumination on cloudy days or at ***,we present a fabric-based all-weather-available photo-electrothermal steam generator(P/ET-SG)capable of regulating the surface temperature and evaporation rate by the coupling effect of photo-thermal and electro-thermal heating depending on the light *** unprecedented high surface temperature of 52℃ in the wet state and an evaporation rate of 2.61 kg m^(-2) h^(-1) were achieved by the P/ET-SG under 1 sun with only 1 V input voltage owing to the uniform heat distribution and the coupled electro-thermal *** oneway fluidic design of the P/ET-SG effectively prevented salt precipitation during continuous desalination in 24 h and was able to remove salt granules from the evaporation ***,the P/ET-SG demonstrated a high evaporation rate of 2.58 kg m^(-2) h^(-1) in the purification of concentrated saline water and dye-contaminated water with high efficiency(99.9%).This study offers new thoughts for the design of allweather-available solar steam generators with high efficiency and makes a step forward towards fast purification of concentrated saline water and wastewater.
