摘      要：Adsorbent-assisted air water harvesting(AWH)may help alleviate the current global freshwater scarcity ***,the weak sorption capacity of various adsorbents and the high energy required to release water are two long-standing ***,we propose a class of green and clean adsorbent,TpPa-1@LiCl composite,whose sorption capacity is greatly improved to 0.37 and 0.80 g g^(-1)under 30%and 90%relative humidity(RH),respectively,and which has excellent stability,showing only a slight decrease(0.79%)after 10 sorp-tion–desorption cycles(1400 min).This TpPa-1@LiCl composite can reach equilibrium within 2 h and undergo complete desorption in 30 min under air mass 1.5 G irradiation.A corresponding solar-driven AWH device can complete up to 4 sorption–desorption cycles per day,with each cycle capable of collecting 0.34 g g^(-1)water without additional energy input,which implies TpPa-1@LiCl composite has the potential for achieving sorption-assisted AWH with high efficiency and rapid cycling.
