Heat and mass transfer in evaporation-induced hydrovoltaic generation
Evaporation-induced hydrovoltaic generation is an emerging energy conversion technology.When hydrophilic porous nanomaterials are immersed in water,water molecules interact with them to form a continuous flow of water within the nanochannels and carry ions with an electrical charge opposite to that of the nanochannel surface,and creating an electric potential difference at both ends of the channels.However,the low efficiency of hydrovoltaic generation remains a critical challenge.Herein,we analyze the mechanism of evaporation-driven hydrovoltaic generation.Accordingly,strategies to improve the energy conversion effectiveness and output electrical performance of evaporation-driven hydrovoltaic generation devices are summarized.Finally,we provide an outlook on the challenges and prospects regarding the development of this emerging technology.
