Abstract：

Due to the large latent heat of vaporization, water evaporation process involves with large amount of energy exchange, thus has been utilized as an efficient way to enhance thermal energy transfer in many important daily and industrial applications, such as transpiration cooling and heat pipe. Here we present that water evaporation from the porous carbon film, the lowest-cost nanostructured carbon material, can reliably generate voltage up to 1 V under ambient conditions, which is large enough for powering existing electronic devices directly. The output performance of the device can be easily scaled up and used to power low-power consumption electronic devices or for energy storage. Furthermore, the device was successfully used without electric storage as a direct power source for electrodeposition and organic dye degradation.
