Direct electricity generation from water flow/evaporation, coined hydrovoltaic effect, has recently attracted intense interest as a facile approach to harvest green energy ubiquitous capillary flow or evaporation. However, the current device is inferior in output power efficiency compared other renewable devices. Slow evaporation rate and inefficient charge collection at electrodes are two fundamental drawbacks limiting efficiency. Here, we report bioinspired hierarchical porous fabric...
Nowadays, supercapacitors as energy storage devices have gradually attracted more attention. In this paper, a tailored "staggered reaction" strategy was employed to synthesize the N/S codoped hollow porous carbon nanospheres an electrode material for high-performance supercapacitors. This manner features appropriate involvement of solvent acetone in reaction within system, which enables sequential process obtain core–shell structure with different internal and external compositions....
