Surface wettability engineering: CoSx-Ni3S2 nanoarray electrode for improving overall water splitting

Besides the development of effective catalysts, surface property of the electrode is also crucial in electrocatalytic hydrogen evolution. Herein, a nanosheet array electrode of CoSx-Ni3S2/NF was designed by a facile hydrothermal process. Particularly, the obtained electrode was endowed with superhydrophilicity and superaerophobicity, which not only facilitates to the exposure of active sites, but also alleviates the “bubble shielding effect” for...
