Figure 5. Superhydrophilic/superaerophobic electrocatalyst composed of the supported CoMoSx Chalcogel. (A) air-bubble contact angles under water (top) and static-water-droplet contact angles (bottom) for CoMoSx/NF, MoSx/NF, Pt/C, and NF; (B) images of bubbles released at the surface of NF, CoMoSx/NF, and Pt/C for HER at a current density of 200 mA·cm^-2; (C) and (D) overall water splitting polarization curves of four electrodes and catalytic stability of CoMoSx/NF.
