    Water Splitting

## Description

- description: In electrochemical hydrogen evolution reaction (HER), the produced
    hydrogen gas bubbles often adhered to the electrode surface—and blocked the active
    catalytic site. While different catalysts were developed to improve the catalytic
    performance of HER, the design of a durable and universal approach for minimizing
    the force of nucleated hydrogen gas-bubble adhesion to prevent blockage of electrocatalytic
    sites because of bubbles-adhesion—is unprecedented. Generally, buoyancy should
    outweigh the capillary force to remove nucleated bubbles, which means these forces
    ratio, Eötvös number Eo > 1. Herein, we report a chemically reactive multilayer
    coating on an electrode to chemically modulate the adhesion force of nucleated
    gas-bubble on the electrode. A dual modified coating on Ni-foam provided a non-adhesive
    superaerophobicity with nucleated bubble adhesion force of 4.6 ± 0.3 μN—and displayed
    superior HER performance with lower overpotential (333 to 250 mV) at 100 mA cm-2
    with respect to bare Ni-foam. The chemically-modulated low bubble-adhesion facilitated
    the early removal of nucleated tiny hydrogen gas bubbles with a minimum size of
    0.64 mm and Eo = 0.05 to keep catalytic sites available for superior electrochemical
    HER. Such a positive impact of the prepared coating was also noted for various
    other electrodes.
