Abstract

Facile removal of adsorbed gas bubbles from electrode surfaces is crucial to realize efficient and stable energy conversion devices based on electrochemical gas evolution reactions. Conventional studies on bubble removal have limited applicability and scalability due to their reliance on complex and energy/time‐intensive processes. In this study, a simple and versatile method is reported to fabricate large‐area superaerophobic electrodes (up to 100 cm 2 ) for diverse gas evolution reactions using the gel‐like aerophobic surface system (GLASS). GLASS electrodes are readily and uniformly fabricated by simple spin‐coating and cross‐linking of polyallylamine on virtually any kinds of electrodes within 5 min under ambient conditions. Intrinsically hydrophilic gel overlayers with interconnected open pores allow the physical separation of bubble adhesion and catalytic active sites, reducing bubble adhesion strength, and promoting the removal of gas bubbles. As a result, GLASS electrodes exhibit greatly enhanced efficiency and stability for diverse gas evolution reactions, such as hydrogen evolution, hydrazine oxidation, and oxygen evolution reactions. This study provides deeper insights into understanding the effect of the hydrophilic microenvironment on gas evolution reactions and designing practical electrochemical devices.

  • Coating polyallylamine hydrochloride hydrogel onto Pt-coated Ni foil makes aerophobicity significantly better than pristine electrode due to hydrophilicity and open pore structure, with bubble adhesion force only 6.87 μN and bubble contact angle 154.61°; during HER the gel-coated electrode exhibits excellent catalytic activity and stability, with average detached bubble diameter only ~50 μm.

    “Furthermore, Kang from the same team as Jeon [183] coated polyallylamine hydrochloride (PAH) and gelled it onto the Pt-coated Ni foil (Fig. 16c). The hydrophilicity of PAH hydrogel itself, coupled with the open pore structure on the surface, makes the aerophobicity of the electrode coated with PAH hydrogel significantly better than that of the pristine electrode. The bubble adhesion force is only”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
