Abstract

A simple modification of electrodes with hydrogel can facilitate hydrogen evolution reactions by readily eliminating gas bubbles.

  • Depositing M13 bacteriophages-assembled hydrogel onto a Pt electrode, due to large surface area and high porosity, allows generated H2 bubbles to quickly detach, achieving efficient HER; the number of bubbles generated by the gel-coated electrode with titer 1.5 × 1014 PFU mL−1 is significantly more than pristine Pt electrode.

    “Jeon et al. [181] innovatively deposited M13 bacteriophages-assembled hydrogel onto a Pt electrode. Based on the large surface area and high porosity of the hydrogel, the generated H2 bubbles can quickly detach from the electrode surface, thereby achieving efficient HER (Fig. 16b). From the bubble situation during the hydrogen evolution process, it can be found that the number of bubbles generated”

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.
