Synergizing Hydrogen Spillover and Deprotonation by the Internal Polarization Field in a MoS2/NiPS3 Vertical Heterostructure for Boosted Water Electrolysis

Advances in Materials, 2022
Hydrogen spillover (HSo) has emerged to upgrade the hydrogen evolution reaction (HER) activity of Pt‐support electrocatalysts, but it is not applicable to the deprotonated oxygen evolution reaction (OER).

Vapor Phase Water Electrolysis or Pocket Mediated Water Electrolysis?

Journal of The Electrochemical Society
In this article, we show that adventitious water/electrolyte coming from various processing steps can obscure the assessment of results for a fully vapor-fed water electrolyzer. A couple hundreds of μl per cm2 of water can sustain typical operating current densities of 10 mA cm−2 geo for tens of hours, thereby not reflecting the true ...
