- W2783253796 abstract "This paper reports the performance of hydrogen evolution reaction (HER) electrocatalysts based on Pt thin film electrodes that are encapsulated by silicon oxide (SiOx) nanomembranes. This membrane-coated electrocatalyst (MCEC) architecture offers a promising approach to enhancing electrocatalyst stability while incorporating advanced catalytic functionalities such as poison resistance and tunable reaction selectivity. Herein, a room-temperature ultraviolet (UV) ozone synthesis process was used to systematically control the thickness of SiOx overlayers with nanoscale precision and evaluate their influence on the electrochemically active surface area (ECSA) and HER performance of the underlying Pt thin films. Through detailed characterization of the physical and electrochemical properties of the SiOx-encapsulated electrodes, it is shown that proton and H2 transport occur primarily through the SiOx coating such that the HER takes place at the buried Pt|SiOx interface. Increasing the thickness of the SiOx ove..." @default.
