Title: SELF-ASSEMBLING AND SELF-HEALING NANOPARTICLE-BASED CATALYST FILMS FOR ALKALINE ELECTROLYSERS
Abstract:
The invention provides self-assembling and self-healing nanoparticle-based catalyst films that can be formed on the electrodes of alkaline electrolysers. Notably, provided is an electrocatalytic device comprising an electrolytic cell divided into anode and cathode chambers by an exchange membrane, said anode and cathode chambers being provided with electrodes immersed in electrolytic suspensions, wherein the electrolytic suspensions comprise surface charged catalytic particles forming self-healing films on the electrodes, and the use of the device as electrolyser, preferably for electrolysis of water.
