A new, more abundant catalyst to generate dihydrogen from water
Publication of the Chemistry Laboratory in the journal ACS Catalysis on November 9, 2023. Communication of CNRS Chemistry on November 27, 2023. Producing dihydrogen by electrolysis of water requires rare and therefore expensive catalysts. They could be replaced by another molybdenum-based catalyst, much more abundant but currently less efficient. Scientists are therefore trying to elucidate how it works, in order to improve its performance. A study by teams from the Chemistry Laboratory (CNRS/ENS de Lyon) and IFP Énergies nouvelles (IFPEN), published in ACS Catalysis . Amorphous MoS3 (a-MoS3) is an appealing low-cost catalyst for the hydrogen evolution reaction (HER), which is a promising process for electrocatalytic hydrogen generation.
