Researchers from the University of Toronto’s Faculty of Applied Science & Engineering and Fujitsu have applied quantum-inspired computing to find the promising, previously unexplored chemical family of Ru-Cr-Mn-Sb-O2 as acidic oxygen evolution reaction catalysts for hydrogen production.
The best catalyst shows a mass activity eight times higher than state-of-the-art RuO2 and maintains performance for 180 h. A paper on their work appears in the journal Matter.

Scaling up the production of what we call green hydrogen is a priority for researchers around the world because it offers a carbon-free way to store electricity from any source. This work provides proof-of-concept for a new approach to overcoming one of the key remaining challenges, which is the lack of highly active catalyst materials to speed up the critical reactions.—Ted Sargent, senior…
