Why platinum tops the volcano plot, and a cheaper catalyst that could take its place. Best Poster.

The work

Green hydrogen is made by splitting water with renewable electricity, and the reaction needs a catalyst. Platinum works best but is rare and expensive. Our team of three set out to explain why it works and what could replace it.

Technical University of Denmark · 2023 · Team of 3

What I did

  1. 01Measured how fast different catalysts broke down hydrogen peroxide in the lab, and modeled the reaction.
  2. 02Ranked catalysts on a volcano plot by how strongly they bind hydrogen, with platinum at the top.
  3. 03Proposed molybdenum disulfide as a cheaper replacement, heat-treated in hydrogen to give it more active sites.
