Abstract:Low-Ir
electrocatalysts are crucial for developing large-scale
polymer-electrolyte-membrane water electrolysis (PEMWE) facilities,
which are necessary to advance the hydrogen economy. However, the
performance and durability of low-Ir electrocatalysts are unsatisfactory.
To address this issue, we prepared selenium-modified Ir nanoparticles
on high-crystalline-carbon (HCC) supports. The introduction of HCC
supports effectively reduced Ir usage, and Se incorporation mitigated
Ir degradation. Se nucleophiles suppr… Show more
