An Electrocatalyst with Dense Single-Atom Platinum Sites for Hydrogen Evolution Reaction
Platinum (Pt) is widely used in proton exchange membrane water electrolyzers (PEMWEs) for hydrogen (H2) production due to its intrinsically high activity for the cathodic hydrogen evolution reaction (HER). However, its usage is expected to be further reduced to improve the H2 cost-competitiveness. Herein, enabled by...
