Recent progress on the long‐term stability of hydrogen evolution reaction electrocatalysts Abstract Developing new methodologies to produce clean and renewable energy resources is pivotal for carbon‐neutral initiatives. Hydrogen (H 2 ) is considered as an ideal energy resource due to its nontoxic, pollution‐free, high utilization rate, and high calorific combustion value. Electrolysis of water driven by the electricity generated from renewable and clean energy sources (e.g., solar energy, wind ...
