Abstract:

A NiCoFeCrZn-based HEO was directly synthesized over carbon cloth via one step CO₂ laser irradiation of metal salts. The binder-free HEO-based electrode (HEO/CC) exhibits excellent HER activity under alkaline conditions, achieving low overpotentials of 52 mV at 10 mA cm^-2, and maintains stable performance over 14 days at a higher current density.

Catalysis

Catalysis

The presence of a catalyst affects the rate of a chemical reaction. A catalyst is a substance that can increase the reaction rate without being consumed during the process. A basic comprehension of a catalysts’ role during chemical reactions can be understood from the concept of reaction mechanisms and energy diagrams.
