= Electrocatalyst
{wiki=Electrocatalyst}
An electrocatalyst is a material that facilitates electrochemical reactions by lowering the activation energy required for the reactions to occur. These reactions typically take place at the interface of an electrode and an electrolyte in electrochemical cells, such as fuel cells, batteries, and electrolyzers. Electrocatalysts play a critical role in processes like hydrogen production (through water splitting), oxygen reduction, and carbon dioxide reduction.
