Electrocatalyst

A platinum cathode electrocatalyst's stability being measured by chemist Xiaoping Wang

An electrocatalyst is a catalyst that participates in electrochemical reactions. Electrocatalysts are a specific form of catalysts that function at electrode surfaces or, most commonly, may be the electrode surface itself. An electrocatalyst can be heterogeneous such as a platinized electrode.[1] Homogeneous electrocatalysts, which are soluble, assist in transferring electrons between the electrode and reactants, and/or facilitate an intermediate chemical transformation described by an overall half reaction.[2] Major challenges in electrocatalysts focus on fuel cells.[3][4]
