WebOne of the biggest areas of interest for carbons produced by catalytic graphitization is as electrocatalysts for the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells. 46 The ORR occurs at the cathode, where oxygen is reduced by electrons and protons to produce water. WebGraphitization is a microstructural change that occurs in carbon or low-alloy steels exposed to temperatures of about 425–550°C for several thousand hours. Applications involving prolonged exposure at this temperature range, such as economizer tubing, high-pressure steam pipes, and other components, are prone to this form of embrittlement.
