Sino-Science Hydrogen Platinum Catalyst Hydrogen Fuel Cell High-Performance Materials

Specification

Description

Platinum-carbon catalyst is currently one of the key materials of the proton exchange membrane fuel cell (PEMFC). Commercial fuel cell platinum-carbon catalysts are generally platinum particles with a particle size of 2-5 nm distributed on a carbon support with excellent electrical conductivity, high specific surface area, moderate porosity and resistance to electrochemical corrosion. According to needs, the platinum loading varies from 20% to 70%; the anode catalyst loading is relatively low, and the cathode oxygen reduction catalyst generally has a loading greater than 50%.

Platinum on carbon is used for catalytic hydrogenations in organic synthesis. Examples include carbonyl reduction, nitro compound reduction, secondary amine production via nitrile reduction, and the production of saturated heterocycles from their respective aromatic compound precursors.
