%10 platinum on activated carbon

Platinum carbon catalyst belongs to noble metal catalyst with black powder appearance and molecular weight of 195.08. Platinum carbon catalyst is a kind of carrier catalyst which supports platinum onto activated carbon. Can be used in pharmaceutical, electronic and other fields, the application is more extensive. The platinum content ranged from 0.5% to 20%.

At present, carbon platinum catalysts with high load capacity are one of the key materials for proton exchange membrane fuel cells. The size distribution of pt nanoparticles and the content of impurities have great influence on the electrocatalytic performance and operational stability of the catalysts. When the particle size of Pt in the catalyst is 2-5nm, the particle size distribution is narrow, the particle size distribution is uniform on the carbon, and the content of harmful impurities (such as Cl) in the catalyst is small, the catalyst has better activity and stability. Particle size distribution and impurity content control of Pt metal particles in carbon-based platinum catalysts are the difficulties and emphases in the preparation of catalysts.

Platinum carbon catalysts are mainly used in the following aspects:

1.Organic synthesis: dehydrogenation, aromatic ring hydrogenation, hydrogen peroxide decomposition, gas purification;

2. Platinum carbon is used in the combination reaction of hydrogen and oxygen to purify hydrogen from oxygen, argon, nitrogen, carbon dioxide, air and helium;

3. Platinum carbon is used in the combination reaction of oxygen and carbon tetrachloride to purify oxygen from nitrogen;

4. Platinum carbon is used for the combination reaction of hydrocarbons and oxygen, and the hydrocarbon compounds are purified from oxygen, nitrogen, carbon dioxide, air, helium and argon;

5. Platinum carbon is used for the combination reaction of carbon monoxide and oxygen to purify carbon monoxide from carbon dioxide, nitrogen and air.

Platinum carbon has high selectivity, activity and long life. The reaction can be carried out at low temperature, low pressure or even normal temperature and pressure. It can be recycled, purified and reprocessed.
