Sino-Science Hydrogen Platinum Black Catalyst High-Performance Materials

Specification

Description

Platinum black, a very fine black precious metal platinum powder, element symbol is Pt, atomic weight is 195.05, apparent density is between 15.8 and 17.6, platinum content is more than 99%. Platinum black is insoluble in inorganic or organic acids, but soluble in aqua regia. Generally, it is accumulated on the surface of asbestos or porous materials. For example, asbestos is immersed in chloroplatinic acid or chloroplatinic acid solution, and platinum asbestos can be obtained by burning it out. It can adsorb a large amount of hydrogen at 0 °C. Platinum black or platinum asbestos can be used as a catalyst in many gases. Electrolytic chloroplatinic acid can also be electroplated with platinum black to adsorb hydrogen on the surface of gold or platinum electrodes, so it is also commonly used in hydrogen electrodes or other gas electrodes.
