Description
The extremely fine powder of metallic platinum is black, so it is called platinum black. The apparent density is 15.8-17.6. Soluble in aqua regia. Generally, it accumulates on the surface of asbestos or other porous materials. For example, asbestos is immersed in chloroplatinic acid or ammonium chloroplatinate solution, taken out and burned to obtain platinum wool. Platinum black and platinum (asbestos) can absorb a large amount of hydrogen, oxygen and other gases, and can be used as catalysts in many gas reactions. For example, the oxidation of ammonia. Electrolysis of chloroplatinic acid can also make platinum black plated on the surface of platinum or gold electrodes, which are often used as hydrogen electrodes or other gas electrodes in electrochemistry. Platinum black can be made by adding zinc or magnesium to platinum salt solution.
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.
