What is platinised asbestos?

Platinized asbestos is a material consisting of asbestos fibers coated with a thin layer of platinum. It used to be widely used as a catalyst in chemical reactions, particularly in the petroleum industry. However, due to potential health risks associated with asbestos fibers and the availability of alternative catalysts, the use of platinized asbestos has been discontinued, and safer substitutes are now commonly employed.
