Platinum Black Powder is a highly effective catalyst in many chemical reactions. Its high surface area and porous structure provide numerous active sites for catalytic reactions. It is often employed in hydrogenation, oxidation, and dehydrogenation reactions. This finds applications in the chemical industry, petroleum refining, pharmaceuticals, and environmental processes. Platinum Black Powder is extensively used as a catalyst in proton exchange membrane fuel cells (PEMFCs). It serves as the catalyst material at the cathode, facilitating the oxygen reduction reaction (ORR) during electricity generation.
