Platinum (10% Pt black powder) is a high-purity, finely divided catalyst, often supported on carbon, widely used in laboratory organic synthesis for heterogeneous catalysis. It excels in hydrogenation reactions, reducing alkenes, alkynes, nitro compounds, aromatic rings, and carbonyl groups to alcohols or amines. Its high surface area provides superior activity for hydrogenolysis, debenzylation, and selective reductions in pharmaceutical and fine chemical production. This form is also employed in electrocatalysis, fuel cell research, and analytical chemistry applications requiring efficient platinum catalysis.
