Used primarily as a catalyst in organic synthesis, especially for hydrogenation reactions. It facilitates the addition of hydrogen to unsaturated compounds such as alkenes, alkynes, and aromatic rings under mild conditions. Commonly employed in the reduction of nitro groups, nitriles, and carbonyl functionalities. Also utilized in fuel cell research and electrochemical applications due to its conductive and catalytic properties. Shows activity in selective oxidation processes when activated in situ. Often preferred for its stability and reusability in heterogeneous catalysis.
