The precious metal platinum has excellent catalytic properties and has long been regarded as an ideal PEMFC electrocatalyst. By regulating particle size, surface structure, dispersion, etc., platinum nanoparticles can achieve efficient and selective organic transformation reactions.

Advantages of platinum nanopowders as green catalysts
1. High efficiency: Nano platinum particles have high specific surface area and active sites, so they can achieve efficient catalytic reactions at low temperatures and low pressures. This reduces energy consumption and reaction waste production, making Pt nanoparticles ideal for green catalysis.
2. Recyclability: Compared with traditional catalysts, nano Pt powders have better stability and recyclability. They can be used again through simple separation and recycling, thereby reducing catalyst consumption and environmental pollution.
3. Activity and selectivity: The surface structure and composition of platinum(Pt) nanopowders can be controlled through surface modification and alloying, thereby adjusting the catalytic activity and selectivity of different reactions. This enables nano Pt particles to efficiently catalyze a variety of organic reactions and obtain good product selectivity.
