Carbon supported platinum nanoparticles were synthesized by microwave assisted heating ethylene glycol solution of H2PtCl6 with different pH values in the presence of XC-72 carbon or carbon nanotubes supports.

Based on the characteristics of ionic liquid,platinum nanoparticles were prepared without using polymer as protecting agent,and a bifunctional catalyst with metallic and acidic active sites was prepared simultaneously.

Template-free fabrication of macroporous carbon materials with Pt nanoparticles;

TEM imaging showed that microwave-prepared Pt nanoparticles were very uniform in size, with an average size of 3.

The Pt nanoparticles in diameter of 10 nm were prepared by microwave high-pressure procedure,using sodium citrate as a reducer to reduce Pt(Ⅳ)to small Pt nanoparticle and polyacrylamide(PAM)as a stabilizer for the particles.

Part IThe Pt nanoparticle is an important material of the scanning tunnel microscope (STM) nanoprobe and a preferable catalyst.
