Formation and immobilization of silver nanoparticles onto chromia surface by novel preparation route involving polyol process

초록

Silver nanoparticles were formed and immobilized onto the chromia surface by novel preparation route involving polyol process for the first time. (3-Mercaptopropyl) trimethoxy silane (MPTMS) was employed as a chemical protocol to make a binding between silver nanoparticle and chromia surface. UV-vis absorption spectroscopy, TEM observation and EDS analysis revealed that silver nanoparticles with a size of similar to 50 nm in diameter were formed and immobilized onto the surface of chromia particles with an average size of 210 run. It is thought that this novel preparation route can be extended to the preparation of various metal-inorganic heterogeneous composite particles.
