Thermal properties and oxidation of adsorbed organic materials on alloyed noble metal colloids in low-middle temperature region

摘要

In this study, we investigated the syntheses of alloyed noble metal (Ag, Au, Pd) colloids and their thermal properties. Also oxidation of organic materials adsorbed on the alloy colloids in low-middle temperature region was investigated. These colloids which were synthesized with simultaneus reduction method had low crystallinity in room temperature, but alloying and crystalizing was achieved by heating. From the results of thermal analyssis, it was identified that alloying of colloids is related to their thermal properties.
