Analyses of Mechanochemical Reactions at the Boundary between Metal Oxide – Organic Fine Particles and Their Practical Application

Keio University, 3-14-1, Hiyoshi, Yokohama 223-8522 (Japan)

Starting from the colour change upon co-milling a white mixture comprising a metal oxide (MO) and organic solids (OS) with F or N, general features of the mechanochemical reactions at the boundaries between MO and OS were observed, characterized and discussed with the presence of various analytical results. Three parallel streams of the mechanochemical reactions upon co-milling are confirmed, i. e., i) an oxidative decomposition of the organic species, ii) formation of nanostructured carbon, and iii) incorporation of non-oxygen anionic species into oxides via a ligand exchange. In the case of wet milling, complex ion formation in a liquid phase is sandwiched. Case studies were focused on TiO2 as MO and polytetrafluoroethylene (PTFE) or glycine (Gly) as OS.
