Some Environmentally Relevant Reactions of Cerium Oxide

摘要: Reactive forms of cerium oxide were prepared by a thermal decomposition various precursors, namely carbonates, oxalates and citrates, commercially available nanocrystalline (nanoceria) was involved in the study for comparison. Scanning electron microscopy (SEM) x-ray diffraction analysis (XRD) used to examine morphology crystallinity samples, respectively, whereas Brunauer-Emmett-Teller (BET) method nitrogen adsorption determine surface areas. Interactions with some phosphorus-containing compounds investigated. Some examined especially those annealing from carbonate exhibited an outstanding ability destroy highly toxic organophosphates, such as pesticides (parathion methyl), or nerve agents (soman, VX). There identified relations between degradation efficiency oxides their crystallinity. It also shown that is able one widely flame retardants - triphenyl phosphate. A phosphatase-mimetic activity aid standardized phosphatase test.
