A combined environmental scanning electron microscopy and Raman microscopy study of methanol oxidation on silver(I) oxide

摘要

The techniques of environmental scanning electron microscopy (ESEM) and Raman microscopy have been used to respectively elucidate the morphological changes and nature of the adsorbed species on silver(I) oxide powder, during methanol oxidation condi- tions. Heating Ag_2O in either water vapour or oxygen resulted firstly in the decomposition of silver(I) oxide to polycrystalline silver at 578 K followd by sintering of the particles at higher temperature.
