Abstract
Abstract A combination of in situ high-voltage electron microscopy (HVEM), X-ray/ electron diffraction methods, X-ray and electron probe microanalysis as well as high-resolution phase contrast lattice imaging (<2 AS resolution) microscopy techniques has been used to investigate the reaction properties of an industrial tellurium-molybdenum oxide catalyst system used, for example, in the ammoxidation of propylene to produce organic chemicals such as acrylonitrile, acrolein and other hydrocarbon conversion reactions. In situ electron microscopy experiments conducted on the catalysts in reducing/oxidizing gaseous environments with pressures comparable to those used in the commercial reactions have revealed degradation products which have been analysed by high-resolution microscopy. In this industrial system at typical catalyst operating temperatures no evidence for crystallographic shear planes has been obtained and the implications concerning the role of such extended defects in industrial catalytic reaction...
