摘要
An X-ray photoelectron spectroscopy study of supported tungsten oxide has indicated that calcination of WO3γ-Al2O3 leads to formation of tungstate. Proof has been obtained that WO3γ-Al2O3 cannot be appreciably reduced in hydrogen at 550 °C, whereas WO3SiO2 is reduced to lower valence states and unsupported WO3 is completely reduced to tungsten metal under these conditions.
