S. Meijers et al., IR SPECTROSCOPIC STUDY OF THE SKELETAL ISOMERIZATION OF BUTENE BY ALUMINA-SUPPORTED TUNGSTEN-OXIDE CATALYSTS, Journal of catalysis, 156(1), 1995, pp. 147-153
The surface properties of supported tungsten oxide catalysts, pure tun
gsten oxide, and pure alumina were studied by IR spectroscopy, using p
yridine and carbon monoxide as probes. The interaction of these cataly
sts with n-butenes, molecules which are isomerised selectively by the
catalysts to isobutene, has also been studied by IR spectroscopy. A co
rrelation is found between the catalytic properties of the catalysts a
nd the strength and nature of the acidic sites found on their surface.
