使用吡啶和一氧化碳作为探针，通过红外光谱研究了负载型氧化钨催化剂、纯氧化钨和纯氧化铝的表面性质。这些催化剂与正丁烯（通过催化剂选择性异构化为异丁烯的分子）的相互作用也通过红外光谱法进行了研究。催化剂的催化性能与其表面酸性位点的强度和性质之间存在相关性。
The surface properties of supported tungsten oxide catalysts, pure tungsten oxide, and pure alumina were studied by IR spectroscopy, using pyridine and carbon monoxide as probes. The interaction of these catalysts with n-butenes, molecules which are isomerised selectively by the catalysts to isobutene, has also been studied by IR spectroscopy. A correlation is found between the catalytic properties of the catalysts and the strength and nature of the acidic sites found on their surface.
