In order to establish the standardization of catalyst preparations by one of the reference catalyst project, we selected three kinds of supported metal oxide catalysts : molybdena-alumina, vanadia-titania and cobalt-alumina, all of which are appreciated to be important as environmental catalysts.Only catalyst composition was indicated as a common parameter, and project members were expected to prepare catalysts by their own methods and make their characterization from the standpoint of their own interest.By repeating discussions on the obtained results, we aimed to make clear the key factors on the catalyst preparations and their characterization. The method of impregnation, pH of impregnation solution, suface area of alumina, temperature and atomosphere of drying process, calcination temperature and so on were investigated extensively and intensively, and the effect of these conditions on catalyst performance were compared.Because this project was based on the cooperative research woks by many independent researchers, there were applied the wide variety of available inspection methods for characterization, including conventional ones to the newest surface science techniques, and the results were fed back to the improvement of catalyst preparations.Finally, the research were brought to a conclusion by introducing the concept of "impact index", which means a measure for the intensity of preparation conditions onto the catalyst efficiencies.All the results were published or are now in printing on several international journals as 16 papers.

为了通过参考催化剂项目之一建立催化剂制备的标准化，我们选择了三种负载型金属氧化物催化剂：氧化钒-氧化铝、氧化钒-氧化钛和钴-氧化铝，所有这些都被认为是重要的环境催化剂。和项目成员希望通过自己的方法制备催化剂，并从自己感兴趣的角度对其进行表征。通过重复讨论所获得的结果，目的是明确催化剂制备的关键因素及其表征。本研究对浸渍方法、浸渍液pH值、氧化铝表面积、干燥温度、气氛、焙烧温度等条件对催化剂性能的影响进行了广泛而深入的研究，由于本研究是多位独立研究人员合作研究的结果，因此采用了多种现有的表征方法，本论文的主要研究内容包括：催化剂的制备、催化剂的制备、催化剂性能的评价、催化剂制备工艺的改进等。
