Abstract

The titration by means of hydrogen or deuterium at 100 °C of oxygen preadsorbed on a supported palladium catalyst has been used to measure the dispersion of the palladium. Results agree with those obtained by X-ray line broadening and chemisorption of oxygen or carbon monoxide. The titration, which is done at pressures where a negligible amount of bulk hydride forms, has distinct advantages over the other methods.

测定负载钯表面积的氢氧滴定法

在负载型钯催化剂上预吸附100°C的氧，用氢或氘滴定法测定钯的分散。结果与x射线谱线展宽和氧或一氧化碳化学吸附的结果一致。这种滴定是在可忽略不计的体积氢化物形成的压力下进行的，与其他方法相比具有明显的优点。

期刊介绍： The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes. The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods. The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
