摘要
本文介绍了二氧化碳和水蒸气之间催化同位素交换反应催化剂活性的研究结果。这些样品是在铁、钴和镍氧化物的基础上合成的，并以γ-氧化铝为载体。利用扫描电子显微镜、X 射线荧光分析和低温氮吸附对所获样品的结构研究结果进行了分析，以确定比表面积和孔隙率。结果表明，氧化铝支撑的氧化镍具有最高的催化活性（观察到的速率常数 k = 5.49 ± 0.36 s-1）。
New Catalysts for Chemical Isotope Exchange between Water and Carbon Dioxide
The results of a study of the activity of catalysts for the reaction of catalytic isotope exchange between carbon dioxide and water vapor are presented. The samples were synthesized on the basis of iron, cobalt and nickel oxides, applied to a carrier—γ-aluminum oxide. The results of structural studies of the obtained samples were analyzed using scanning electron microscopy, X-ray fluorescence analysis, and low-temperature nitrogen adsorption to determine the specific surface area and porosity. It was concluded that nickel oxide supported on aluminum oxide has the highest catalytic activity (observed rate constant k = 5.49 ± 0.36 s–1).
