钌硫化合物的组成测定和氢还原动力学研究

Determination of Composition and Investigation of Hydrogen Reductive Dynamics of Ruthenium-Sulfides

用静态和动态库仑滴定法分别对元素合成的硫化钌和两种湿法沉淀的硫化钌进行了研究,确定了硫化钌的组成和分子式,阐明了化合物在高温被氢还原的动力学特性,根据研究结果,推测出非晶态的原始Ru_3S_3·10H_2O具有RuS·RuS_2·10H_2O的结构。

The ruthenium sulfides obtained by the element synthesis and two wet methods were studied by using static and dynamic coulometric titration method. The composition and formula of ruthenium sulfides were determined and the kinetic characteristics of the reduction of the compounds by hydrogen at high temperature were studied. On the basis of results obtained, it was suggested that the original noncrystalline compound of Ru_2S_3·10H_2O possessed the structure of RuS·RuS_2·10H_2O.
