Abstract

The solid-phase reaction of [Pt(NH₃)₄]Cl₂ and (NH₄)₆Mo₇O₂₄ under argon in the temperature range from 50 to 500°C was studied by thermal analysis and mass spectrometry. According to the X-ray powder diffraction, X-ray photoelectron spectroscopy, and elemental analysis data, the product consists of ordered Pt₃Mo phase with an insignificant amount of molybdenum(VI) oxide. The described reaction is accompanied by reduction of the metals, which is promoted by Pt²⁺ ions in the presence of ammonia.

摘要

通过热分析和质谱研究了[Pt（NH ₃）₄ ] Cl ₂和（NH ₄）₆ Mo ₇ O ₂₄在氩气下于50至500℃的固相反应。根据X射线粉末衍射，X射线光电子能谱和元素分析数据，该产物由有序的Pt ₃ Mo相和少量的氧化钼（VI）组成。所述反应伴随着金属的还原，在氨存在下，Pt ²⁺离子促进了金属的还原。
