摘要
采用硫代乙酰胺(CH_3CSNH_2)均相沉淀Ru(Ⅳ),人工合成了一种新的钌硫化合物。经扫描电镜(SEM)能谱分析,微库仑滴定分析,氢还原特性研究,DSC与DTG测定及红外光谱(IR)分析,测定该化合物的分子式为:RuS·RuS_2·10H_2O_oX-射线衍射鉴定为非晶态。将该化合物密封在真空石英管内,经520℃,40h热处理,产物热分解脱S并晶化为晶态Ru与晶态RuS_2。
A new noncrystalline ruthenium sulfide was synthesized by homogeneous phase precipitation Ru (Ⅳ) with thioacetamide (CH_3CSNH_2).The compound was investigated by SEM, micro-coulometric titration, IR, DSC, DTG, X-ray and hydrogen reduction.It is proved that the molecular formula of the compound is RuS·RuS_2·10H_2O· It is identified to be an amorphous compound by X-ray.Upon heating the amorphous compound at 520℃ for 40h in vacuum-tight tube, the crystallization of Ru and RuS_2 occurred.
