Synthetic Route of 10049-08-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 10049-08-8, Name is Ruthenium(III) chloride. In a document type is Article, introducing its new discovery.
A series of novel ruthenium-manganese oxide (denoted as RunMn1-nOx) has been formed by oxidative co-precipitating. The precursor was obtained by mixing Mn(VII) (potassium permanganate), Mn(II) (manganese acetate) and Ru(III) (ruthenium chloride) in neutral aqueous solution at room temperature. The powder of RunMn1-nOx was obtained by calcinating the precursor at appropriate temperature. The crystalline structure and electrochemical performance of the powder have been studied as a function of the calcination temperature. At appropriate calcination temperature (e.g. 170 C), the powder is in hydrous amorphous phase with a high specific capacitance. When the calcination temperature reaches up to 350 C, the crystal form of alpha-MnO2 is formed, but the ruthenium oxide still keeps amorphous structure, which will lead to the decrease of specific capacitance of the composite electrode materials. The X-ray photoelectron spectroscopy (XPS) analysis shows that the powder of RunMn1-nOx prepared in this study belongs to the composite of RuO2-MnO2. The results from cyclic voltammetry (CV), chronopotentiometry and electrochemical impedance spectroscopy (EIS) indicate that the ruthenium weight density of 9 wt% in RunMn1-nOx can improve the cost-performance of ruthenium-manganese composite electrode.
