The chemical potential of a component of a binary metastable compound is considered in the single-phase and in the compositionally non-variant two-phase regime. A detailed thermodynamic analysis reveals striking differences for identical nominal compositions. Without the loss of generality the

The reaction path of the Cl(2) evolution reaction (CER) was investigated by combining electrochemical and spectroscopic methods. It is shown that oxidation and reconstruction of the catalyst surface during CER is a consequence of the interaction between RuO(2) and water.

Sodium, niobium, and tantalum phosphate bronzes Na(4)M(8)P(4)O(32) (M=Nb, Ta) are employed as photocatalysts for water splitting to reveal the effects of the distortion of metal-oxygen octahedra on the photocatalytic performance. Addition of RuO(2) as a co-catalyst leads to high, stable

Ruthenium oxides (RuO(2)·1·10H(2)O and RuO(2)) have been synthesized by forced hydrolysis and oxidation of ruthenium chloride. The resulting materials were extensively characterized to determine the crystallinity, surface area, and ruthenium oxidation state. Surface charging experiments indicate a large quantity of
