Description of redox reactions is critically important for understanding and rational design of materials for electrochemical technologies, including metal-ion batteries, catalytic surfaces, or redox-flow cells. Most of these technologies utilize redox-active transition metal compounds due to their rich chemistry and their beneficial physical and chemical properties for these types of applications. A century since its introduction, the concept of formal oxidation states (FOS) is still widely used for rationalization of the mechanisms of redox reactions, but there exists a well-documented discrepancy between FOS and the electron density-derived charge states of transition metal ions in their bulk and molecular compounds. We summarize our findings and those of others which suggest that density-driven descriptors are, in certain cases, better suited to characterize the mechanism of redox reactions, especially when anion redox is involved, which is the blind spot of the FOS ansatz.

AbstractA review is given of the application of ESR spectroscopy to the study of hydrated transition metal ions and nitroxide spin probes in the interlamellar region of smectites and vermiculites. These investigations have not only provided information regarding the structure and mobility of the intracrystalline water-cation layers but have also demonstrated the reactivity and catalytic properties of certain transition metal exchange forms of smectites. Several novel coordination complexes and redox reactions between the exchange ions and a variety of simple organic molecules have been characterized.

Catalysed Oxidation

Many kinetic and mechanistic studies are reported on the direct and transition metal ion catalysed oxidation of tellurium(IV) with oxidants like persulphate, periodate, chromium(VI), hexacyanoferrate(III), cerium(IV), manganese(III), cobalt(III) etc. Similar studies on the reduction of tellurium(VI) by different reductants are much fewer. An attempt has been made to discuss in brief up-to-date information available on the nature of tellurium(IV) and tellurium(VI) species as well as kinetic and mechanistic studies on the direct and catalysed oxidation and reduction reactions of tellurium(IV) and tellurium(VI) respectively. The majority of reactions concerned with the oxidation of tellurium(IV) to tellurium(VI) seems to prefer a complementary path to a non-complementary one, in accordance with Schaffer's principle of equivalent change.
