TL;DR: In this article, the effect of CdO on the thermal decomposition of cobaltous carbonate was studied using thermogravity and electrical conductivity, and the results showed that the Co2+ ions are the active centres.

TL;DR: In this article, the effect of catalyst properties such as surface area, non-stoichiometry and electrical characteristics on the thermal decomposition of KClO4 was investigated using thermogravimetric analysis.

TL;DR: In this paper, the catalysed decomposition of KMnO4 in air was monitored using thermogravimetric analysis and electrical conductivity measurements, and it was found that such mixing greatly affects the decomposition path by promoting the formation of the intermediate unstable MnO4. radical through the presence of defect electrons produced in the V2O5 lattice.

TL;DR: In this article, texture studies of V2O5 doped with Fe3+, Co3+ and Ni2+ ions in the temperature range 110-600 °C were made by using N2 adsorption measurements.
