Bentonite buffers at temperatures beyond 100 °C could reduce the amount of high-level radioactive waste in a deep geological repository. However, it is necessary to demonstrate that buffer surrounding canisters withstands such elevated temperatures, while maintaining its safety functions (regarding long-term performance). For this reason, an experiment with thermal loading bentonite powder 150 was arranged. The paper presents changes Czech Mg/Ca underwent during heating for one year. These...
Laboratory synthesis of microsheets titanium dioxide from titanyl sulfate involves the use ammonia solution, whereas another inorganic base is most likely to be employed at industrial level, as a toxic agent and therefore should avoided according European Union (EU) regulations. Selected nontoxic bases such sodium, potassium, lithium hydroxides have been tested an alternative solution obtain amorphous crystalline TiO2-based microsheets. The final products obtained each step procedure...
The aim of this study was to explore the influence various n-propylamines (mono, di, and tri) tert-butylamine on properties prepared peroxo-titanates annealed TiO2. Detailed structural characterization (SEM, TEM with EDX, XRD) confirmed 2D-foil morphology TiO2 nanocrystals CHNS analysis together XPS showed presence carbon (under 1 wt%). excellent photocatalytic activity up four times higher decomposition rate constant upon UV irradiation than P25. Favourable growth crystals observed...
Organic compounds bound to peroxotitanates can influence the photocatalytic activity of TiO2 nanoparticles (NPs) obtained by annealing. Knowledge on how this plays out is fundamental for development NPs with desirable catalytic behavior, which be used several applications. Thermoanalytical techniques simulate annealing process a small scale, but there lack literature topic. This especially true nitrogen-containing organic compounds, are not often as modifiers. Here, we present study...
