Razvoj katalizatorjev za magnetno segrevano oksidacijo propena v propilen oksid z molekularnim kisikom
Katja Svetek, Sašo Gyergyek, Janvit Teržan
Magistrsko delo
Oznake: magnetni nanodelci;magnetno segrevanje;selektivna oksidacija;propilen oksid;magistrske naloge;
Propilen oksid je komercialna kemikalija z velikim industrijskim pomenom. Metode za pridobivanje propilen oksida imajo dve glavni pomanjkljivosti – onesnaževanje okolja in visoke stroške proizvodnje. Začeli so razvijati nove metode, med drugim tehnologije pridobivanja propilen oksida z neposredno ep ...

Effect of Na, Cs and Ca on propylene epoxidation selectivity over CuO[sub]x/SiO[sub]2 catalysts studied by catalytic tests, in-situ XAS and DFT
Janvit Teržan, Matej Huš, Iztok Arčon, Blaž Likozar, Petar Djinović
Izvirni znanstveni članek
Oznake: alkali modification;propylene epoxidation;reaction mechanism;copper oxide;activation barrier;
This research focuses on epoxidation of propylene over pristine, Na, Ca and Cs modified CuOx/SiO2 catalysts using O2. The selectivity of the reaction is analyzed using a combination of catalytic tests, in-situ XAS and DFT calculations. The initially present subnanometer CuO clusters are present i ...

Dry reforming of methane (DRM) is a promising way to convert methane and carbon dioxide into H2 and CO (syngas). CeO2 nanorods, nanocubes, and nanospheres were decorated with 1−4 wt % Ni. The materials were structurally characterized using TEM and in situ XANES/EXAFS. The CO2 activation was anal ...
