Tehnologija veriženja blokov
MATEJ ARČON, Tomaž Dobravec
Diplomsko delo
Oznake: veriženje blokov;kriptovalute;omrežje Bitcoin;
Tehnologija veriženja blokov je danes ena najodmevnejših novosti v svetu računalništva. Čeprav so izdelki, ki uporabljajo to tehnologijo, še v zgodnjih fazah razvoja, se zdi, da imajo velike možnosti za izboljšanje življenja ljudi na različnih področjih. Širši javnosti je najbolj znana uporaba veriž ...

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 ...

ǂThe ǂrole of lattice defects on the optical properties of TiO[sub]2 nanotube arrays for synergistic water splitting
Manel Machreki, Takwa Chouki, Georgi Tyuliev, Mattia Fanetti, Matjaž Valant, Denis Arčon, Matej Pregelj, Saim Emin

Oznake: defects;lattices;oxides;photonics;redox reactions;
In this study, we report a facile one-step chemical method to synthesize reduced titanium dioxide (TiO$_2$) nanotube arrays (NTAs) with point defects. Treatment with NaBH$_4$ introduces oxygen vacancies (OVs) in the TiO$_2$ lattice. Chemical analysis and optical studies indicate that the OV density ...

Structural and chemical analysis of hard carbon negative electrode for Na-ion battery with X-ray Raman scattering and solid-state NMR spectroscopy
Ava Rajh, Matej Gabrijelčič, Blaž Tratnik, Klemen Bučar, Iztok Arčon, Marko Petric, Robert Dominko, Alen Vižintin, Matjaž Kavčič
Izvirni znanstveni članek
Oznake: trdi ogljik;hard carbon;
This study explores the structural changes of hard carbon (HC) negative electrodes in sodium-ion batteries induced by insertion of Na ions during sodiation. X-ray Raman spectroscopy (XRS) was used to record both C and Na K-edge absorption spectra from bulk HC anodes carbonized at different temperatu ...

Light-assisted catalysis and the dynamic nature of surface species in the reverse water gas shift reaction over Cu/[gamma]-Al[sub]2O[sub]3

The reverse water gas shift (RWGS) reaction converts CO2 and H2 into CO and water. We investigated Cu/γ-Al2O3 catalysts in both thermally driven and light-assisted RWGS reactions using visible light. When driven by combined visible light and thermal energy, the CO2 conversion rates were lower than i ...
