XAS studies of Sn modified TiO[sub]2 coatings
Ksenija Maver, Iztok Arčon, Urška Lavrenčič Štangar
Objavljeni povzetek znanstvenega prispevka na konferenci
Oznake: kositer;EXAFS;TiO2 fotokatalizator;
Coatings based on TiO2 are extensively investigated material for the preparation of surfaces which are referred as self-cleaning. Under solar illumination these coatings catalyze pollutants degradation and enhance their removal from the surface due to photoinduced superhydrophilicity [1]. There are ...

Improved photocatalytic activity of anatase-rutile nanocomposites induced by low-temperature sol-gel Sn-modification of TiO [sub] 2
Ksenija Maver, Iztok Arčon, Mattia Fanetti, Saim Emin, Matjaž Valant, Urška Lavrenčič Štangar
Izvirni znanstveni članek
Oznake: Anatase-rutile;Sn-modified TiO2;XAS analysis;photocatalytic activity;
The Sn-modified TiO2 photocatalysts are prepared by low-temperature sol-gel processing based on organic titanium and tin precursors with varied Sn concentrations (from 0.1–20 mol .%). The role of Sn dopant as the promotor of the formation of TiO2 rutile crystalline phase is explained and the optim ...

Due to many advantageous physiochemical properties, titanium dioxide (TiO2) is the most widely used photocatalyst in numerous applications, such as wastewater treatment and air purification, self-cleaning surfaces and energy conversion (H2 generation). However, one of its disadvantages is the high e ...

The objective of this research was to investigate how the photocatalytic activity of pure TiO2 can be improved by SnO2 modification. Different molar ratios of tin to titanium were prepared. The correlation between tin concentration and structural properties was investigated to explain the mechanis ...

Nickel-decorated ZnO nanoparticles for effective solar reduction of hexavalent chromium and removal of selected pharmaceuticals
Miha Ravbar, Ksenija Maver, Tilen Knaflič, Iztok Arčon, Nataša Novak Tušar, Urška Lavrenčič Štangar, Andraž Šuligoj
Izvirni znanstveni članek
Oznake: nanodelci;nikel;krom;
The efficient visible light driven photocatalytic reduction of hexavalent chromium, Cr(VI) was demonstrated using ZnO nanoparticles (NPs) decorated with oxo-clusters of transition metals. The ZnO NPs were synthesized by a facile one-pot solvothermal synthesis followed by a fast microwave-assisted (M ...
