Preparation of In,H-ZSM-5 for DeNOx reactions by solid-state ion exchange

Autor: Á. Szegedi, R.M. Mihályi, Z. Schay

Publikováno v: Catalysis Today. 143:253-260

A simple method is proposed to prepare In,H-ZSM-5 catalyst for DeNOx reactions. This consists of mechanically mixing the fine powders of In2O3 and H-ZSM-5 followed by heating in oxygen free inert gas flow to 580 °C where indium undergoes thermal aut

Autor: Janos Kokavecz, Z. Schay, G. Kurdi, Zsolt Bor, Karoly Osvay, Othmar Marti, V. Megyesi, Mária Csete

Publikováno v: Materials Science and Engineering: C. 26:1056-1062

Sub-micrometer periodic structures were prepared on the surface of poly-carbonate films by UV laser treatment methods: a) grating-like structures having a period of 156 nm were induced by ArF excimer laser, b) 416 nm and 833 nm periodic gratings were

Structure and catalytic activity of copper, nickel, and platinum graphimets prepared from graphite intercalation compounds

Autor: Mihály Bartók, László Guczi, Ágnes Mastalir, Z. Schay, Árpád Molnár, G. Sirokmán

Publikováno v: Carbon. 28:35-42

Commercially available copper, nickel, and platinum graphimets prepared from intercalated graphite materials were investigated by XPS, TEM, XRD, DSC and chemisorption techniques. The catalytic activity was tested in hydrogenation reactions. The XPS,

Vanadium oxide supported on gallium and indium oxides: Synthesis, physicochemical and catalytic properties

Autor: V. Cortés Corberán, B. Sulikowski, Anna Kubacka, Z. Schay, E. Wioch, R.X. Valenzuela

Vanadium oxide was supported on gallium(III) and indium(III) oxides, with the vanadium superficial coverage from 0.6 to 1.8 of the theoretical monolayer. A stronger vanadia/support interaction was observed by Raman and XPS spectroscopies for the V-Ga
