Cobalt oxide species supported on SBA-15, KIT-5 and KIT-6 mesoporous silicas for ethyl acetate total oxidation
TL;DR: In this article, cobalt oxide modified SBA-15, KIT-5 and KIT 6 mesoporous silicas with different pore size/pore entrances have been synthesized by a conventional wet impregnation method using cobalt nitrate as the precursor.
Journal ArticleDOI
Mesoporous CeO2 : Synthesis by nanocasting, characterisation and catalytic properties
TL;DR: In this article, mesoporous CeO2 was synthesized by using CMK-3 carbon as a structure matrix, and the obtained products exhibit uniform pore walls with a diameter of ca. 5nm in a two-dimensional hexagonal periodic arrangement, as well as interparticle porosity.
Journal ArticleDOI
Mechanochemically synthesized nano-dimensional iron–cobalt spinel oxides as catalysts for methanol decomposition
TL;DR: In this article, phase composition and structural properties of iron-cobalt oxides are investigated by X-ray diffraction and Moessbauer spectroscopy, and their catalytic behavior in methanol decomposition to CO and methane is tested.
Journal ArticleDOI
Nanosized iron and iron–cobalt spinel oxides as catalysts for methanol decomposition
Elina Manova,Tanya Tsoncheva,Claude Estournès,Daniela Paneva,K. Tenchev,Ivan Mitov,L.A. Petrov +6 more
TL;DR: In this paper, X-rays diffraction, Mossbauer spectroscopy, magnetic measurements and temperature programmed reduction were used to study the catalytic behavior of mixed iron-cobalt oxides in methanol decomposition to H 2, CO and methane.
Journal ArticleDOI
Studies on the state of iron oxide nanoparticles in MCM-41 and MCM-48 silica materials
Ralf Köhn,Ralf Köhn,Daniela Paneva,Momtchil Dimitrov,Tanya Tsoncheva,Ivan Mitov,Christo Minchev,Michael Fröba +7 more
TL;DR: In this article, phase transformations in and catalytic properties of mesoporous MCM-41 and MCM 48 silica molecular sieves modified with iron oxide were studied by X-ray diffraction, nitrogen physisorption, Mossbauer spectroscopy, temperature-programmed reduction, and methanol decomposition as a catalytic test.
