Journal ArticleDOI
Iron oxide modified mesoporous carbons: Physicochemical and catalytic study
Christo Minchev,Holger Huwe,Tanya Tsoncheva,Daniela Paneva,Momtchil Dimitrov,Ivan Mitov,Michael Fröba +6 more
TL;DR: In this paper, the state and reductive phase transformations of the loaded iron oxide particles were investigated using TPR, XAFS, Moessbauer spectroscopy and methanol decomposition as a catalytic test.
Journal ArticleDOI

TL;DR: In this article, a complex of various physicochemical methods, such as low temperature physisorption of nitrogen, XRD, EPR, XPS, UV-Vis and TPR with hydrogen, were applied for qualitative and quantitative determination of oxygen-containing groups on the carbon surface before and after cobalt deposition.
Journal ArticleDOI
Nanostructured copper-zirconia composites as catalysts for methanol decomposition
Tanya Tsoncheva,Izabela Genova,Momchil Dimitrov,Eva Sarcadi-Priboczki,Anna Maria Venezia,Daniela Kovacheva,Nicola Scotti,Vladimiro Dal Santo +7 more
TL;DR: In this article, a mesoporous ZrO2 was obtained by hydrothermal synthesis using surfactant assisted approach and the obtained materials were characterized by N2 physisorption, XRD, UV-vis, FTIR, XPS and temperature programmed reduction with hydrogen and tested as catalysts in methanol decomposition to hydrogen and CO.
Journal ArticleDOI
Iron and copper oxide modified SBA-15 materials as catalysts in methanol decomposition: Effect of copolymer template removal
TL;DR: In this paper, several SBA-15 type mesoporous silicas, where different means of surfactant removal have been used, have been modified by copper and iron oxide, and tested as catalyst for methanol decomposition.
Journal ArticleDOI
Novel preparation of nanosized mesoporous SnO2 powders: Physicochemical and catalytic properties
TL;DR: In this article, two series of catalytically active SnO2 powders were prepared from tin(IV) tert-butoxide and tin (IV) chloride as tin precursors.
