Enhancement of ethanol oxidation on Pd nanoparticles supported on carbon-antimony tin oxide hybrids unveils the relevance of electronic effects
(2017-01-01)
A comparative study of activity toward ethanol oxidation was carried out for catalysts having the same loading of identical Pd nanoparticles supported on carbon-oxide hybrids containing antimony tin oxide (Sb2O5/SnO2– ATO) ...
Quantitative determination of the number of active surface sites and the turnover frequencies for methanol oxidation over metal oxide catalysts: I. Fundamentals of the methanol chemisorption technique and application to monolayer supported molybdenum oxide catalysts
(Elsevier Science, 2000-11)
A detailed study of the methanol chemisorption and oxidation processes on oxide surfaces allowed the development of a method to quantify the number of surface active sites (Ns) of metal oxide catalysts. In situ infrared ...
Quantitative determination of the number of surface active sites and the turnover frequency for methanol oxidation over bulk metal vanadates
(Elsevier Science, 2003-02)
The present work investigates the number and nature of the surface active sites, selectivity and turnover frequency towards methanol selective oxidation of a series of bulk metal vanadates. The catalysts were synthesized ...
Quantification of active sites for the determination of methanol oxidation turn-over frequencies using methanol chemisorption and in situ infrared techniques. 1: Supported metal oxide catalysts
(American Chemical Society, 2001-10)
Methanol oxidation over metal oxide catalysts is industrially important for the production of formaldehyde, but knowledge about the intrinsic catalysis taking place is often obscured by a lack of knowledge as to the number ...
Theoretical study on the reactivity of the surface of pure oxides: The Influence of the support and oxygen vacancies
(Elsevier, 2013-06-01)
The surface reactivity of three oxides widely used as heterogeneous catalysts, CeO2 (ceria), Ga2O3 (gallia), and ZnO, with CO, CO2, and H2 was investigated. The most stable perfect (dehydroxylated) oxide surfaces, surfaces ...
Carbamazepine oxidation catalyzed by iron and manganese porphyrins supported on aminofunctionalized matrices
(ELSEVIER SCIENCE BV, 2008)
This work describes the catalytic activity of manganese and iron porphyrins, Mn and Fe(TFPP)Cl, covalently immobilized on the aminofunctionalized supports montmorillonite K-10 (MontX) and silica (SilX), where X= 1 or 2 ...
A comparative investigation of metal-support interactions on the catalytic activity of Pt nanoparticles for ethanol oxidation in alkaline medium
(2016-04-15)
The effects of interactions of Pt nanoparticles with hybrid supports on reactivity towards ethanol oxidation in alkaline solution are investigated. Studies involve catalysts with identical Pt nanoparticles on six hybrid ...
