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 ...
Dependence of divalent metal ions on phosphotransferase activity of osseous plate alkaline phosphatase
(Elsevier B.V., 1997-04-01)
Kinetic evidence for the role of divalent metal ions in the phosphotransferase activity of polidocanol-solubilized alkaline phosphatase from osseous plate is reported. Ethylenediamine tetreacetate, 1,10-phenanthrolin, and ...
Synthesis, characterization, and thermal study of solid-state alkaline earth metal mandelates, except beryllium and radium
(Springer, 2014-07-01)
Characterization, thermal stability, and thermal decomposition of alkaline earth metal mandelates, M(C6H5CH(OH)CO2)(2), (M = Mg(II), Ca(II), Sr(II), and Ba(II)), were investigated employing simultaneous thermogravimetry ...
Chemical modification of the surface of alumina with alkaline earth metal oxides using the polymeric precursor method for catalysis application
(Associação Brasileira de Cerâmica, 2014-03-01)
In this study, modifications of alumina surface with of alkaline earth metal oxides were studied, using the polymeric precursor method. The modified compounds were characterized by X-ray diffraction, nitrogen adsorption-desorption ...
Mixed oxides tuned with alkaline metals to improve glycerolysis for sustainable biodiesel production
(Elsevier Science, 2017-01)
In this study, monoglycerides were produced as glycerol value-added products via transesterification reaction of methyl stearate. This green and selective process involved catalysis from hydrotalcite-like compounds with ...
Synthesis, characterization and catalytic evaluation of cobalt and niobium oxide solids modified with alkaline earth metals
(Universidade Federal do Rio de Janeiro, 2020-09)
Cobalt and niobium oxide solids modified with alkaline earth metals (Mg, Ca, and Sr) were synthesized and characterized to compare the second element effect on the catalyst structural and chemical properties. The materials ...
