Effects of solvent and structure on the reactivity of 6-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents / Uticaj rastvarača i strukture na reaktivnost 6-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2009)
The rate constants for the reactions of diazodiphenylmethane (DDM) with 6-substituted nicotinic acids in aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents, together with ...
Synthesis, characterization and electrocatalytic activity for ethanol oxidation of carbon supported Pt, Pt-Rh, Pt-SnO2 and Pt-Rh-SnO2 nanoclusters
(Elsevier Science Inc, New York, 2009)
Nanoclusters of Pt, Pt-Rh, Pt-SnO2 and Pt-Rh-SnO2 were successfully synthesized by polyol method and deposited on high-area carbon. HIRTEM and XRD analysis revealed two phases in the ternary Pt-Rh-SnO2/C catalyst: solid ...
