Síntese e caracterização de nanocatalisadores de platina suportados aplicados à reação de reforma do metano
(Universidade Federal de São Carlos, 2010-03-05)
Colloidal Nanoparticles of Platinum (Pt-NPs) were obtained by reducing hexacloroplatinic acid with ethylene glycol in the presence of polyvinylpyrrolidone (PVP) as protective agent of the particles. Two methods of synthesis ...
Formação de acetato de etila a partir do etanol sobre catalisadores de Cu/ZrO2: efeito da carga de cobre nas propriedades físicas e catalíticas
(Universidade Federal de São Carlos, 2010-03-10)
The ethanol dehydrocoupling in ethyl acetate distinguishes among the reactions of alcohol transformation in products with higher added value. Due to the possibility of obtaining ethanol from biomass in Brazil, the production ...
