Catalyst, Co-ion and the Media Effect on the Oscillatory Behavior of Resorcinol in the BZ Reaction
نویسنده
چکیده
O estudo diz respeito ao comportamento oscilatório de resorcinol como substrato orgânico na reação de Belousov-Zhabotinsky (BZ) em presença de diferentes íons metálicos como catalisadores no meio aquoso ácido. Verifica-se que íons Mn como catalisador são mais reativos que íons Fe. Variando o meio aquoso ácido observa-se que as espécies protonadas são mais facilmente formadas em ácido sulfúrico do que o substrato orgânico (resorcinol) e devido a isto um número maior de oscilações é observado neste meio. Além disso, foi estudado o efeito de diferentes ânions como acetato, carbonato e sulfato, associados com o mesmo íon metálico (Mn) como catalisador, sobre o comportamento oscilatório do sistema. Um modo misto das oscilações é observado mudando a concentração de ácido sulfúrico.

Ethanol electrooxidation on the Co@Pt core-shell nanoparticles modified carbon-ceramic electrode in acidic and alkaline media
In this study, the electrocatalytic activity of the Co@Pt core-shell nanoparticles toward the ethanol oxidation reaction has been investigated by cyclic voltammetry and chronoamperometry in acidic and alkaline media in details. The physicochemical data obtained in alkaline solution are compared to those in acidic solution. The obtained results demonstrate that while in the both media Co@Pt core...
متن کاملControlling chemical oscillations in heterogeneous Belousov-Zhabotinsky gels via mechanical strain.
We performed theoretical and computational studies to determine the effect of an applied mechanical strain on the dynamic behavior of heterogeneous polymer gels undergoing the oscillatory Belousov-Zhabotinsky (BZ) reaction. In these spatially heterogeneous gels, the catalyst for the reaction is localized in specific patches within the polymer network and the BZ reaction only occurs within these...

In this research we used Heavy Propylene Tetramer (HPT) and A1C13 —BF3 (Lewis acids) ascatalyst and ethanol, n-propanol and n-butanol as co-catalyst. Using Lewis acids as catalyst, theHPTs form molecules with higher molecular weight. Since the raw materials of the reaction are byproducts of other reactions, are not pure and contain various compounds with different M.W andalso different chemical...

The phenomenon of capillary condensation is studied through the weight change of condensed phase in an internally wetted porous pd catalyst pellet during the course of exothermic reacation of cyclohexane hydrogenation in a thermogravimetric analyzer (TGA). The direct measurement of condensed phase indicates that evaporation of condensed phase is confined to the macropores of catalyst pellet at ...
