Abstract

Kinetic study for the heterogeneous decomposition of hydrogen peroxide over different non-soluble metal oxides (CuO, Fe2O3 and PbO2) was taken as a model reaction, mainly in normal micellar, inverse micellar microemulsion of sodium dodecyl sulfate (SDS). Other micellar phases of different surfactants [sodium dioctylsulfosuccinate (AOT), cetyle trimethyl ammonium bromide (CTAB) and triton X100] have been studied. Different organic solvents have been investigated. A promotional effect was generally observed. The reaction rate determining step was estimated. Reaction rate constants and thermodynamic parameters (ΔG*, ΔH* and ΔS*) were calculated. It was found that the highest promotional influence was observed in the case of (SDS/Fe3O4) in micellar and inverse micellar micro-emulsion media.

Kurzfassung

Die Untersuchung der Kinetik des heterogenen Zerfalls von Wasserstoffperoxid über verschiedene nichtlösliche Metalloxide (CuO, Fe2O3 and PbO2) wurde hauptsächlich in normalen mizellaren und inversmizellaren Mikroemulsionen von Natriumdodecylsulfat (SDS) als Modellreaktion genommen. Andere mizellaren Phasen von verschiedenen Tensiden [Natriumdioctylsulfosuccinat (AOT), Cetyl-trimethylammoniumbromid (CTAB) und Triton X100] sind in verschiedenen organischen Lösungsmitteln untersucht worden. Allgemein wurde ein fördernder Effekt beobachtet. Die Geschwindigkeit des reaktionsbestimmenden Schrittes wurde abgeschätzt und die Reaktionsgeschwindigkeitskonstante sowie die thermodynamischen Parameter (ΔG*, ΔH* and ΔS*) berechnet. Der höchste fördernde Einfluss wurde im Fall von (SDS/Fe3O4) in mizellarem und inversmizellarem Mikroemulsionsmedium gefunden.
