AuNP@TiO₂Catalyzed Peroxidation of Ethyl- andn-Propylbenzene: Exploring the Interaction Between Radical Species and the Nanoparticle Surface

CeFe-Based Bead Nanocomposites as Catalysts for Oxidation of Ethylbenzene Reaction

“…This supports the idea that the reactivity of the binary nanocasted oxides under study is thanks to the transition metals Fe 3+ /Fe 2+ and Ce 4+ /Ce 3+ pairs having predominant Lewis acid sites, which is demonstrated by using transition metals and which act as catalysts for oxidation reactions [17,39,40]. The ethylbenzene oxidation reaction over the monoxides may follow similar approaches for mechanistic considerations as those of gold nanoparticles-catalyzed epoxidation of stilbene by involving a formation of a reactive oxygen species through the metal nanoparticles surface, which induces the decomposition of the peroxyl radical intermediate [41,42]. On the contrary, adding a third metal to the binary oxides further improves the reactivity of CFC, CFN, and CFM composites with CFN holding the best conversion among the ternary oxides studied.…”
