Journal ArticleDOI
Azo-dye orange II degradation by the heterogeneous Fenton-like process using a zeolite Y-Fe catalyst—Kinetics with a model based on the Fermi's equation
TL;DR: In this article, the degradation of Orange II dye (OII) by a heterogeneous Fenton-like process was studied using a catalyst with 5.1% of iron after ion exchange in a Na-Y zeolite support.
Journal ArticleDOI
The influence of Pd–Ag catalyst restructuring on the activation energy for ethylene hydrogenation in ethylene–acetylene mixtures
Hugo Zea,Kelvin Lester,Abhaya K. Datye,Ed G. Rightor,Robert J. Gulotty,Wendy Waterman,Michael G. Smith +6 more
TL;DR: In this article, the presence of co-adsorbed CO and changes in the surface structure of Pd-Ag surfaces together with high temperature reduction have been shown to alter the reaction behavior of an industrially significant selective hydrogenation reaction.
Journal ArticleDOI
Empirical kinetics for the growth of titania nanotube arrays by potentiostatic anodization in ethylene glycol
TL;DR: In this article, the effects of the main anodization variables on the morphology of the resulting titania nanotube arrays were investigated. Butts et al. described the effects on the tube morphology using a simple, empirical kinetic expression.
Journal ArticleDOI
Reductive/expansion synthesis of zero valent submicron and nanometal particles
TL;DR: In the case of urea/nitrate mixtures, there is a convolution of decomposition processes, leading to the formation of metal rather than oxide, resulting in highly dispersed particles.
Journal ArticleDOI
Synthesis of WS2 nanostructures from the reaction of WO3 with CS2 and mechanical characterization of WS2 nanotube composites.
TL;DR: Nanoindentation and nano-impulse techniques were used to characterize the mechanical properties of polymer matrix-WS(2) nanotube composites, finding them superior to equivalent SWCNT composites.
