Mesoporous structure, surface acidity and catalytic properties of Pt/Zr–MCM-41 catalysts promoted with 12-tungstophosphoric acid
Jin An Wang,Lifang Chen,L.E. Noreña,Juan Navarrete,M. E. Llanos,J. L. Contreras,Octavio Novaro +6 more
TL;DR: The influence of the Si/Zr molar ratio on the crystalline structure, textural properties, morphological features and surface acidity of Zr-MCM-41 mesoporous molecular sieves was investigated by X-ray diffraction (XRD), N 2 adsorption-desorption isotherms, 29 Si MAS NMR, TEM and FTIR spectroscopy of pyridine adhesorption techniques as mentioned in this paper.
Journal ArticleDOI
Surface chemistry and catalytic properties of VOX/Ti-MCM-41 catalysts for dibenzothiophene oxidation in a biphasic system
Julio González,Lifang Chen,Jin An Wang,Ma. Manríquez,R. Limas,P. Schachat,Juan Navarrete,J. L. Contreras +7 more
TL;DR: In this paper, a series of vanadium oxide supported on Ti-MCM-41 catalysts was synthesized via the incipient impregnation method by varying the vanadia loading from 5 to 10, 15, 20 and 25 wt%.

Synthesis of Nanoporous TiO2 Thin Films for Photocatalytic Degradation of Methylene Blue
M. Estrada,C. Reza,J. Salmones,Jin An Wang,M. E. Manríquez,J. M. Mora,M. L. Hernández,A. Zúñiga,J. L. Contreras +8 more
TL;DR: In this paper, a structure and photocatalytic activity of nanoporous titania (TiO2) thin films by an anodizing approach was reported, which showed that tetragonal anatase was the main phase in thin films that consisted of countless disordered nanopores in the order of 10 to 15 nm.
