Publikováno v: Catalysts, Vol 13, Iss 3, p 548 (2023)
The pyrolysis of the biomass Agave salmiana bagasse (10 K/min, ambient to 700 °C) was investigated in the absence and presence of Aerosil and MCM-41 catalysts. MCM-41 was synthetized using a typical hydrothermal method and characterized with XRD, SA

Structure, Acidity, and Redox Aspects of VOx/ZrO2/SiO2 Catalysts for the n-Butane Oxidative Dehydrogenation
Autor: José-Luis Sánchez-García, Brent E. Handy, Ilse N. Ávila-Hernández, Angel G. Rodríguez, Ricardo García-Alamilla, Maria-Guadalupe Cardenas-Galindo
Publikováno v: Catalysts, Vol 10, Iss 5, p 550 (2020)
ZrOx/SiO2 and VOx/ZrOx/SiO2 catalysts (5 wt %–25 wt % Zr, 4 wt % V) were prepared by grafting zirconium and vanadium alkoxides on Aerosil 380. All samples were characterized by temperature programmed reduction, N2 physisorption, X-ray diffraction,

Lewis–Br⊘nsted induction acidity in SBA-15 modified with Zr and P
Autor: Juan Reyes-Gómez, Ricardo García-Alamilla, Francisco Paraguay-Delgado, Karina Cruz-Rodríguez, Brent E. Handy, María-Guadalupe Cárdenas-Galindo
Publikováno v: International Journal of Materials Research. 109:957-963
In this work, we present the synthesis of SBA-15 materials modified with 6 and 9 mol.% of Zr and P, respectively. Silanol SBA-15 groups were detected by Fourier transform infrared spectroscopy. X-ray diffractograms revealed that the typical hexagonal
