The X-ray diffraction (XRD) patterns showed C-type body-centered cubic phase, space group Ia-3, and the crystallite size values were found in the range of 19.45–32.34 nm depending on the ...

2021年5月1日 · Tetrabutylammonium hydroxide (TBAOH) was included in the sol–gel precursor to prepare the porous gadolinium titanates. The influences of the TBAOH template on the characteristics of the gadolinium titanates were investigated. The TBAOH played a key role for the porous structure in the samples.

2009年11月15日 · In this paper we present the results of the adsorption, from the vapor phase, of tert-butyl hydroperoxide (TBHP) over alumina and zirconia supported vanadia catalysts, which were found to be active for dibenzothiophene oxidation to the corresponding sulphone.

X-ray diffraction pattern (XRD), Thermogravimetric analysis (TGA), Fourier transforms infrared (FTIR), UV/visible, and photoluminescence spectroscopic techniques were employed to determine the...
