Synthesis and Characterization of MCM-41 Nanomaterials Containing Titanium and Application for Catalytic Oxidation of BTEX

Received: 17 August 2022;  Published: 30 May 2023;  doi: 10.21926/cr.2302017


The TiO2/MCM-41 nanomaterials were synthesized by impregnation with an excess solvent with different percentages of titanium dioxide. They were used for catalytic degradation of Benzene Toluene Ethylbenzene and Xylenes (BTEX) in the presence of hydrogen peroxide in aqueous media. The obtained materials were characterized by X-ray Diffraction, nitrogen adsorption-desorption using the BET method and Fourier Transform Infrared Spectroscopy. The nanostructured phase of the hex [...]

Obtaining TiO2 Nanostructures by Electrospinning and Analysis of Absorbance in the UVA Spectrum for Photocatalytic Application

Received: 14 December 2022;  Published: 17 April 2023;  doi: 10.21926/cr.2302016


The synthesis of fibers by electrospinning allows for obtaining nanostructures of one-dimensional materials with good flexibility, optical and catalytic properties, high surface area and porosity. They can be used in applications such as: catalysts, solar cells, fuel cells, membranes, and hydrogen batteries, among others. Here we emphasize that few reports in the literature describe the existing synergism between the optical and photocatalytic properties of TiO2, and the i [...]

Organic Structure-Directing Agent Free Synthesis of Mordenite with Seeds, Used as A Support for Mo Catalysts in the Transesterification of Soybean Oil

Received: 20 December 2022;  Published: 07 April 2023;  doi: 10.21926/cr.2302015


This work prepared mordenite using seeds and without organic structure-directing agents (OSDAs). The Mo/Mordenite was prepared through wet impregnation and the catalysts’ performance was checked for transesterification of soybean oil with methanol. The mordenite zeolite was prepared through hydrothermal crystallization under static conditions with a molar composition of 6Na2O:Al2O3:30SiO2:780H2 [...]
