Special Issue Information

Dear Colleagues,

The oxidation processes in the field of catalysis take a major role in both industrial chemistry and environmental protection. Indeed, for the latter, the total oxidation reactions of volatile organic compounds (VOCs) and hydrocarbons is critical for pollution control in industrial processes and mobile sources. The presence of a mixture of organic and inorganic compounds (e.g., CO, VOC, NOx, SOx, among others) affects the difficulty to obtain stable, active, and selective catalytic materials. A second way to eliminate these pollutants corresponds to the selective oxidation of these to produce highly valuable chemical compounds such as fuel and alcohols. This methodology has also been used to produce chemical compounds from biomass. Moreover, the development of the photocatalytic or plasma catalysis techniques permits the intensification of low-energy processes.

This Special Issue of Catalysts aims at covering recent progress and novel trends in the field of catalytic oxidation reaction. Topics to be addressed in this special issue include the influence of different parameters on the catalytic activity at various scales (atomic, laboratory, pilot, or industrial scale), the development of new catalytic material of environmental or industrial importance, as well as the development of new methods, both microscopic and spectroscopic, to analyze oxidation processes.

Authors with expertise in these topics are cordially invited to submit their manuscripts to Catalysts. Significant full original papers and review articles are welcome.

Catalytic total oxidation is an effective technique for the treatment of industrial VOCs principally resulting from industrial processes using solvents, and usually containing mono-aromatics (BTEX) and oxygenated compounds (acetone, ethanol, butanone). The catalytic total oxidation of VOCs on noble metal materials is effective. However, the cost of catalysts is a main obstacle for the industrial application of these VOC removal processes. Therefore, the aim of this work is to propose an alternative material to palladium-based catalysts (which are suitable for VOCs’ total oxidation): a mixed oxide synthesized in the hydrotalcite way, namely CoAlCeO. This material was compared to four catalytic materials containing palladium, selected according to the literature: Pd/α-Al2O3, Pd/HY, Pd/CeO2 and Pd/γ­Al2O3. These materials have been studied for the total oxidation of toluene, butanone, and VOCs mixtures. Catalysts’ performances were compared, taking into account the oxidation byproducts emitted from the process. This work highlight that the CoAlCeO catalyst presents better efficiency than Pd-based materials for the total oxidation of a VOCs mixture. Full article

In this work, silica–titania supported catalysts were prepared by a sol–gel method with various compositions. Vanadia was impregnated on SiO2-TiO2 with different loadings, and materials were investigated in the partial oxidation of methanol and methyl mercaptan to formaldehyde. The materials were characterized by using N2 physisorption, X-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRF), X-ray photoelectron spectroscopy (XPS), Scanning transmission electron microscope (STEM), NH3-TPD, and Raman techniques. The activity results show the high importance of an optimized SiO2-TiO2 ratio to reach a high reactant conversion and formaldehyde yield. The characteristics of mixed oxides ensure a better dispersion of the active phase on the support and in this way increase the activity of the catalysts. The addition of vanadium pentoxide on the support lowered the optimal temperature of the reaction significantly. Increasing the vanadia loading from 1.5% to 2.5% did not result in higher formaldehyde concentration. Over the 1.5%V2O5/SiO2 + 30%TiO2 catalyst, the optimal selectivity was reached at 415 °C when the maximum formaldehyde concentration was ~1000 ppm. Full article
