Special Issue Information

Dear Colleagues,

The use of heterogeneous catalysts has been an inseparable part of any chemical industry and has always undergone changes for obtaining a better reaction performance. These changes are linked to catalyst design, synthesis, and modifications with the optimum goal to elevate the yield and selectivity towards the desired products. Similarly, environmental remediation of different pollutants using catalysts has been another area of research that has received an enormous amount of interest. In general, there are two key factors required for a catalyst to be assumed as a potential candidate in real industrial application—having a high activity/selectivity and being easily regenerated and reused. However, the availability and the cost of resources for developing those catalysts are an additional factor to be considered. The utilization of materials known as “catalyst supports” integrated with the catalyst has been a beneficial approach in catalyst development towards the lowering of the cost and elevating catalyst efficiency. The catalyst support is usually a material present in major amount in the supported catalyst and is stated to provide low or negligible catalytic activity, high surface area, thermal and mechanical stability, resistance to reaction medium, while it is also low-cost. The utilization of active catalysts supported inside continuous flow/microflow reactors is another prosperous modern strategy of great industrial interest, since the efficiency per mass of catalyst can reach enormous values. Finally, the catalyst-on-support approach can lead to single atom catalysts towards specific and selective catalytic reactions.

This Special Issue aims to collect research works highlighting the use of “material supports” in various important reactions involved in heterogeneous catalysis. Detailed study of the synthesis and modification of catalyst supports, the mechanism involved in support–catalyst interaction, and the advantages of using supported catalysts over unmodified catalysts are some of the key aspects which this issue shall focus on. Additionally, it shall present green-oriented approaches for the synthesis of supports, such as biopolymer and biomass-derived carbonaceous substrates. Finally, a highlight of the issue will be to compile works involving the use of material supports in various modes of catalysis such as thermocatalysis, electrocatalysis, sonocatalysis, photocatalysis, biocatalysis, etc. In this context, we invite the submission of original research papers, communications, and review articles presenting recent developments and trends in the synthesis, characterization, and applications of materials as catalyst support, with a preferable focus on chemical, biofuel synthesis. and environment-oriented applications, such as water/air remediation and biomass valorization.

The use of renewable local raw materials to produce fuels is an important step toward optimal environmentally friendly energy consumption. In addition, the use of these sources together with fossil fuels paves the way to an easier transition from fossil to renewable fuels. The use of simple organic acids as hydrogen donors is another alternative way to produce fuel. The present work reports the use of oxalic acid as a hydrogen donor for the catalytic hydrodesulfurization of atmospheric gas oil and the deoxygenation of rapeseed oil at 350 °C. For this process, one commercial NiW/SiO2–Al2O3 solid and two NiW/modified phonolite catalysts were used, namely Ni (5%) W (10%)/phonolite treated with HCl, and Ni (5%) W (10%)/phonolite treated with oxalic acid. The fresh phonolite catalysts were characterized by Hg porosimetry and N2 physisorption, ammonia temperature programmed desorption (NH3-TPD), X-ray diffraction (XRD), and X-ray fluorescence (XRF). The sulfided metal phonolite catalysts were characterized by XRD and XRF. Hydrodesulfurization led to a decrease in sulfur content from 1 to 0.5 wt% for the phonolite catalysts and to 0.8 wt% when the commercial catalyst was used. Deoxygenation led to the production of 15 and 65 wt% paraffin for phonolite and commercial solids, respectively. The results demonstrate the potential of using oxalic acid as a hydrogen donor in hydrotreating reactions. Full article
