Special Issue Information

Dear Colleagues,

One of the challenges of chemical synthesis, which deals with multistep synthetic routes to complicated molecules, is to improve the sustainability of the processes by simplifying separation and purification procedures. Although the usefulness of heterogeneous catalysis in this regard is undeniable, the development of new catalytic systems with improved efficiency is still necessary. Especially single heterogeneous catalysts with different functionalities or different compatible heterogeneous catalysts are of great interest in terms of carrying out one-pot or sequential tandem processes, without the need for purification of the intermediate products. These systems should make the whole process more cost-effective in terms of materials, time and energy consumption, and hence more sustainable in the context of a greener chemistry. These processes can be of special interest in fields such as the conversion of natural biomass into valuable chemicals or the synthesis of pharmaceuticals, where several reaction steps are usually needed.

This Special Issue will try to gather the most recent works dealing with the development and use of bifunctional heterogeneous catalysts or the application of two (or more) heterogeneous catalysts in one-pot or tandem reactions. It is our pleasure to invite you to contribute an original research paper or a review article for this Special Issue.

Facile Mechanochemical Synthesis of Nickel/Graphene Oxide Nanocomposites with Unique and Tunable Morphology: Applications in Heterogeneous Catalysis and Supercapacitors

In this study, a very simple and highly effective mechanochemical preparation method was developed for the preparation of Ni nanoparticles supported graphene oxide (GO) nanocomposites (Ni/GO, where Ni is a composition of Ni(OH)2, NiOOH, NiO, Ni2O3 and NiO2), 3 wt% NiO/GO (Ni/GO-1) and 8 wt% NiO/GO(Ni/GO-2). The developed method is not only very simple and efficient, but also, the morphology of Ni/GO nanocomposites can be tuned by simply varying the metal loading. Morphology and specific surface area of the resultant Ni/GO nanocomposites were investigated by mean of AFM, HR-TEM and BET. Chemical sate and factual content of Ni in Ni/GO-1 and Ni/GO-2, and the presence of defective sites in Ni-nanocomposites were investigated in detail. To our delight, the prepared Ni/GO-2 demonstrated superior catalytic activity toward the reduction of 2- and 4-nitrophenol in water with high rate constant (kapp) of 35.4 × 10−3 s−1. To the best of our knowledge, this is the best efficient Ni-based graphene nanocomposites for the reduction of 2- and 4-NP reported to date. The Ni/GO-1 and Ni/GO-2 demonstrated an excellent reusability; no loss in its catalytic activity was noticed, even after 10th cycle. Surprisingly the Ni/GO-2 as electrode material exhibited an excellent specific capacitance of 461 F/g in 6 M KOH at a scan rate of 5 mV. Moreover, the Ni/GO nanocomposites were found to possess poor electrical resistance and high stability (no significant change in the specific capacitance even after 1000 cycles). Full article

Title: Understanding the Role of Al/Zr Ratio in Zr-Al-Beta Zeolite: Towards the One-Pot Production of GVL from Glucose
Authors: Gabriel Morales [email protected]
Abstract: The direct one-pot transformation of glucose into γ-valerolactone (GVL) can be accomplished by means of a cascade of reactions in which acid-catalyzed transformations are combined with catalytic transfer hydrogenation (CTH) by using 2-propanol as sacrificing alcohol, avoiding the use of high-pressure H2. Catalysts containing Zr species have been successfully applied in MPV reactions while the acid-driven transformations can be promoted by Brønsted Al-related acidity. The combination of Zr and Al as active sites within a BEA zeolite structure as catalyst is herein proposed, with the possibility of adjusting the Al/Zr ratio. In this research, different materials have been synthesized, tuning the Al/Zr molar ratio. The influence of this parameter on the catalytic performance is highly significant in the products distribution. Besides the main cascade transformation of glucose into GVL, the parallel retro-aldol condensation of the sugar to produce isopropyl lactate has also been detected. This side reaction is likewise favored by Zr sites. Within this study, we have proved that the bi-functional Zr-Al-Beta zeolite can be tuned to promote the one-pot cascade reaction of glucose into GVL in 2-propanol with a good performance.
