Different nano-structured solid materials with well-defined micro-, meso-, and hierarchical porosity and controlled catalytic properties (acid/base, redox) are capable of catalyzing a wide range of chemical reactions (e.g., oxidations, reductions, acid/base processes, etherifications, condensations, etc.) in the liquid and gas phases, interesting for the industrial production of chemicals, fuels, energy and energy vectors. The presence of isolated metallic species, homogeneously distributed in the form of nanoparticles on specific acid/base supports or adequately incorporated in the inorganic framework of well-structured materials, provides multi-functional capacities to afford catalytic transformations and multi-step reactions in “one-pot” or “cascade-type” processes, thus reducing reaction steps and operations costs and making processes more efficient and sustainable.
This Special Issue welcomes contributions devoted to the design, characterization, and application of novel nano-structured catalysts for sustainable chemical processes, mainly those focussed on the production of renewable energy and fuels or those related to the transformation of renewable raw materials, such as biomass and its derivatives into valuable products.

Abstract: Au, Pt and Pd supported on ZSM-11 microporous zeolite was investigated as catalysts for glycerol oxidation towards higher value-added products. ZSM-11 was synthesized by hydrothermal treatment at 140° C in autoclave. Subsequently, ion exchange with NH4Cl 1M was performed to recover acidic sites and then, Au, Pt and Pd were incorporated onto this material by wet impregnation at 80° C. Finally, thermal treatment of desorption and calcination at 500 °C was carried out. These materials were characterized by different techniques as XRD, ICP, TEM- XEDS, XPS and then, these were evaluated in glycerol oxidation reaction in alkaline medium by employing oxygen pure as oxidizing agent. The maximum conversion of glycerol (57%) was reached over the Pt–ZSM-11 catalyst with selectivity higher than 50% towards lactic acid in mild reaction conditions. The optimal reaction conditions were studied to maximize the selectivity towards this important product. Catalytic tests were carried out to find the optimal reaction conditions that maximize selectivity to LA, modifying temperature, reaction time and NaOH/GLY ratio.

Abstract: In this work, ZnO unmodified (Cux/ZnO-0) and ZnO (Cux/ZnO-z) modified by high energy ball milling, were used as support for copper nanoparticles. The prepared samples were fully characterized by XRD, SBET, SEM-EDS, FT-IR, AA, Raman, isopropyl alcohol decomposition reaction of, CO2-TPD, XPS, RTP, N2O chemisorption and O2-TPD. The effect of high energy ball milling on the structural and physicochemical properties of ZnO were studied. Furthermore, these modifications introduced in the support were related to the size of metallic particles, their dispersion and the metal-support interaction, for each copper compositions. Both catalytic systems were evaluated in the oxidation of glycerol in liquid phase. The stability of copper nanoparticles under reaction conditions were studied by reuse cycles.
