We present a novel bionanocatalyst fabricated by the adsorption–reduction of metal ions on polyurethane/S-layer protein biotemplate. The bioinspired support was obtained adsorption S-layer proteins (isolated from Lentilactobacillus kefiri) polyurethane particles. Silver and platinum nanoparticles were well-loaded surface after combination with metallic salts reduction H2 at room temperature. Transmission electron microscopy analysis revealed strawberry-like morphology bionanocatalysts...
In this work, the liquid-phase chemoselective hydrogenation of furfural was studied, employing Pt, Rh and Ni-based catalysts. Bimetallic systems, containing different amounts tin, were obtained by means controlled surface reactions between a monometallic catalyst Sn(C4H9)4. The results when catalysts employed suggest relationship metal properties activity selectivity obtained. All systems allowed obtaining furfuryl alcohol with high (99, 97 76% achieved Ni catalysts, respectively). addition...
Abstract This paper describes the preparation and characterization of MgO ZnO-based catalysts, pure mixed in different proportions, supported on γ-Al 2 O 3 . Their catalytic performance was studied transesterification soybean oil castor with methanol butanol, attempting to produce biodiesel. XRD (X-ray diffraction), SEM–EDS (scanning electron microscopy–energy dispersive X-ray spectroscopy), CO -adsorption N allowed characterizing prepared catalysts. The results were all cases consistent...
In this work, well-defined silica-supported Pt and PtSn catalysts were prepared by surface organometallic reactions characterized EXAFS-XANES at the L2,3 edge XPS of 4f Sn 3d levels. These tested in catalytic hydrogenation cinnamaldehyde liquid phase. results showed that PtSn−OM* (not having butyl groups anchored on surface), tin was present as Sn(0) adatoms "decorating" metallic surface, isolating atoms; PtSn−OM catalyst (Bu remain grafted found form Sn(II, IV) similar proportions. EXAFS...
The use of tomato plant residues (i.e., stems, leaves, etc.) as a substrate for catalytic pyrolysis biomass was investigated. A comprehensive study conducted to investigate the impact catalysts on performance different fractions gas, biosolid, waxes, and bioliquid) well distribution products within bioliquid. employed in this were derived from two distinct types zirconia. first type synthesized by conventional sol-gel method, while second prepared with modified method aimed at improving...
The superficial properties of different Pt/γ-Al2O3 catalysts, modified by the addition tin and/or lithium, were studied X-ray photoelectron spectroscopy (XPS), scanning electron microscopy, BET, and 2-propanol transformation. results obtained correlated with behavior catalysts in applied reactions such as dehydrogenation isobutane. To obtain very well defined bimetallic phases, was introduced means surface organometallic chemistry on metals techniques nature bimetallic-active sites so...
Research on nanoparticles obtained biological supports is a topic of growing interest in nanoscience, especially regarding catalytic applications. Silver (AgNPs) have been studied due to their low toxicity, but they tend aggregation, oxidation, and stability. In this work, we synthesized characterized AgNPs supported S-layer proteins (SLPs) as bidimensional regularly arranged biotemplates. By different reduction strategies, six variable sizes were two SLPs. Transmission electron microscopy...
A series of monometallic and bimetallic Pt PtSn catalysts, modified or not by the addition Li, was studied in dehydrogenation isobutane to isobutene reaction. Special emphasis devoted behavior catalysts obtained following different preparation procedures. In relation lithium, a strong dependence catalytic properties on order which Li added observed. Two alternatives were analyzed: (a) support adding lithium onto it, then it impregnated with metallic precursors; (b) precursors afterward...
