Summary: Tungsten-based catalysts, including WO3 and H2WO4, can selectively cleave C-C bonds in sugar intermediates during the conversion of cellulose to ethylene glycol and propylene glycol. The catalysts undergo reduction to HxWO3 species during the reaction, which act as heterogeneous catalysts and are re-oxidized to WO3 upon exposure to ambient air after the reaction. The activity of WO3 is strongly dependent on its crystallite size and surface area.

Summary: The study investigated the adsorption and dissociation of ethanol on Pt/beta-Mo2C for catalytic H-2 production. Results showed that Pt modifies the lattice parameters of beta-Mo2C, affecting the Mo-Mo distances and chemical state of molybdenum and carbon. The presence of Pt increased the catalytic activity of beta-Mo2C for ethanol decomposition, demonstrating a higher production of H-2 at temperatures above 530 K.

Summary: Biorefineries utilize lignocellulosic biomass as a renewable energy source to produce 5-hydroxymethylfurfural (HMF), which can serve as a bridge connecting biomass raw materials to alternative fuels, chemicals, and materials. However, the conversion of biomass into desirable products requires a series of complex processes including deconstruction, catalytic conversion, separation, and purification.

Summary: In this study, a combined in silico and experimental approach was used to investigate the extraction of furfural and HMF in aqueous-organic biphasic systems. The experimental data were found to be in good agreement with the predictions from the COSMO-RS model, and a selective extraction of furfural was demonstrated using an additional extraction step. The molecular nature of preferential furfural extraction was rationalized using COSMO-RS sigma-profile analysis.

Summary: This study focuses on the hydrogenation of 5-hydroxymethylfurfural (HMF) in ethanol to produce 2,5-bis(hydroxymethyl)furan (BHMF) or 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF). The highest yields of 80% and 93% were achieved, respectively. These compounds serve as important precursors for ethoxylated biofuels. The synthesis of 2,5-bis(ethoxymethyl)furan (BEMF) and 2,5-bis(ethoxymethyl)tetrahydrofuran (BEMTHF) through etherification with ethanol was also explored, with the zeolite HZSM-5 (Si/Al=25) showing the highest yield of BEMF at 74%.

Summary: In this study, lignosulfonate (LS) was successfully introduced into MOFs structure as a carbon resource. A series of lignin-MOF derived catalysts (NinCo-MOF-LS) were prepared with different ratios of Ni and Co metals. The catalysts showed good catalytic performance in the selective hydrogenation of HMF to MFA. The coordination of lignosulfonate and MOFs provide a novel alternative for the utilization of lignin resource and the upgrading of biomass-derived chemicals.

Summary: Selective hydrogenation catalysts with low noble metal content were synthesized from two different molybdenum precursors, and the catalytic behavior was influenced by the acidity of the catalysts. Heating treatment of the carbon support before Pt deposition improved catalytic performance by enhancing Pt dispersion and reduction, leading to different selectivities due to varied acid properties.

Summary: A highly efficient ternary NiCoMn-layered double hydroxides (NiCoMn-LDHs) nanosheet catalyst with oxygen vacancy-rich properties has been developed for the electrooxidation of HMF and furfural to FDCA and FurAc, showing high yields and good faradaic efficiency. The mechanism for its superior performance lies in the exposure of more active sites with oxygen vacancies, promoting synergistic effects between HMF and furfural oxidation reactions.

Summary: This study develops a new method for fabricating polysiloxane-based, porous HIPE-templated materials (polyHIPEs) containing palladium by cross-linking of poly(hydromethylsiloxane) (PHMS) with 1,3,5,7-tetramethyl-1,3,5,7-tetravinylcyclotetrasiloxane (D-4(Vi)) in water-in-oil high internal phase emulsion (HIPE) with PdCl2 as the aqueous phase. The microstructure of the materials depends on the ratio of D-4(Vi) to PHMS and is influenced by the presence of PdCl2 in HIPE. The resulting polyHIPEs contain metallic Pd nanoparticles that strongly interact with the polysiloxane matrix they are dispersed in and exhibit fair selectivity in the hydrogenation reaction of phenylacetylene to styrene.

The effect of solvents with different dielectric constants on the morphology, size, and phase composition of iron oxide composites was examined. The research provides new insights into submicron particle formation during pulsed laser irradiation and proposes a mechanism for the growth of particles of different size and phase composition depending on the solvent.

Summary: In this study, three series of zeolite catalysts, including Co all-silica and Co Al-containing zeolites beta, were prepared for the selective oxidative dehydrogenation of propane to propylene. The incorporation of cobalt into the zeolite framework was successfully achieved using a two-step postsynthesis method, resulting in the formation of isolated framework pseudo-tetrahedral Co(II) species. The characterization of cobalt species at different cobalt content was performed using various techniques, such as NMR, FTIR, and DR UV-vis.

Summary: The research focused on the influence of BEA zeolite dealumination on the acid-base characteristics and catalytic performance of Zn-BEA compositions in propane dehydrogenation with CO2. The catalyst samples were prepared through a two-step post-synthesis procedure and characterized using various techniques. Full dealumination led to the formation of a mesoporous structure and decrease in acidity, resulting in enhanced selectivity and yield of propene. The results highlighted the advantages of using Zn-BEA catalysts in the presence of CO2 for producing the target olefin.

Summary: This study characterizes the nuclear quantum dynamics of hydrogen in Pd/cWO(3) using neutron Compton scattering and ab initio modeling. Neutron Compton scattering, with its deeply penetrating nature and high sensitivity, is a powerful tool for investigating hydrogen dynamics in bulk matrices. The analysis reveals three pools of hydrogen with different nuclear quantum dynamical behavior: hydrogen-terminated beta-palladium hydride, hydrogen in acid centers on the surface of the cubic phase of tungsten oxide, and quasi-free atomic hydrogen resulting from the hydrogen spillover process. The theoretical predictions obtained from ab initio modeling provide insights into the momentum distribution of the quasi-free atomic hydrogen. The picture of the local dynamics of the quasi-free hydrogen is consistent with the proton polaron model of hydrogen-induced coloration of bulk hydrogenated WO3.

Summary: For the first time, this study proposes the combined use of surface-enhanced Raman spectroscopy (SERS), tip-enhanced infrared (TEIRA) nanospectroscopy, and quartz crystal microbalance (QCM) for comprehensive qualitative and quantitative analyses of drug/metal nanocarrier conjugates. The study focuses on erlotinib, a drug used in non-small cell lung cancer therapy, and its interaction with silver nanoparticles (AgNPs) as drug carriers. The results show the strong connection between the drug and the NPs mainly through the phenylacetylene moiety. The QCM is used to prepare an AgNP monolayer and determine the amount of erlotinib molecules immobilized on the metal nanosurface, while TEIRA nanospectroscopy provides ultra-high spatial resolution to identify the drug/AgNP monolayer connection.
