Summary: A heterogeneous catalyst, MSnPTA, consisting of phosphotungstic acid (PTA) immobilized over SnO2 mesoporous material, was developed for fructose to HMF conversion. The MSnPTA catalyst exhibited large surface area and pore diameter, and its spherical shape with worm like structure facilitated the catalytic reaction. The uniform distribution of PTA over SnO2 resulted in high acidity of the catalyst, leading to high conversion of fructose to HMF. The yield of HMF increased with increasing amount of catalyst and temperature.

Summary: Understanding the formation pathways of soluble humins in the fructose-to-HMF dehydration catalyzed by solid acid is critical for the design of efficient heterogeneous catalysts for HMF synthesis. This study revealed three representative formation paths of soluble humins and identified the types of acids that contribute to each path. The optimal catalyst was found to have a low density ratio of medium-strong to weak Bronsted acids and a low density of strong Lewis acids, effectively inhibiting humin formation. These findings emphasize the importance of rational catalyst design to minimize undesired humin formation in HMF biorefinery.

Summary: Facile and efficient production of ultra-stable metal nanocatalysts based on strong metal-support interactions (SMSI) was achieved through ultrasonication in water at ambient conditions, which generated abundant active intermediates, Ti3+ ions, and oxygen vacancies to induce SMSI overlayer formation. The degree of encapsulation could be controlled by the reducibility of solvents and ultrasonication parameters. This approach can be extended to other metal oxide supports and noble metal nanoparticles, leading to enhanced performance in hydrogenation reactions and CO2 conversion.

Summary: We report polydopamine-derived carbons with tailorable sub-5 angstrom micropore orifices and larger microvoids for olefin/paraffin separation. The sub-5 angstrom micropores allow the entry of olefins while excluding paraffins, achieving precise discrimination. The larger microvoids enable high ethylene and propylene capacities under ambient conditions. This study opens an avenue to exploit the sub-5 angstrom micropores in carbon for desirable size-exclusion effect.

Summary: A new W6+-doped TiNb2O7 material with a nanoporous structure (NPTWNO) was prepared through an ionothermal synthesis-assisted doping strategy. The improved Li+ diffusion coefficient of NPTWNO suggests that the ionic-liquid-templated nanoporous architecture enhances Li+ diffusion kinetics. The doped W6+ successfully boosts the electronic conductivity by narrowing the conduction-valance bandgap, as revealed by the density functional theory computational study.

Summary: Developing a powerful bifunctional catalyst is crucial for achieving future carbon neutrality by reducing energy consumption in the chemical industry. This study synthesizes mesoporous zeolite-encapsulated palladium nanoparticles (Pd@meso-ZSM-5) using emulsification-demulsification and dry-gel transformation methods, which exhibit remarkable catalytic performance in the one-pot multiple tandem reaction of cyclic ketones to bicyclic alkanes. Unlike traditional two-step synthesis routes, Pd@meso-ZSM-5 efficiently produces bicyclic alkanes instead of monocyclic alkanes, due to the sufficient space for large molecular intermediates provided by mesoporosity and the promoting effect of the acid-Pd interface on intermediate conversion.

Summary: The methylation of imidazolium-based room temperature ionic liquids (RTILs) paired with [Tf2N](-) anion results in an unexpected increase in viscosity, while the viscosity decreases when the methylated imidazolium is paired with [B(CN)(4)](-) anion. The compensated Arrhenius formalism (CAF) is used to study the viscosity observations, focusing on the activation energy and entropy of activation. The results show that the activation energy increases with methylation for [Tf2N](-), but decreases for [B(CN)(4)](-).

Summary: The electrochemical deposition of rare earth metals at room temperature has gained increasing attention for its energy efficiency advantage over traditional processes. However, the formation of a passivating fluoride layer during electrolyte decomposition is often overlooked, leading to the rapid decay of deposition current and hindering practical application. To address this issue, a fluorine-free electrolyte utilizing borohydride anion was demonstrated, enabling efficient electrodeposition of rare earth metals without passivation effect. Synergetic effects between rare earth borohydride and lithium borohydride were observed, promoting dissociation and improving ionic conductivity and electrochemical performance.
