Summary: This study proposes a design strategy to regulate active hydrogen (Hads) production, achieving highly selective electrocatalytic conversion of biomass-derived 5-hydroxymethylfurfural (HMF) to 2,5-bis (hydroxymethyl)furan (BHMF). Rhodium (Rh) nanoparticles grown on Cu nanowires (RhCu NWs) catalyst is used, which accelerates water dissociation and facilitates Hads generation. The construction of an interfacial Hads-rich environment promotes the formation of BHMF and suppresses the formation of undesired dimers.

Summary: The conversion of 5-hydroxymethylfurfural (HMF) into value-added chemicals is a sustainable approach for utilizing renewable carbon sources. Ni1Mn5-LDH, inspired by the manganese framework in the oxygen evolving complex (OEC) in natural photosynthesis, has been developed as the most efficient Ni-based electrocatalyst for HMF oxidation to FDCA. With a faradaic efficiency of 97% at 1.4 V (vs. RHE), the yield of FDCA production reached 94.72%. The rate-limiting step during HMF oxidation was found to be the oxidation of the CH2OH group to the CHO group.

Summary: Co-Ru bimetallic nanoparticles were synthesized by co-reduction of Co(II) and Ru(III) salts using octan-1-ol as a solvent and mild reducing agent. The formation of stable nanoalloys required careful selection of reaction parameters and metal precursors. The particles with higher Ru content exhibited smaller size and better size dispersity. The bimetallic particles showed improved performance compared to their monometallic counterparts in acceptorless alcohol dehydrogenation.

Summary: Bulk (Mo2N) and supported molybdenum nitride (Mo2N/TiO2, Mo2N/CeO2) were synthesized by reduction-nitridation of bulk and supported MoO3 under a mixture of N2/H2. The crystallographic phase and degree of nitridation of molybdenum nitrides can be controlled by adjusting synthesis parameters, such as heating rate and final temperature. The final crystallographic phase of the nitride mainly depends on the temperature rate and gas hourly space velocity employed during the synthesis.

Summary: This study explores the use of novel Cu/ZnO/ZnAl2O4/PAAH hybrid nanomaterials as catalysts for glycerol hydrogenolysis. The structural properties of these materials, including specific surface area, Lewis acidity, sizes and dispersion of copper nanoparticles, were modulated through sol-gel processes. The presence of PAAH and aluminium during synthesis improved the dispersion and metal-support interaction. Optimization of the catalysts led to high conversions of glycerol and selectivity towards 1,2-propanediol. Furthermore, the catalysts showed recyclability potential after reactivation.

Summary: Understanding structure-property relationships is crucial for developing new materials with low thermal conductivity. We synthesise two new mixed-anion materials, Bi8CsO8SeX7 (X = Cl and Br), with low thermal conductivities measured at room temperature. These materials possess different structural features, such as bond strength hierarchies, vacancies, and rattling, which significantly inhibit phonon transport. The thermal conductivities along different crystallographic directions are affected differently due to these features, resulting in low thermal conductivities for the Bi8CsO8SeX7 materials.
