Summary: High-entropy alloy nanoparticles (HEA-NPs) are currently underutilized in heterogeneous catalysis due to the lack of a reliable, sustainable, and facile synthetic method. A novel synthesis method utilizing alcoholic ionic liquids (AILs) to promote the formation of HEA nanocatalysts has been developed, resulting in environmentally friendly alternatives to traditional reducing agents and solvents. Ultrasonic irradiation co-reduces and transforms Au3+, Pd2+, Pt2+, Rh3+, and Ru3+ ions into single-phase HEA (AuPdPtRhRu) nanocrystals without the need for calcination, showing superior catalytic performance compared to monometallic counterparts.

Summary: TiO2+Pt plasmonic solids with 1 wt% Pt and different TiO2 supports (anatase nanoparticles (TNP), polycrystalline nanorods (a-TNR) and single-crystal anatase nanorods (TNR)) were synthesized and tested as photo, thermal and photothermal catalysts. The formation of Pt particles with different sizes, crystallinities and degrees of interaction with the TiO2 supports was influenced by the charges of the TiO2 support surfaces. The TNR+Pt catalyst showed low visible-light-triggered photocatalytic activity but exhibited the highest photothermal catalytic H2-assisted NO2 reduction rate.

Summary: Alumina-supported RhSn alloy nano catalysts were prepared through sequential reduction method, resulting in the transformation of Rh@Sn core-shell nanoparticles into RhSn alloy on alumina. The Rh1Sn0.7/Al2O3 catalysts exhibited enhanced catalytic efficiency for toluene hydrogenation compared to Rh/Al2O3. A methyl cyclohexane yield of 99.2% was achieved at a toluene/Rh molar ratio of 118/1, 0.1 MPa H2 pressure, and 45°C within 2.0 hours. The improved catalytic efficiency of Rh1Sn0.7/Al2O3 can be attributed to the synergistic effect between Rh and Sn.

Summary: Lattice oxygen redox in solid-state material hosts is an emerging observation in electrochemistry. Activation of lattice oxygen in water electrolysis can significantly enhance the anodic oxygen evolution reaction (OER) kinetics, either by facilitating the nucleophilic attack of O-O coupling or through direct participation of lattice oxygen in gaseous O2 generation. Understanding the molecular-level mechanisms provides fundamental guidelines for advanced OER catalyst design. This review comprehensively discusses the correlation between band alignments and preferential OER mechanisms, recent progress in lattice oxygen activation, and remaining challenges and future prospects for electrocatalysis advancements.

Summary: Jagged Au-Pt bimetallic nanowires with abundant twin boundaries have been synthesized, and the lattice strain and electronic structures of Pt in the twin-rich nanowires have been tuned, resulting in the modulation of alcohol oxidation reaction (AOR) activities. The AuPt3 nanowires exhibit the highest mass activity for ethanol and methanol oxidation reactions, surpassing other nanowires and commercial Pt/C catalysts. The structure-activity correlation for AOR follows a volcano-shaped curve with increasing Pt ratios. This work provides a simple yet effective method to synthesize twin-rich bimetallic nanostructures with controlled lattice strain and illustrates their structure-dependent properties.
