La(FeCuMnMgTi)O High-Entropy Oxide Nanoparticles as Highly Efficient Catalysts for Solvent-Free Aerobic Oxidation of Benzyl Alcohol.

In this work, a solid-state method for the synthesis of perovskite La(FeCuMnMgTi)O high-entropy oxide (HEO) nanoparticles is detailed. Additionally, the high performance of these nanoparticles as catalysts in the aerobic and solvent-free oxidation of benzyl alcohol is demonstrated. The structural features of HEO nanoparticles are studied by X-ray diffraction and high-resolution transmission electron microscopy.

High-Entropy La(FeCuMnMgTi)O Nanoparticles as Heterogeneous Catalyst for CO Electroreduction Reaction.

In this work, La(FeCuMnMgTi)O HEO nanoparticles with a perovskite-type structure are synthesized and used in the electrocatalytic CO reduction reaction (CORR). The catalyst demonstrates high performance as an electrocatalyst for the CORR, with a Faradaic efficiency (FE) of 92.5% at a current density of 21.
