Tunable High Entropy Lanthanide Oxide Microspheres via Confined Electroprecipitation in Emulsion Droplet Scaffolds.

ABSTRACT: Emergent high entropy nanomaterials and their associated complex surface structure hold promise to unlock unique catalytic intermediate pathways and photonic/plasmonic interactions; however, synthetic strategies to tune the size, morphological, and stoichiometric properties remain limited. This work demonstrates a confined electro-precipitation mechanism for the formation of tunable, high-entropy oxide microspheres within emulsion droplet scaffolds. This mechanism complements a traditional confined electrodeposition mechanism and explains the previously observed anomalous formation of thermodynamically unfavorable particles, including lanthanide species. Mass transfer studies reveal that microsphere coverage over a surface may be tuned and modeled by using a time-dependent modified Levich
