来源:ACS PublicationsMalonate ligands demonstrate versatility for intercalating metal complexes into layered rare-earth hydroxides (LREHs), enabling controlled tuning of coordination geometry and composition. As a proof of concept, a series of copper(II) malonate complexes with various substituents was synthesized and successfully intercalated into layered yttrium, europium, or terbium hydroxide at room temperature via anion-exchange reactions. The copper content in these hybrid materials increased in the order: butylmalonate X-ray spectroscopy (EDX), IR, UV–vis, and electron paramagnetic r...

Dual-Modified C–Ce–Mn2O3 Heterostructured Anode Catalytic Layer with Ultrastable OER Performance in Concentrated H2SO4 for Sustainable Nonferrous Metal Electrodeposition来源:ACS PublicationsMn2O3 emerges as a viable anode catalytic layer candidate for nonferrous metal electrodeposition, yet its industrial adoption is hindered by acid-triggered structural collapse and Mn3+ overoxidation. Here, we demonstrate a heterointerfacial engineering strategy that integrates carbon scaffolding with Ce-doped Mn2O3 (C–Ce–Mn2O3), achieving high stability in concentrated sulfuric acid (160 g·L–1) under agg...

Alkali Metal Substitution-Induced Structural Transformation for RbREP2Se6 (RE = Gd, Tb, Dy) with Second-Harmonic Generation Responses来源:ACS PublicationsRare-earth (RE) chalcogenides have been extensively studied as infrared nonlinear optical (NLO) materials, and they demonstrate high potential as candidates with integrated performances; however, the subgroup of RE chalcophosphates has been rarely studied. Herein, three new quaternary RE selenophosphates, RbGdP2Se6 (1), RbTbP2Se6 (2), and RbDyP2Se6 (3), were synthesized using the reactive flux RbI-assisted RExOy–B–Se solid-state method. They cr...

Near-Ultraviolet-Induced Narrow-Band Emission Phosphors Eu3+-Activated YCa4O(BO3)3 for Backlight-Display and White Light-Emitting Diodes来源:ACS PublicationsDeveloping red emission materials with high efficiency, good thermal stability, and high color purity remains a challenge for phosphor-converted light-emitting diodes (LEDs) and backlight displays. Herein, Eu3+-doped YCa4O(BO3)3 (YCOB) phosphors with narrow-band red light emission were designed to meet simultaneously the above targets. All samples have strong red emission with high color purity under near-ultraviolet (NUV) excitation. The te...
