Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Lignin is a natural non‐toxic polyphenolic macromolecule, which shows inherent antioxidant and broad‐spectrum antibacterial activities. However, due to the low content and the high bond dissociation energy of phenolic hydroxyl groups (Ar‐O·H), its antioxidant and antibacterial activities are relatively weak, which limits its application as a ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In this work, In2O3 and three rare earth (RE)‐doped In2O3 composites (Ho, Yb, and Sm‐doped) were prepared via the hydrothermal method. Compared with In2O3 sensors, those fabricated from the three composite materials (RE–In2O3) exhibit varying degrees of enhanced response toward ethylene glycol (EG) gas. At 35% relative humidity (RH) and 250°C,

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT With the growing severity of volatile organic compounds (VOCs) pollution, metal‐organic frameworks (MOFs)‐derived materials offer a promising solution through efficient photothermal catalysis. In this paper, M‐MnOx (M = Cu, Ni, Co, Fe) catalysts derived from manganese‐based MOFs were successfully prepared by the sacrificial template method and
