Bimetallic Metal–Organic Framework-Derived Fe2O3/In2O3 Nanotubes for the Detection of Triethylamine
Source abstract
Abstract
Metal–organic frameworks (MOFs) are ideal sacrificial templates and precursors with specialized micro- and nanostructures. In this paper, bimetallic MOFs-derived Fe 2 O 3 /In 2 O 3 composites were proposed for detecting triethylamine (TEA) gas with high sensitivity and low working temperature by a simple one-step oil bath method. The samples were analyzed by XRD, SEM, TEM, and XPS for structural morphology and chemical state, and their gas performance was investigated. The findings demonstrate that Fe 2 O 3 /In 2 O 3 nanotubes exhibit remarkable sensitivity to TEA gas. The response value to 5 ppm of TEA gas is 6250 at 100 °C, which is 11.4 times higher than that of In 2 O 3 . The enhanced sensing performance can be attributed to the generation of additional chemical absorbed oxygen and the formation of heterojunctions, as evidenced by experimental and density functional theory (DFT) calculations.
