Selective Reduction Laser Sintering: A New Strategy for NO₂ Gas Detection Based on In₂O₃ Nanoparticles

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 31, 2025

Abstract This study introduces a novel strategy for fabricating flexible nitrogen dioxide (NO 2 ) gas sensors based on Indium Oxide (In O 3 nanoparticles (NPs) employing selective reduction laser sintering (SRLS) technology. The SRSL technology utilizes ultraviolet (UV) to precisely and rapidly create oxygen vacancy (OV) defects in In NPs. These vacancies (OVs) enhance the active adsorption sites contribute additional free electrons, significantly improving sensor performance at room temperature. demonstrate excellent response ( S = 460.9 10 ppm), rapid response/recovery times τ resp / reco 27/570 s), superior selectivity (response ratio > 400), addition robust resistance light humidity (under ppm‐level NO gas). also exhibit low detection limit (200 ppb), high signal‐to‐noise (94.8 dB), good long‐term stability (25 days). Moreover, under photo‐assisted conditions, recovery speed of is further improved. not only provides an innovative development high‐performance but broadens application potential direct writing (LDW) advanced materials fabrications.

Effect of CTAB on the Morphology of Sn-MOF and the Gas Sensing Performance of SnO2 with Different Crystal Phases for H2 Detection

Chemosensors, Год журнала: 2025, Номер 13(5), С. 192 - 192

Опубликована: Май 21, 2025

Herein, a facile strategy was proposed to enhance the gas sensing performance of SnO2 for H2 by regulating its crystalline phase composition. Sn-based metal–organic framework (Sn-MOF) precursors with different morphologies were synthesized introducing surfactant cetyltrimethylammonium bromide (CTAB). Upon calcination, these yielded either mixed-phase (orthorhombic and tetragonal, SnO2-C) or single-phase (pure SnO2-NC) nanoparticles. Structural characterization tests revealed that SnO2-C exhibited high response 7.73 100 ppm at 280 °C, more than twice SnO2-NC (3.75). Moreover, demonstrated faster response/recovery time (10/56 s), selectivity, ppb-level detection limit (~79 ppb), excellent long-term stability. Notably, although addition CTAB reduced specific surface area SnO2, resulting lower minimized oxygen exposure during facilitating formation heterostructure. In addition, calcination atmosphere (flowing air Ar) adjusted further investigate role crystal in performance. The results clearly superior performance, achieving higher sensitivity H2. These findings underscored critical engineering design high-performance materials.
