Synergistic Effect of Electron Scattering and Space Charge Transfer Enabled Unprecedented Room Temperature NO₂ Sensing Response of SnO₂

Small, Journal Year: 2023, Volume and Issue: 19(48)

Published: July 4, 2023

Metal oxide gas sensors have long faced the challenge of low response and poor selectivity, especially at room temperature (RT). Herein, a synergistic effect electron scattering space charge transfer is proposed to comprehensively improve sensing performance n-type metal oxides toward oxidizing NO2 (electron acceptor) RT. To this end, porous SnO2 nanoparticles (NPs) assembled from grains about 4 nm with rich oxygen vacancies are developed through an acetylacetone-assisted solvent evaporation approach combined precise N2 air calcinations. The results show that as-fabricated NPs sensor exhibits unprecedented -sensing performance, including outstanding (Rg /Ra = 772.33 @ 5 ppm), fast recovery (<2 s), extremely detection limit (10 ppb), exceptional selectivity (response ratio >30) Theoretical calculation experimental tests confirm excellent mainly attributed unique transfer. This work proposes useful strategy for developing high-performance RT using oxides, provides in-depth understanding basic characteristics on sensing, paving way efficient power consumption

Nanorods Assembled Hierarchical Bi2S3 for Highly Sensitive Detection of Trace NO2 at Room Temperature

Chemosensors, Journal Year: 2024, Volume and Issue: 12(1), P. 8 - 8

Published: Jan. 4, 2024

The bismuth sulfide nanostructure has become a promising gas sensing material thanks to its exceptional intrinsic properties. However, pristine Bi2S3 as room-temperature cannot achieve the highly sensitive detection of ppb-level NO2 gas. Herein, 1D nanorods with self-assembled hierarchical nanostructures were obtained via simple hydrothermal process. as-prepared exhibited outstanding behaviors, such high response value (Rg/Ra = 5.8) and short response/recovery time (τ90 28/116 s) upon exposure 1 ppm NO2. limit was down 50 ppb. Meanwhile, sensor excellent selectivity humidity tolerance. improved properties associated nanostructures, which provided rich active surface accelerated diffusion adsorption/desorption processes between molecules materials. Additionally, is much higher at 100% N2 atmosphere, different from chemisorption oxygen model.

Detecting trace-level nitrogen dioxide (NO2) in real time is critical due to its adverse impact on human health and the environment. However, achieving a fast response, high sensitivity selectivity, excellent stability NO2 detection remains challenge. Two-dimensional (2D) metal chalcogenides are promising for gas sensing, but their practical use thwarted by issues like insufficient recovery poor stability. As an alternative, it anticipated that 2D oxychalcogenides, emerging class of gas-sensing semiconductor materials, offer favorable characteristics.
