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

Small, Год журнала: 2023, Номер 19(48)

Опубликована: Июль 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

Green, efficient, and controllable preparation of In2O3 uniformly modified MoS2 nanoflowers for methanol detection

Applied Physics Letters, Год журнала: 2025, Номер 126(5)

Опубликована: Фев. 3, 2025

In2O3 uniformly modified MoS2 (In2O3/MoS2) nanoflowers were synthesized via a green, efficient, and controllable normal-pressure microwave-assisted route subsequent calcination process, using as substrates. The In2O3/MoS2 nanoflower is composed of extremely thin nanosheets, among which nanoparticles are attached to the nanosheets. Numerous p–n heterojunctions oxygen vacancies present on surfaces nanoflowers. composites exhibited high sensitivity selectivity, along with rapid response recovery methanol vapor at 240 °C. sensors exhibit rates toward methanol, particularly notable time only 15 s for 100 ppm methanol. also demonstrate excellent stability reproducibility, remarkable selectivity This research presents promising approach future design preparation composite detection.
