Dimethyl disulfide (DMDS) is a common odor pollutant with an extremely low olfactory threshold. Highly sensitive and selective detection of DMDS in ambient humid air background, by metal oxide semiconductor (MOS) sensors, highly desirable to address the increased public concern for health risk. However, it has still been critical challenge up now. Herein, p-type delafossite CuGaO2 proposed as promising sensing material owing its striking hydrophobicity (revealed water contact angle...
Recent advances in heterogeneous catalysts indicate that single atoms (SAs), anchored/stabilized on metal oxide nanostructures, exhibit not only high catalyst atom efficiency but also intriguing reactivity and selectivity. Herein, isolated Pt SA-anchored CuCrO2 (CCO) has been designed by a glycine-nitrate solution combustion synthesis (SCS) route. The density of SAs achieves the highest value ∼100 μm-2 for 1.39 wt % Pt-anchored CCO sample, which results drastically boosted H2S response...
As one of the bottleneck parameters for practical applications metal oxide semiconductor-based gas sensors, sensitivity enhancement has attracted significant attention in past few decades. In this work, alternative to conventional strategies designing sensitive surfaces via morphology/defect/heterojunction control (then operating at an optimized isothermal temperature with a maximal response), facile approach by decoupling surface charge exchange and resistance reading process (possessing...
Abstract Seeking a facile approach to directly assemble bridged metal oxide nanowires on substrates with predefined electrodes without the need for complex postsynthesis alignment and/or device procedures will bridge gap between fundamental research and practical applications diverse biochemical sensing, electronic, optoelectronic, energy storage devices. Herein, regularly CuO microhemisphere nanowire arrays (RB‐MNAs) are rationally designed indium tin via thermal oxidation of ordered Cu...
Synergetic effect of multiplying defects and reversible sulfuration–desulfuration reaction endows heterostructural CdS/SBO as a novel high-performance methyl mercaptan chemiresistor.
Abstract Although temperature modulation of a single (nonselective) semiconductor gas sensor has demonstrated its great capability on discriminating molecules, quantitative analysis the type and concentration structurally similar volatile organic compounds (VOCs) molecules remains significant challenge. In this work, as an alternative to oxide sensor, arrays composed four types NiO‐based synchronously perform thermal with unique programmed cooling profile. Apart from improved category...
The investigation of novel ternary metal oxide based breath acetone chemiresistors has garnered interest in a facile diagnosis diabetes via analysis. In this work, sodium dodecyl sulfate (SDS)...
A thermally evaporated hydrophobic PDMS membrane could significantly mitigate humidity interference/poisoning (without a decline in response at 50% RH for nearly 3 months) and enhance the selectivity of CuCrO2 chemiresistor toward erosive H2S, offering an avenue practical applications (H2S) chemiresistors ambient humid air atmosphere.
Though considerable progress has been achieved on gas molecule recognition by electronic nose (e-nose) comprised of nonselective (metal oxide) semiconductor chemiresistors, extracting adequate molecular features within short time (<1 s) remains a big obstacle, which hinders the emerging e-nose applications in lethal or explosive warning. Herein, virtue ultrafast (∼20 μs) thermal relaxation self-heated WO3-based chemiresistors fabricated via oblique angle deposition, instead external heating,...
UV photoactivation has been widely employed to trigger the response of semiconductor chemiresistors at room temperature (RT). Generally, continuous (CU) irradiation is applied, and an apparent maximal could be obtained via optimizing intensity. However, owing conflicting roles (UV) in gas process, we do not think potential fully explored. Herein, a pulsed light modulation (PULM) protocol proposed. Pulsed UV-on facilitates generation surface reactive oxygen species refreshes chemiresistors,...
Severe humidity interference or even poison, especially at room temperature (RT), poses a challenge for the practical application of metal oxide semiconductor (MOS)-based chemiresistors monitoring hazardous O3 vapor in real humid air background, owing to intrinsic hydrophilicity general MOSs. Herein, we demonstrated that humidity-tolerance performance an ultraviolet (UV)-activated ZnO chemiresistor (operated RT) toward could be drastically improved by facile H2O2 treatment. The onset poison...
