Ocimum sanctum Leaf Extract-Assisted Green Synthesis of Pd-Doped CuO Nanoparticles for Highly Sensitive and Selective NO2 Gas Sensors

Anit K. K. Ambedkar et al.

Summary: Palladium-doped copper oxide (Pd-CuO) nanoparticles were synthesized from Ocimum sanctum phytoextract and used for gas-sensing applications. The structural and morphological properties of Pd-doped CuO nanoparticles were studied, and the gas-sensing response of the nanoflake-based sensor was measured. The sensor exhibited excellent selectivity and stability towards NO2 gas.

Comparative study on surface states and CO gas sensing characteristics of CuO thin films synthesised by vacuum evaporation and sputtering processes

Debashrita Mahana et al.

Summary: CuO thin films were synthesized by thermal oxidation of Cu films deposited using vacuum evaporation and sputtering processes. The sputtered CuO film showed higher sensing response towards CO gas compared to the evaporated film, which can be attributed to smaller crystallite size, finer granular surface morphology, and higher surface presence of Cu2+ ions.

Investigation on gas sensing and temperature modulation properties of Ni2+ doped SnO2 materials to CO and H2

Li-Sheng Zhang et al.

Summary: Although metal oxide semiconductor sensors have many advantages, the quantification of mixed gas components is still difficult due to poor selectivity. This study investigated the effect of doping and temperature modulation on the adsorption and desorption characteristics, and found that Ni2+ doping can increase the response of CO and H-2, improve selectivity, and enhance the surface activity of gas sensing materials.

Room temperature sputtered nanocrystalline SnO2 thin films sensitized with Pd nanoparticles for high performance CO gas sensing application

Amit Kumar Gangwar et al.

Summary: The present work demonstrates that Pd sensitized nanocrystalline SnO2 thin films show great potential for the development of CO gas sensors. These sensors exhibit excellent response and selectivity to CO gas, along with fast response and recovery times. Additionally, the Pd sensitized SnO2 thin films remain stable even after long periods of storage.

Pt decoration and oxygen defects synergistically boosted xylene sensing performance of polycrystalline SnO2 nanosheet assembled microflowers

Yue Xing et al.

Summary: Hierarchical SnO2 microflowers assembled by polycrystalline nanosheets were successfully synthesized and decorated with Pt nanoparticles to improve gas sensing properties. Pt/SnO2 nanosheets exhibited higher response value and shorter response/recovery time compared to pure SnO2, attributed to the unique hierarchical structure and abundant oxygen defects induced by Pt-decoration.

Effect of post-oxidation processes and thickness of SnO2 films prepared by vacuum evaporation on CO gas sensing characteristics

Amit Kumar Mauraya et al.

Summary: This report discusses the effects of post-oxidation processes and thickness of SnO2 thin films on their physical properties and CO gas sensing characteristics. The results show that SnO2 films produced by direct-oxidation method exhibit higher CO sensitivity, with thinner films showing even higher sensitivity and selectivity towards CO gas compared to step-oxidized films.

A review on resistive-based gas sensors for the detection of volatile organic compounds using metal-oxide nanostructures

Riya Alice B. John et al.

Summary: The presence of toxic and harmful gases pose serious threats to human health and the environment. Selective detection of these gases, using metal-oxide-based nano-materials, is becoming increasingly important. While there is a thriving area for monitoring VOCs and combustible gases, research in gas detection is still relatively limited.

Hydrogen sensing characteristics of Pd-decorated ultrathin ZnO nanosheets

Jae-Hun Kim et al.

Summary: The study utilized pristine and Pd-decorated 2D ZnO nanosheets for hydrogen detection, showing positive effects of Pd decoration on response, sensing temperature, and selectivity. Gas sensing experiments demonstrated that the Pd-decorated nanosheet sensor successfully detected low concentrations of hydrogen gas and could also detect hydrogen in a gaseous mixture with benzene. Furthermore, the presence of Pd-ZnO heterojunctions, formation of PdHx, and high catalytic activity of Pd were found to contribute to the sensing enhancement of the Pd-decorated sensor.
