Optimal Pt mesoporous layer modified nanocomposite film with highly sensitive detection of ethanol at low temperature

Xin Tian et al.

Summary: This study presents a novel method for improving the sensitivity and selectivity of detecting ethanol at low temperatures using a Pt mesoporous layer modified multi-layer TiO2/SnO2 nanocomposite thin film. The Pt mesoporous layer, prepared using simple sputtering techniques, showed the highest sensitivity to ethanol at 130 degrees Celsius. Through this method, gas sensing properties of the nanocomposite film can be significantly improved.

Magnetron co-sputtering optimized aluminum-doped zinc oxide (AZO) film for high-response formaldehyde sensing

Ming Zhang et al.

Summary: A thin film sensor based on aluminum-doped zinc oxide (AZO) prepared by magnetron co-sputtering technology showed excellent response to formaldehyde at an operating temperature of 240 degrees C. The sensor exhibited good sensitivity to formaldehyde ranging from 100 ppb to 3 ppm, and could detect as low as 50 ppb, with high reproducibility and selectivity over other gases.

Bi2WO6 nanoparticles-decorated ZnO nanosheets and their enhanced gas sensing properties

Pengdou Yun et al.

Summary: This study synthesized Bi2WO6/ZnO composite materials through hydrothermal route, reported for the first time its sensing characteristics to triethylamine, and found an excellent gas sensitivity at a relatively lower temperature. The enhanced gas sensitivity was attributed to the formation of Bi2WO6/ZnO heterojunction and their unique flower-like structures.

Humidity compensation based on power-law response for MOS sensors to VOCs

Meng Yan et al.

Summary: A compensation model for humidity in Metal oxide semiconductor sensors was proposed for detecting volatile organic compounds vapor. Water vapor was considered a reactant in the response, and a power law model was introduced. The model showed good verification in experimental systems and could be applied to electronic noses for improved recognition results.

Enhanced ethanol sensing properties of WO3 modified TiO2 nanorods

Bekzat Abdikadyr et al.

Summary: The study focuses on investigating gas sensing properties by synthesizing pristine and WO3-decorated TiO2 nanorods. Experimental results demonstrate that the heterostructure shows better sensor response towards ethanol at 200 degrees Celsius.Enhanced sensing properties are attributed to the heterojunction formation by decorating TiO2 NRs with WO3.
