Qingwu Huang,Shouqin Tian,Dawen Zeng,Xiaoxia Wang,Song Wulin,Yingying Li,Wei Xiao,Changsheng Xie +7 more
TL;DR: In this paper, a chemically bonded TiO2/graphene composites with a chemically-bonded interface were prepared by a facile solvothermal method using tetrabutyl orthotitanate (TBOT) as the Ti source.
Journal ArticleDOI
Metal-oxide-semiconductor based gas sensors: screening, preparation, and integration
TL;DR: It was concluded that the material-sensor integration was also introduced to maintain the structural stability in the sensor fabrication process, ensuring the sensing stability of MOS-based gas sensors.
Journal ArticleDOI
In situ synthesis of C-TiO2/g-C3N4 heterojunction nanocomposite as highly visible light active photocatalyst originated from effective interfacial charge transfer
TL;DR: In this paper, a simple one-pot hydrothermal strategy was adopted to prepare C-TiO2/g-C3N4 nanocomposite, which achieved the highest photocatalytic activity.
Journal ArticleDOI
Room temperature formaldehyde sensors with enhanced performance, fast response and recovery based on zinc oxide quantum dots/graphene nanocomposites
TL;DR: The proposed gas sensing mechanism is experimentally proved by DRIFT spectra results and has potential applications for monitoring air pollution, especially for harmful and toxic VOCs (volatile organic compounds).
Journal ArticleDOI
Solution-Processed Gas Sensors Based on ZnO Nanorods Array with an Exposed (0001) Facet for Enhanced Gas-Sensing Properties
TL;DR: In this article, a solution-processed ZnO nanorod array is synthesized on the sensor surface by a facile solution-processing technique, showing that the surface structure at the atomic level is a key factor in improving the oxygen adsorption and, consequently, the gas-sensing performance.
