Graphene materials have been widely explored for the fabrication of gas sensors because of their atom-thick two-dimensional conjugated structures, high conductivity and large specific surface areas. This feature article summarizes the recent advancements on the synthesis of graphene materials for this purp...
a giant leap in the development of graphene-based gas-sensing devices [24,41–57]. We can clearly see that the number of published papers on graphene-based gas sensors has sharply increased over the period from 2007, as shown in Fig.2. The first experiment focusing on the detection of ga...

Gas sensors can detect combustible, explosive and toxic gases, and have been widely used in safety monitoring and process control in residential buildings, industries and mines. Recently, graphene-based hybrids were widely investigated as chemiresistive gas sensors with high sensitivity and selectivity. ...

Such an approach could open a window for realization of a variety of highly sensitive and fast gas or liquid sensors based on graphene, for wide applications in biological, medical and chemical fields. 展开 会议名称: Ofs International Conference on Optical Fiber Sensors ...
The performance of ML graphene-based sensors can be improved by 1) building devices with the Fermi level near the Dirac point, EF,Dirac, 2) enhancing the adsorption probability f(x) and driving force (the gap between the defect Fermi level of a certain gas and the Fermi level of the ...
However, such typical gas sensors usually work at high temperature, which may lead to great power consumption. Besides, working at high temperature often brings about safety problems when explosive gases exist [18]. In2O3-carbon nanotube nanocomposites had been synthesized by our group and their ...
