Highly sensitive ethanol gas sensors based on Bi0.9Er0.1FeO3/In2O3 composites
In this study, Bi0.9Er0.1FeO3/In2O3 composites were prepared by sol-gel method. The structure, morphology, elemental valence and ethanol gas sensing performance were characterized and studied. At 330 °C, Bi0.9Er0.1FeO3/In2O3 composite sensor exhibits a response of 112 when exposed to 100 ppm ethanol, roughly 7 times higher than Bi0.9Er0.1FeO3. The response/recovery time of the sensor is 5 s/75 s, alongside good selectivity, anti-interference and stability. The improved performance in gas sensing may be ascribed to heterojunctions between Bi0.9Er0.1FeO3 nanoparticles and In2O3 nanoparticles. Meanwhile, Bi0.9Er0.1FeO3/In2O3 composites have larger specific surface area, which increases adsorption sites and supports reactions more effectively.
期刊介绍：
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
