Title : (0, 1 and 2) Dimensional hybrid architecture of the synthesized materials leads the smart sensing of the gaseous species at low / room temperature


A large number of scientists and researchers are paying their devotion in the development of gas sensors for the detection of toxic, hazardous, combustible and inflammable gases. Yet, few sensors are lagging behind in the wide range of their applicability due to some persistence of their limitations of sensing the gases below Threshold Limit Value (TLV), lack of selective nature to a particular gas among the presence of various gases, high cost, large response and recovery time, etc. All these features of the sensors mainly depend on and co-related with various architectures prepared during the synthesis of the materials, crystallite size, thickness of sensor, nature of activators and their concentrations, microstructures and nanostructures, operating temperature, etc. The disc type ultrasonicated microwave assisted centrifuge technique has been used in the synthesis of the materials at nanoscale in various dimensional architecture. The materials in the form of thick films are utilized as the gas sensing elements. The electrical behavior and gas sensing performance of the nanocomposites have been investigated in our laboratory. The efforts are made in the said direction to develop the smart gas sensors by using hybrid nanomaterials, viz. ZnO, Bi2O3, SnO2, MnO2, MnO2, etc. The co-relation of sensor performance with architecture, crystallite size and shape, operating temperature, gas concentrations, film thickness, type of activators and their concentrations, surface activation, etc. will be presented and discussed.
