A number of sensor architectures have been explored for developing selective gas sensors that are capable of discriminating between reducing and oxidising gases as well as amongst the gases that are either reducing or oxidising. There is an immense drive towards developing highly selective gas sensors for continuous environmental monitoring and in-line process control in both benign and hostile conditions. Some of the desirable essential features of a typical gas sensor are (1) the ability to discriminate between gases in a real mixture of gases at all temperatures, (2) fast response, (3) rapid recovery, (4) high sensitivity, (5) size, (6) manufacturability, (7) cost effectiveness, (8) signal reproducibility, (9) robustness of signal, (10) compatibility with data logging system and (11) wireless communication. Many of these aspects strongly depend on the synthetic chemistry, crystal structure, film thickness, particle size, porosity, morphology, composition and catalytic properties of the sensing material.This paper will attempt to illustrate how gas sensors research has evolved over the number of years with the advancement in physics and chemistry of materials and what does the future holds for the technology.","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76552637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the incorporation of hetero atoms such as boron and nitrogen in the non-siliceous materials can significantly change their electronic and semi-conducting properties. Firstly I will present some results about the discovery of the nanoporous carbon and nitride materials, and the basics and the mechanism behind the synthesis of various nanoporous nitride materials with different pore structure and textural parameters. Then, the preparation, characterization and the applications of one and three dimensional nanoporous carbon nitrides materials synthesized using various inorganic templates with the different pore structures (MCN-11,2 and MCN-23) through a simple polymerization reaction between ethylenediamine (EDA) and carbon tetrachloride (CTC) will be presented. Moreover, the methods to control the textural parameters and the nitrogen content of the nanoporous carbon nitride materials, which have been solely developed in my group, will also be discussed.4 Not only the powder materials but also the different ways for the fabrication of nanoporous carbon nitride nanoparticles and films with hierarchical ordered structure and morphology will be demonstrated. In addition, I will show some of the results on the preparation of nanoporous boron nitride (MBN) and boron carbon nitride (MBCN) which have been prepared by novel elemental substitution technique5 using nanoporous carbon as the template at very high temperature. In the last part of the talk, I briefly discuss about the different ways of preparing nanoporous carbon materials with various structure types, especially “Carbon Nanocage and Carbon Nanocoops”, and to tune the pore diameters and textural parameters. The applications of the materials including sensing of different molecules and biosensing will be discussed in detail.6−12","PeriodicalId":6431,"journal":{"name":"2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88275056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reveal the effect of indium concentration on the gas sensing characteristics, thin films were synthesized using different concentration of indium in the precursor. X-ray diffraction (XRD) study indicates formation of crystalline phase of zinc oxide under the prevailing experimental conditions. The scanning electron microscope (SEM) images reveal uniform deposition on the entire substrate surface characterized by granular morphology. A careful observation of the SEM images reveals that nanocrystalline nature of the films, with average grain size ∼ 300 nm. The elemental composition obtained from the Energy Dispersive X-ray Analysis (EDAX) confirms presence of indium along with zinc and oxygen in the synthesized thin films. The gas sensing characteristics of the In-ZnO2 films were investigated for Liquefied Petroleum Gas (LPG) vapours at different operating temperatures in the range of 200 to 320 °C and various vapour concentration values. Interestingly, the In-ZnO thin films exhibited good sensor response in the operating temperature range. The response and recovery times are also in the range of few tens of second.
