During the last century, many semiconductor gas sensors have been presented based on various materials and technologies to detect gas components. Many of them are made to support human's life in different ways. In the last years, the number of sensors which can detect various gas species has increased dramatically especially with respect to global issues of environment and earth atmosphere, the necessity of those gas sensors which can detect air pollutants such as NO x gases in environment is felt. They are essentially required in order to control the systems of combustion exhausted from industry, stationary facilities and automobiles. So it is necessary for the scientists to design and fabricate the gas sensors which are of low cost, selective, sensitive, and accurate especially in low level concentrations of target gases, easy to process and of high recovery and response time, good electrical properties, and above all tunable structure at the nano scale. In this sense, this paper has presented various classifications of gas sensors and various semiconductor oxides for NO x detecting and their technology to convey a comprehensive idea about the semiconductor metals as well as metal oxides for NO x detecting along with their characteristics, structures etc. in order to clarify the future road map towards on the semiconductor materials for NO x detecting. Keywords: sensor, NO x gases, semiconductor, metal oxides INTRODUCTIONIn the last few decades, many studies have been focused on the semiconducting metal oxides which are known as effective gas sensing materials especially for NO x detecting due to their electrical conductivities which are open to change greatly with the changes of atmosphere (K. J. Choi & Jang, 2010;Comini et al., 2009;Fine, Cavanagh, Afonja, & Binions, 2010;Franke, Koplin, & Simon, 2006; Kanan, El-Kadri, Abu-Yousef, & Kanan, 2009; G Korotcenkov & Cho, 2011;J.-H. Lee, 2009;Tricoli, Righettoni, & Teleki, 2010;Wetchakun et al., 2011). The sensing characteristics of such sensors can be optimized by controlling their morphology, surface to volume ratio, and electrical properties. The developments in nanotechnology, fabrication methods, and synthesis provide a suitable atmosphere to construct those sensors with their mentioned sensing characteristics easier.

“…Gas chromatography is mainly used as offline experiment, and spectroscopy is only in the stage of laboratory study and has a long way for practical application. With the advantages of simple manufacture technique, low cost, long life, rapid response, and recovery time, semiconductor SnO 2 may be the most promising sensing technology for detecting and recognizing dissolved fault characteristic gases in transformer oil [12][13][14][15]. However, some limitations, like high operating temperature, unsatisfactory selectivity, and poor long-term stability, are still needed to be further improved [16][17][18][19][20][21].…”

Acetylene C 2 H 2 gas is one of the most important fault characteristic hydrocarbon gases dissolved in oil immersed power transformer oil. This paper reports the successful preparation and characterization of samarium oxide Sm 2 O 3 decorated tin oxide SnO 2 based sensors with hierarchical rod structure for C 2 H 2 gas detection. Pure and Sm 2 O 3 decorated SnO 2 sensing structures were synthesized by a facile hydrothermal method and characterized by XRD, FESEM, TEM, EDS, and XPS measurements, respectively. Planar chemical gas sensors with the synthesis samples were fabricated, and their sensing performances to C 2 H 2 gas were systematically performed and automatically recorded by a CGS-1 TP intelligent gas sensing analysis system. The optimum operating temperature of the Sm 2 O 3 decorated SnO 2 based sensor towards 50 L/L of C 2 H 2 is 260 ∘ C, and its corresponding response value is 38.12, which is 6 times larger than the pure one. Its response time is about 8-10 s and 10-13 s for recovery time. Meanwhile good stability and reproducibility of the decorated sensor to C 2 H 2 gas are also obtained. Furthermore, the proposed sensor exhibits excellent C 2 H 2 selectivity among some potential interface gases, like H 2 and CO gas. All sensing results indicate the sensor fabricated with oxide Sm 2 O 3 decorated SnO 2 nanorods might be a promising candidate for C 2 H 2 detection in practice.
