“…And the 8% LaOCl-SnO 2 nanofibers exhibited an optimal response of 3.7 toward 1,000 ppm CO 2 at 300°C with response/recovery times of 24/92 s (Xiong et al, 2017). Karthik et al reported the sensing properties of tin oxide (SnO 2 ) and zinc oxide (ZnO) thin films deposited onto macroporous silicon (PS) substrates to CO 2 and found that the obtained SnO 2 /PS films showed the highest sensing response of 19 to 15 ppm CO 2 gas (Karthik et al, 2018). …”

Tin oxide SnO2-based gas sensors have been widely used for detecting typical fault characteristic gases extracted from power transformer oil, namely, H2, CO, CO2, CH4, C2H2, C2H4, and C2H6, due to the remarkable advantages of high sensitivity, fast response, long-term stability, and so on. Herein, we present an overview of the recent significant improvement in fabrication and application of high performance SnO2-based sensors for detecting these fault characteristic gases. Promising materials for the sensitive and selective detection of each kind of fault characteristic gas have been identified. Meanwhile, the corresponding sensing mechanisms of SnO2-based gas sensors of these fault characteristic gases are comprehensively discussed. In the final section of this review, the major challenges and promising developments in this domain are also given.

“…El efecto óptico de las películas de ZnO fue mediante mediciones de transmitancia tomadas en un rango de 350-850nm con ayuda de un espectrofotómetro UV-vis (VELAB, VE-5100UV). Mientras que las mediciones de sensado fueron tomadas usando un sistema de sensado previamente reportado [12] [13]. A continuación se muestra el diagrama esquemático de síntesis de ZnO mediante la técnica sol-gel.…”

In present work is reported the zinc oxide (ZnO) deposit on corning glass substrates at 400°C by sol-gel spin coating technique. The optical effect of ZnO films was analyzed by transmittance measurements taken with help of UV-vis spectrophotometer. All the films showed transmittance ˃85% in visible range. Gas sensing measurements were taken in presence of CO2 at 300°C with a concentration of 1000ppm. Results revealed sensitivities above 50% in presence of CO2.

“…Для получения многослойных структур с интегрированными мембранами, включающих слои макропористого кремния с поперечными размерами пор > 1 мкм и слои от 100 нм, в едином технологическом процессе необходимо использование высокоомного кремния [12,13]. Слои макропористого кремния с диаметрами пор от 800 нм служат структурой с развитой поверхностью для чувствительного материала наноструктурированного окисла металла [5,[14][15][16][17][18].…”

Multilayer integrated porous membranes in a monolithic frame were obtained. Porous membranes consist of macroporous silicon with pore diameters of up to 10 μm and channel silicon with channel diameters from 100 to 300 nm. A laboratory technology is proposed to formation of macroporous/channel silicon two-layer structures using high-resistance n-Si substrates (1 Ohm•cm). The mechanism of pore formation is discussed and how this mechanism affects the morphology of porous layers when formic acid and ammonium hydroxide are used as electrolytes.
