formaldehyde

 [for-mal´dĕ-hīd]
a gaseous compound with strongly disinfectant properties. It is used in a 37 per cent solution (formaldehyde solution; also called formol or formalin) as a disinfectant and as a preservative and fixative for pathological specimens. The gas is toxic and carcinogenic.

formaldehyde

H2C=O, methanal Occupational safety A highly toxic, flammable gas that is highly irritating to the respiratory and conjunctival mucosa at concentrations > 2 ppm; formaldehyde is soluble in water and forms methylene bridges between denatured proteins. See Formalin.

Figure 7 shows the sensor responses of the sensor device upon exposure to various concentrations of methanal at a working temperature of 260[degrees]C.
In an attempt to investigate the selective detection behavior of NiO/[In.sub.2] [O.sub.3] sensors, the selectivity of samples against other interference gases was also discussed by measuring the response to 600 ppm methanal, ethanol, ammonia, benzene, toluene, and chloroform at 260[degrees]C (Figure 8).
In the current work, the chemical mechanisms of NiO/[In.sub.2][O.sub.3] sensors to methanal can be shown in the following reactions.
The proposed process of NiO/[In.sub.2][O.sub.3] and reaction mechanism of NiO/[In.sub.2][O.sub.3] sensors to methanal gas is shown in Figure 9.
The prominent increasing of methanal gas response effectuated by decorating p-type NiO petals with n-type [In.sub.2][O.sub.3] could be explained by the formation of abundant p-n junctions.
In summary, a highly sensitive and selective methanal sensor was designed via coating the petal-shaped p-type NiO onto the surface of n-[In.sub.2][O.sub.3] cubes.
