Room temperature gas sensing properties of porous silicon/V2O5 nanorods composite

Preparation and room temperature NO 2 -sensing performances of n-porous silicon/n-WO 3 nanowires heterojunction

“…This indicates that the introduced n-WO3 NWs not only maintain the low operating temperature but also improve the sensitivity and selectivity to NO2 gas of n-PS. This is similar to the gas sensing characterizations for other PS/metal oxides-based gas sensors [34][35][36].…”

Enhanced 1-butylamine gas sensing characteristics of flower-like V2O5 hierarchical architectures

“…Vanadium oxide, as an n-type semiconductor with a band gap of 2.2 eV, has received large amounts of attention in the past few years. It can be applied in wide fields, such as lithium battery electrode [14,15], supercapacitors [16], selective catalytic reduction catalyst [17] and gas sensors [18][19][20][21], etc. Especially, V 2 O 5 hierarchical architecture materials have been widely reported such as V 2 O 5 nanorods self-assembled hollow V 2 O 5 microspheres [22], V 2 O 5 hierarchical microspheres [23], self-organized spherical nano-urchins [24] and nanoplates packed flower-like V 2 O 5 microspheres [25], etc.…”

INFLUENCE OF ANNEALING DURATION ON THE GROWTH OF V2O5 NANORODS SYNTHESIZED BY SPRAY PYROLYSIS TECHNIQUE

“…19 Similarly, RF magnetron sputtering technique has also been used to synthesize V 2 O 5 thin¯lm on silicon substrates. 20 Yan et al 21 fabricated V 2 O 5 NRs based gas sensors on porous silicon (PS) substrates at room temperature by using magnetron sputtering technique. It was found that the use of porous substrates improves the quality of the NRs gas sensors.…”

“…It was found that the use of porous substrates improves the quality of the NRs gas sensors. 21 In addition to these techniques, the spin coating technique has also been used to grow various types of NRs. 22 Spray pyrolysis is another useful technique for the growth of di®erent kinds of NRs.…”
