Gas sensor material Tungsten trioxide WO3 nanopowders
Hongwu nanometer is professional manufacturer and supplier for Tungsten oxide wo3 nanopowders in small quantity for researchers and in bulk order for industry groups.
Tungsten oxide wo3 nanopowders,size 50nm, purity 99.9%,color:yellow, bule and purple powder.
Tungsten oxide wo3 nanopowders is a good catalyst,the main catalyst and auxiliary catalyst are both ok, and it has higher selectivity in the reaction.Tungsten oxide wo3 nanopowders has very strong absorption ability to electromagnetic wave, can be used as a good solar absorption materials and recessive materials. wo3 nanopowders is a kind of n-type semiconductor materials, has good gas sensitive resistance,especially sensitive to NOX, H2S, NH3, H2,O3, so WO3 is widely used for gas sensor and color components.
This newest reports is about the fabrication and characterization of hydrazine amperometric sensor based on tungsten oxide (WO3) nanopowders.The fabricated hydrazine sensor exhibited a good sensitivity of 0.18,471 μA/μM/cm2 and detection limit of 144.73 μM. Importantly, to the best of our knowledge; this is the first report in which WO3 nanopowders are efficiently used as effective electron mediator for the fabrication of sensitive hydrazine amperometric sensor.
