A New Approach towards Gas Sensing through A.C. Conductivity of Tin Oxide-Copper Oxide Composite
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 8
Abstract
Tin oxide- Copper oxide composites were synthesized by a hydrothermal method using tin chloride dihydrate and copper nitrate trihydrate as precursors in different molar ratios. The obtained powders were characterized by Xray diffraction and dielectric analysis. The average crystallite sizes were determined. The analysis exhibited a tetragonal phase for tin oxide and cubic phase for copper oxide. The microstructure of the composites were examined by the scanning electron microscopy. Optical properties were investigated by a UV-Vis absorption spectrophotometer. Good electrical response of the composites to cigarette smoke was observed in dielectric analysis, holding substantial promise for SnO2-CuO as a challenging material for novel sensing applications
