A Comparative Study on the Photocatalytic and Gas Sensing Properties of Pure and N-doped TiO sub(2) thin Films

A correlation between the photocatalytic efficiency and gas sensitivity has been attempted on pure and N-doped TiO sub(2) thin films prepared by pulsed DC magnetron sputtering. The physical properties are studied. The gas sensing behavior in pure and nitrogen doped TiO sub(2) thin films could be rea...

Description
Summary:	A correlation between the photocatalytic efficiency and gas sensitivity has been attempted on pure and N-doped TiO sub(2) thin films prepared by pulsed DC magnetron sputtering. The physical properties are studied. The gas sensing behavior in pure and nitrogen doped TiO sub(2) thin films could be realized at low temperature. The measurements start at 130 degree C. The nitrogen doped TiO sub(2) (3sccm) has no sensitivity for oxygen. All sensors have sensitivity to hydrogen. If the temperature is increased the sensitivity is increased. All samples show photocatalytic activity. The photocatalytic and gas sensing properties have no significant correlations.
