Solid state gas sensors have proved to be verypromising for monitoring the emission of airpollutant and toxic gases because they are a low cost element. Titanium dioxide (TiO2) is metal oxide semiconductor.TiO2 has been extensively studied owing to its wide range of applications which include photo catalysis, heterogeneous catalysis, energy storage, solar cell components, corrosion-protective coatings, optical coatings and gas sensing.The obje...

The work is interdisciplinary as it involves environmental, physical and chemical principles. Semiconducting metal oxide sensors are one of the most widely studied groups of chemiresistive gas sensors. These sensors are designed to react with one class of gases whereby the SMO undergoes reduction and oxidation. This process causes the SMO sensors to exchange electrons with the target gas at a certain characteristic rate, thereby affecting the ...
