Abstract: Choosing suitable gas for the surface treatment of gas sensing elements is one of the important technologies on the surface modification of the gas sensing elements, In the present paper, H2Sgas sensing element has been treated with SO2 gas under different conditions by which both sensitivity and selectivity of the gas sensing elements have been improved considerably.

Key words: SO2 atmospheric treatment, Gas sensing characteristics, Surface modification
