摘要

There is a growing interest in developing efficient and economically viable hydrogen (H) sensors for the swift detection of leakage of H in areas where hydrogen is used. In the present study we have prepared palladium catalysed antimony doped tin dioxide by sonochemical process, as a H gas sensing material for 1000 ppm to 8% by volume H gas concentration. The electrical characteristics of the sensors before and after the H exposure show significant changes at different temperatures. The response even shows more than 86% at 300 °C towards 1000 ppm H gas in a selective manner.
