hydrogen gas. The sensor shows an e

hydrogen gas. The sensor shows an excellent response towards the
low as well high detection range of 10–10,000 ppm, respectively, at
a very fast response/recovery time of a few seconds to few minutes.
Fast response, stability, selectivity, low temperature operation and
reproducibility make this sensor excellent as compared to the sensors
reported in the literature. The films are stable over 4 months
and can be used many times without affecting the sensing effi-
ciency. Hence, the application of these films is promising as simple,
robust, and cost-effective for low detection of hydrogen
