Abstract

Palladium and palladium alloys (nickel, cobalt and nickel co-substituted) were prepared using low temperature chemical reduction technique at 300 K. The synthesized metal and alloys were deposited using PLD on alumina substrate. The deposited nanostructured thin film alloys showed much better sensitivity towards hydrogen between the concentrations of 2000 and 20000 ppm of hydrogen than pure palladium thin film at 300 K.
