Abstract
Hydrogen sensing materials and their device developments are recent interests due to their potential importance. A chemiresistive type of sensor with N-doped ZnO nanomaterial has been developed for hydrogen sensing. N-doped ZnO nanomaterials were synthesized using a facile wet chemical strategy. XRD patterns indicated a decrease in the crystal size of the hexagonal wurtzite structure for ZnO. Morphological studies on the particulates of N-doped ZnO also indicated a change in the rod-like structure. Visible region functioning of the nanomaterials has been verified spectroscopically for absorption, and reduced band gap values in the N-doped ZnO have been noted. With N-doped ZnO nanomaterials, gas sensing performance resulted in better hydrogen sensing ability (73%).
