H2 Sensing Performances of Ag2O/CO3O4 Composites

In this work is reported the synthesis of Ag
2
O loaded Co3o4nanocomposites using a simple chemical process and their gas sensing properties toward hydrogen. XRD and SEM-EDX characterization techniques were employed to investigate the influence of Ag
2
O on the structural and morphological characteristics of the Ag20-CO
3
O
4
composite nanoparticles synthesized. Gas sensing tests demonstrated that the Ag2O-CO
3
O
4
composite has better hydrogen sensing performance at mild temperature (125°C) than pure Co3o4.
