Undoped and doped mesoporous silver/Co3O4 nanorods supported on stainless steel wire meshes were prepared using the ammonia-evaporation-induced method. In the paper the crystalline nature and phase purity of the as-prepared materials were investigated using X-ray diffraction (XRD) measurements. Morphological characterizations were performed using a scanning electron microscope (SEM). The band gap energies were estimated by UV-vis spectroscopy. The results for optical properties results showed an apparent decrease in the direct band gap energies with increasing Ag-content from 1.86 eV for pure Co3O4, to 1.58 eV for 24%Ag/Co3O4. The preferential oxidation CO reaction results showed that the undoped Co3O4 exhibits a good catalytic activity in the [170-195°C] temperature range, while the catalytic activity is weakly affected by the Ag-doping process. The enhanced optical properties lead to the possible use of said nanorods in photocatalytic and photovoltaic applications.
