Metal oxide nanomaterials from zinc oxide bulk powder and tin (II) oxide bulk powder were synthesized via Horizontal Vapor Phase Crystal Growth deposition technique. Fabricated nanocrystals were successfully deposited on a silica quartz tube and were used as the sensing element of a fabricated gas sensor. Both zinc oxide and tin oxide showed nanowire structures. This indicated a high surface-to-volume ratio which favors the adsorption of gases on the sensing element which increases the sensitivity of the device.
