Abstract

Metal oxide nanomaterials were synthesized via Horizontal Vapor Phase Crystal Growth deposition. Fabricated crystals were characterized using SEM and EDX spectroscopy and were installed in a circuit complete with mini gas chamber where the target gas at varying quantity was allowed to interact with the sensing surface. The sensitivity of the fabricated prototype was tested to hydrogen sulfide (H2S) gas using voltage analysis. Voltage measurements were made to study the response of the metal oxide crystal to the molecules of Hydrogen Sulfide gas. Results denote that the synthesized Tin Oxide nanomaterial sensor substrate is more sensitive and responsive to H2S gas compared to the Zinc Oxide sensor substrate.
