Abstract

In this study, the H₂S gas sensing characteristics were evaluated using surface-modified SnO₂ microparticles by tip sonication. The surface-modified SnO₂ microparticles were synthesized using the following sequential process. First, bare SnO₂ microparticles were synthesized via a hydrothermal method. Then, the surfaces of bare SnO₂ microparticles were modified with Ti nanoparticles during tip sonication. The sensing characteristics of SnO₂ microparticles modified with Ti were systematically investigated in the range of 100–300^oC, compared with the bare SnO₂ microparticles. In this study, we discuss in detail the improved H₂S sensing characteristics of SnO₂ microparticles via Ti nanoparticle modification.
