Synthesis and H2S gas-sensing properties of SnO2/ZnO core/shell structure

In the study, SnO2/ZnO core/shell nanowires were synthesized through the two-step processes. First, SnO2- core nanowires were synthesized from Sn powder source at 750 oC by a chemical vapor deposition method (CVD). The ZnO shell was then deposited on SnO2 nanowires by a DC sputtering method.
