Abstract

Zinc oxide (ZnO) and tin oxide (SnO₂) are widely used in gas sensors and photocatalysis owing to their wide bandgaps, high electron mobilities, and thermal stabilities. Herein, a hollow structure of SnO₂ is synthesized without a template by varying the precursor concentration and synthesis time, and its growth mechanism is studied. In addition, a core-shell structure fabricated with SnO₂ and ZnO, which is the heterostructure formed between the two metal oxides, is synthesized to compensate for the inferior properties of SnO₂.
