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.

空心结构SnO2的无模板合成与生长机理及核壳型SnO2 @ ZnO的制备

氧化锌（ZnO）和氧化锡（SnO ₂）由于其带隙宽，高电子迁移率和热稳定性而广泛用于气体传感器和光催化。在此，通过改变前驱物浓度和合成时间来合成无模板的SnO ₂的中空结构，并研究其生长机理。此外，合成了由SnO ₂和ZnO制成的核-壳结构，这是两种金属氧化物之间形成的异质结构，以弥补SnO ₂的劣质性。
