Here we report multilayer hollow spheres consisting of alternating ultrathin Ti0.91O2 nanosheets and CdS nanoparticles via exquisite layer-by-layer self-assembly to achieve an all solid-state Z-scheme system with 7-times enhancement of the CH4-production rate relative to pure Ti0.91O2 hollow spheres, due to a greatly prolonged lifetime of charge carriers.
在此，我们通过精巧的层层自组装报告了由交替的超薄 Ti0.91O2 纳米片和 CdS 纳米颗粒组成的多层空心球，以实现全固态 Z 型体系，与纯 Ti0.91O2 空心球相比，CH4 生成速率提高了 7 倍，这归因于载流子寿命的大大延长。
