Photosynthesis occurs through the synergistic effects of the non-ncontinuously distributed components in the chloroplast. Inspired by nature, we mimic chloroplast and develop a generic approach to synthesize non-continuously distributed semiconductors threaded by carbon nanotubes. In the synthesis, carbon nanotubes serve as microwave antennas to produce local super-hot dots on the surface, which might induce and accelerate various organic/inorganic semiconductors assembly. With the unique nanoscale designed bionic architecture, a chloroplast structured photocatalyst with 3-dimentional dual electron transfer pathways facilitate enhanced photocatalytic performance. The as-synthesized carbon nanotubes-titanium oxide achieves a record-breaking efficiency of 86% for nitric oxide treatment under ultraviolet light irradiation. As a general strategy, a wide variety of carbon nanotubes threaded chloroplast structured nanomaterials can be synthesized and these nanomaterials could find applications in energy chemistry, environmental science and human health.
光合作用通过叶绿体中不连续分布的成分的协同作用发生。受自然启发，我们模仿叶绿体并开发了一种通用方法来合成由碳纳米管贯穿的不连续分布的半导体。在合成过程中，碳纳米管充当微波天线，在表面产生局部超热点，这可能会诱导并加速各种有机/无机半导体的组装。凭借独特的纳米级设计仿生结构，具有三维双电子转移途径的叶绿体结构光催化剂有助于提高光催化性能。合成的碳纳米管-二氧化钛在紫外光照射下对一氧化氮处理的效率达到了创纪录的86%。作为一种通用策略，可以合成多种由碳纳米管贯穿的叶绿体结构纳米材料，这些纳米材料可在能源化学、环境科学和人类健康领域找到应用。
