Carbon materials have rapidly grown as highly promising candidates to replace noble metal catalysts in energy storage/conversion technologies. In this work, a strategy of hydrogen‐bonding triggered assembly to configure hollow carbon nanosheets by applying Silicalite‐1 as a substrate in the aqueous solution of dopamine is reported. Remarkably, the combined density functional theory modelling and experimental verification present a molecule/nano‐scale insight into the nature of the bonding behavior during the fabrication process. It is demonstrated that the SiOH on the surface of Silicalite‐1 acts as an anchor and that it is energetically favorable to pre‐adsorb the building blocks of polydopamine by hydrogen‐bonding, which triggers the subsequent assembly. As an example, the as‐prepared hollow carbon nanosheets with unique structure can efficiently catalyze tri‐iodide reduction and a power conversion efficiency up to 8.58%.

氢键触发组装，可配置空心碳纳米片以高效还原三碘化物

碳材料已迅速成长为在储能/转化技术中替代贵金属催化剂的极有前途的候选材料。在这项工作中，报道了通过在多巴胺水溶液中使用Silicalite-1作为底物的氢键触发组装策略来配置空心碳纳米片。值得注意的是，结合的密度泛函理论建模和实验验证为制造过程中键合行为的性质提供了分子/纳米尺度的见解。据证实，在Si Silicalite-1表面的OH起到锚点的作用，并且通过氢键预吸附聚多巴胺的结构单元在能量上是有利的，这会触发随后的组装。例如，制备的具有独特结构的中空碳纳米片可以有效催化三碘化物的还原，功率转换效率高达8.58％。
