Inspired by natural photosynthesis in an organized assembly, compact H2-evolving molecular devices, which tether sensitizer and catalyst modules in one single molecule, present an opportunity to overcome the diffusion limit required for multi-component molecular systems, and increase intramolecular electron transfer rates from the photoactivated unit to the catalytic center to improve H2-evolving efficiency. Thereinto absolutely noble-metal free H2-evolving molecular devices are of particular interest because they don't contain precious and scarce noble-metal based components. This Frontier article focuses specifically on the recent advances in the design, synthesis, and photocatalytic properties of all-abundant-element molecular devices for photoinduced H2 generation via intramolecular processes. Some challenges and suggestions for future directions in this field are also illustrated.
受自然界中组织有序的光合作用启发，紧凑型的 H2 产生分子器件将敏化剂和催化剂模块束缚在单个分子中，为克服多组分分子体系所需的扩散限制提供了机会，并提高了从光激活单元到催化中心的分子内电子转移速率，从而提高 H2 产生效率。其中，不含贵金属的 H2 产生分子器件特别引人关注，因为它们不包含基于贵金属的珍贵和稀缺组件。本文聚焦于通过分子内过程光诱导 H2 产生的全丰度元素分子器件的设计、合成及光催化性能的最新进展，并对该领域未来的发展方向提出了一些挑战和建议。
