Low-dimensional nanomaterials, due to their good light-harvesting ability, unique electronic structure and surface properties, are considered to be the most promising materials for constructing artificial photosynthesis systems. However, their structure-property-activity relationship, which should be beneficial for the structural design, is still being explored. We employ 0-dimensional quantum dots (QDs)and 2D covalent organic framework (COF) materials as models, and use advanced in-situ methods to capture important reaction intermediates and establish a reasonable photocatalytic reaction process, including H2 production from water and CO2 conversion. At the same time, the artificial photosynthesis performance of the corresponding nanomaterials can be rationally tuned by regulating their intrinsic structures. Representative Publications • Angew.
