Abstract Photocatalysis is a promising solution to global energy shortage and environmental problems. Inspired by photosynthesis, multicomponent heterostructured photocatalysts are extensively investigated, step‐scheme (S‐scheme) heterojunction has emerged as the theoretical basis for delineating charge transfer processes in predominant photocatalysts. However, specific pathway across an S‐scheme remains elusive from atomic/molecular perspective. Herein, it demonstrated that composed of imine‐based covalent organic frameworks nanostructured zinc oxide, interfacial Zn ─ N bonds formed between two components play critical roles gateway heterojunction, based on calculations, X‐ray absorption spectroscopy, photoelectron spectroscopy. Moreover, mechanisms enhanced elucidated using femtosecond transient This work provides new insights into molecular‐level understanding promoting applications artificial photosynthesis.
