Abstract
Abstract Covalent organic frameworks (COFs) have shown great promise for photocatalytic hydrogen evolution via water splitting. However, the four‐electron oxidation of water remains elusive toward oxygen evolution. Enabling this water oxidation pathway is critical to improve the yield and maximize atom utilization efficiency. A Z‐scheme heterojunction is proposed for overcoming fundamental issues in COF‐based photocatalytic overall water splitting (OWS), such as inefficient light absorption, charge recombination, and poor water oxidation ability. It is shown that the construction of a novel 2D/2D Z‐scheme heterojunction through in situ growth of COFs on the O‐vacancy WO 3 nanosheets (Ov‐WO 3 ) via the WOC…
