【 摘 要 】

tsAtomically dispersed Zn-anchored 3D sponge-like polymeric carbon nitride (Zn-PCN) characteristic of a unique Zn-N6 electron-deficient configuration is synthesized via an intermediate coordination strategy.The electron-deficient Zn-N6 configuration contributes to enhanced electron excitation, accelerated charge separation and transfer as well as reduced overpotentials of water redox reactions.The obtained Zn-PCN realizes photocatalytic overall water splitting to stoichiometrically produce H2 and O2 with good durability under visible light.
