Tri-layered structure published on Nature Communications!

06 June, 2018


Hybrid nanostructures integrating electroactive materials with functional species, such as MOFs, COFs, complex, graphdiyne, carbon etc., are of great significance for both fundamental research and energy conversion/storage applications. Herein, hierarchical triple-layered nanotube arrays, which consist of hydrogen substituted graphdiyne (HsGDY) frameworks seamlessly sandwiched between an outer layer of Ni, Co co-doped MoS2 nanosheets and an inner layer of mixed NiCoS (Co9S8, Ni3S2), are directly fabricated on a conductive carbon paper. The elaborate triple-layered structure is demonstrated a decent hybrid electrode for energy conversion and storage, in which the organic HsGDY middle layer with a large π-conjugation system between the electroactive nanomaterials provides built-in electron and ion channels and is crucial for performance enhancement. The tri-layered structure provides a promising platform for advanced nanostructure-engineering of hierarchical multilayered nanostructures towards a wide range of electrochemical applications.
