The key issue for industrial large‐scale hydrogen production by water electrolysis is developing environment‐friendly electrocatalysts that can work well at large current densities and low overpotentials. Thanks to the superior advantages of 2D graphdiyne (GDY) on chemical structure and the alkyne bond strong reductivity, the highly selective, in situ growth of the single‐crystal Pd (111) quantum...
The intrinsic catalytic activity and active sites of the catalyst originate from the interface efficient charge transfer. A 2D graphdiyne (GDY) layer grown on the surface of zeolitic imidazolate framework nanocubes (ZIFNC@GDY) forms a novel structure of a perfect “donor–bridge–acceptor” interface, in which the ZIFNC and GDY act as electron donor and acceptor, respectively, linked by the sp‐C–Co and...
Self‐active metal‐free graphdiyne (GDY) is used, which has a precise chemical structure, as a model carbon‐based metal‐free electrocatalyst to assess its activity in the hydrogen evolution reaction (HER) and to understand the origin of electrocatalytic performance at the atomic level. The studies reveal that the unusual electrocatalytic properties of GDY originate from its unique nanostructure, which...
