Electrocatalysis by atomic catalysts is a major focus of chemical and energy conversion effort. Although transition-metal-based bulk electrocatalysts for electrochemical application on processes have been reported frequently, anchoring the stable transition-metal atoms (e.g. nickel iron) still remains practical challenge. Here we report strategy fabrication ACs comprising only isolated nickel/iron anchored graphdiyne. Our findings identify very narrow size distributions both (1.23 Å) iron...
Graphdiyne (GDY) is a flat material comprising sp2- and sp-hybridized carbon atoms with high degrees of π conjugation that features uniformly distributed pores.

Conjugated organic molecules are interesting materials because of their structures and electronic, electrical, magnetic, optical, biological, chemical properties. However, researchers continue to face great challenges in the construction well-defined compounds that aggregate into larger molecular such as nanowires, tubes, rods, particles, walls, films, other structural arrays. Such nanoscale could serve direct device components. In this Account, we describe our recent progress nanostructures...
