Graphynes (GYs), as a novel carbon allotrope, are composed of sp- and sp2-hybridized atoms. Among them, graphdiyne (GDY) is the most widely studied has received great attention. Its unique sp-hybridization, uniform pores, highly conjugated structures, especially GDY with high crystallinity, bring excellent electronic, optic, mechanical characteristics, making them extensively used in electronic devices, energy storage conversion, catalysis, gas separation, seawater desalination, so on. However, materials still face challenges, including synthesis crystalline rapid non-destructive characterization methods. In this review, we primarily summarize design, synthesis, structural high-crystallinity GDY. Various applications also described, which may new opportunities for single-crystalline materials.

Controlling the precise growth of atoms is necessary to achieve manipulation atomic composition and position, regulation electronic structure, an understanding reactions at level. Herein, we report a facile method for ordered anchoring zero-valent platinum manganese with single-atom thickness on graphdiyne under mild conditions. Due strong incomplete charge transfer between metal atoms, formation clusters nanoparticles can be inhibited. The size, structure bimetallic nanoplates are precisely controlled by natural structure-limiting effect graphdiyne. Experimental characterization clearly demonstrates such fine control process. Electrochemical measurements show that active site platinum-manganese interface guarantees high catalytic activity selectivity (~100%) alkene-to-diol conversion. This work lays solid foundation obtaining high-performance nanomaterials engineering site. reports growing highly Pt Mn single layers fully activates loaded results in electrocatalytic conversion

Abstract The manufacture of nitric acid (HNO 3 ) consumes large amounts energy and causes serious environmental pollution. Electrochemical synthesis is regarded as a key way to eliminate carbon emissions from the chemicals industry. selective electrosynthesis HNO nitrogen was achieved by controllable assembly cobalt metal on graphdiyne surface using powerful tool electrochemistry at ambient conditions. As an advanced material, (GDY) has conjugated structure its rich in sp‐C triple bond skeleton, which can achieve strong interaction with atoms, resulting incomplete charge transfer between atoms. experimental theoretical calculation results show that highly oxidized (HOCo/GDY) selectively efficiently activate convert into intermediate *NO, promotes efficient overall conversion performance acid. Thus, highest yield (192.0 μg h −1 mg Faradaic efficiency (21.5 %) were low potentials.

Abstract Artificial heterostructures with structural advancements and customizable electronic interfaces are fundamental for achieving high‐performance lithium‐ion batteries (LIBs). Here, a design idea covalently bonded lateral/vertical black phosphorus (BP)‐graphdiyne oxide (GDYO) heterostructure achieved through facile ball‐milling approach, is designed. Lateral heterogeneity realized by the sp 2 ‐hybridized mode P‐C bonds, which connect atoms at edges of BP carbon terminal acetylene in GDYO. The vertical connection heterojunction GDYO connected P‐O‐C bond. Experimental theoretical studies demonstrate that BP‐GDYO incorporates interfacial engineering features, including built‐in electric fields, chemical bond interactions, maximized nanospace confinement effects. Therefore, exhibits improved electrochemical kinetics enhanced stability. Moreover, ex‐ in‐situ studies, lithiation mechanism BP‐GDYO, highlighting introduction inhibits shuttle/dissolution effect intermediates, hinders volume expansion, provides more reactive sites, ultimately promotes reversible lithium storage, clarified. anode storage performance high‐rate capacity long‐cycle stability (602.6 mAh g −1 after 1 000 cycles 2.0 A ). proposed universal represents conceptual advance building LIBs electrode.
