Phosphorus-modified two-dimensional graphdiyne (C_nH_2n−2)/ZnCdS forms S-scheme heterojunctions for photocatalytic hydrogen production

Abstract

Graphdiyne (GDY) is a new type of carbon allotrope material with a network structure composed of sp- and sp2-hybrid carbon, and its excellent photoelectrochemical properties will have an extraordinary impact...

Functional Graphdiyne for Emerging Applications: Recent Advances and Future Challenges

“…In addition to these examples, other functional GDY nanoarchitectures, such as CuCo 2 O 4 /GDY heterostructure, [158] C 3 N 4 /GDY heterostructure, [84,148] Co 3 O 4 QD/GDY heterostructure, [61] CoS 2 NW/GDY heterostructure, [81] double Sscheme ZIF-67@GDY/CuI heterostructure, [159] S-scheme ZnCdS/GDY heterostructure, [160] GDY/CuMoO 4 /CuO heterostructure, [161] and GDY/CuI/NiO, [162] have been rationally designed to optimize the reaction overpotential, electron density, and carrier transfer capability for impressive H 2 production activity.…”

A novel graphdiyne (CnH2n−2) synthesis strategy: design and application of an organic/inorganic conjugated system for photocatalytic hydrogen production

“…3c shows the IR spectrum of GDY, and the peak at 1352 cm À1 is due to the skeletal vibration of the benzene ring in GDY. 34 The characteristic peak of carbon-carbon triple bond is generally between 2250 and 2100 cm À1 , but it shows two peaks when there are two alkyne bonds connected. The double peaks at 2238 cm À1 and 2115 cm À1 prove the existence of -CRC-CRC-in GDY.…”

Structural identification of single boron-doped graphdiynes by computational XPS and NEXAFS spectroscopy

“…Doping or modification of heteroatoms can regulate the charge distribution, increase the number of active sites, and enhance the ion storage capacity of GDY. 22 For example, heteroatom doping of carbon materials with B, 23 N, 24 O, 25 Si, 26 S 27 and P 28 can effectively enhance related performance. N-doped GDY structures can tune the electron distribution to improve performance for gas separation; 24 O-doped GDY structures achieve much better electrocatalytic character for the nitrogen reduction reaction (NRR), 25 and the addition of heteroatoms can greatly alter the properties of GDY.…”
