Rapid Exciton Dissociation and Charge Transfer Endowed by Reinforced Interfacial Interaction in a Mixed-Dimensional 2D/3D Heterojunction Nanocatalyst for High-Efficiency Photocatalysis

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(14), P. 16725 - 16734

Published: July 16, 2024

Graphite carbon nitride (CN) has received tremendous interest, owing to its potential application in photocatalysis. However, excitonic effects stemming from Coulombic interactions limit the prospect. Herein, mixed-dimensional metal-free two-dimensional/three-dimensional (2D/3D) heterojunction composites combining 2D covalent-organic framework (COF) nanosheets and 3D hollow porous tubular CN with a phosphate group (CNP) were fabricated target regulation of exciton dissociation. Experimental characterization investigations revealed that presence could reinforce interfacial interaction between CNP COF adjust band structures for formation Z-scheme mechanism. Benefitted effective dissociation accelerated charge transport at 2D/3D heterostructure interface, optimal photocatalytic H2 evolution rate achieved up 3700 μmol h–1 g–1, which is much higher than CN, other CN-based photocatalysts reported previously. It also exhibited an excellent peroxymonosulfate-assisted tetracycline (TC) degradation capability, constant TC over COF/CNP5 sample reached 5.61 1.40 times as CNP. This study affords meritorious instance construct mixed-dimension photocatalyst opens insights regulation.
