Efficient Photocatalytic Cleavage of Lignin Models by a Soluble Perylene Diimide/Carbon Nitride S‐Scheme Heterojunction

Angewandte Chemie, Journal Year: 2023, Volume and Issue: 135(44)

Published: Sept. 7, 2023

Abstract 3,4,9,10‐Perylenetetracarboxylic dianhydride (PDI) is one of the best n‐type organic semiconductors and an ideal light‐driven catalyst for lignin depolymerization. However, charge localization effect excessively strong intermolecular aggregation trend in PDI result rapid electron‐hole (e − −h + ) recombination, which limits photocatalytic performance. Herein, polymeric carbon nitride/polyhedral oligomeric silsesquioxane (p‐CN/P‐PDI) S‐scheme heterojunction photocatalyst was prepared by solvent evaporation‐deposition method C−C bond selective cleavage β‐O‐4 model. Based on material characterization results, synergic role polyhedral (POSS) maintains appropriate domains, achieves better solar light utilization, faster charge‐transfer efficiency, greater redox capacity. Notably, 3 % p‐CN/P‐PDI heterostructure exhibits a remarkable enhancement conversion achieving approximately 16.42 2.57 times higher rates compared to modified (POSS‐PDI) nitride (p‐CN), respectively.
