Molecularly Tunable Donor–Acceptor Integrated Carbon Nitride for Sunlight‐Driven H₂O₂ Synthesis: Mechanism and Performance Insights

Small, Journal Year: 2025, Volume and Issue: unknown

Published: March 16, 2025

Abstract Graphite phase carbon nitride (CN) emerges as a promising catalyst for sunlight‐driven H 2 O synthesis owing to its merits of stable physicochemical properties, distinctive electronic structure, adjustable bandgap, etc., yet poor charge behavior, especially high carrier recombination and low migration rate, limit photocatalytic activity. Herein, molecularly tunable donor‐acceptor (D‐A) integrated CN is fabricated via cytosine doping combined with molten salt‐assisted calcination. The utilized achieves the highest H₂O₂ yield 8.07 mmol g −1 h , which exceeds initial by factor 40.4, surpassing numerous reported CN‐based photocatalysts. Series characterizations/tests (e.g., transient absorption, steady‐state SPV spectra, KPFM) theoretical calculations HOMO/LUMO, adsorption energy) confirm that incorporation K + ‐C≡N pyrimidine ring disrupts symmetry establishes D‐A significantly augmenting separation photogenerated charges. capture experiment rotating disk electrode test affirm two‐step single electron oxygen reduction pathway occurs in process synthesis.
