中文摘要 本研究探討石墨碳硝化物（C3N4）在二氧化錳（MnO2）體系中增強其對羥基苯酚（HQ）的氧化聚合的反應。C3N4是一種富含氮的路易斯鹼，通過金屬氧化物和多酚之間的π−π作用作為橋樑。這些相互作用增加了反應物的親和力，導致反應速率提高了六倍，加速browning reaction，並改善了C3N4.HQ.MnO2複合物的穩定性。因此，類腐植酸（HS）迅速生成，且改善其表面形態和具較大的粒徑。C3N4促進的HQ.MnO2的電子轉移在HQ氧化中起著關鍵作用，擴大了原子間距和複合物形態。理論計算支持了實驗結果，說明C3N4.HQ.MnO2複合物具有較強的親和力和較高的結合能，複合物具有更穩定的結構和較窄的HOMO-LUMO能隙，有助於HS的形成。此外, 13C和1H NMR光譜證實了實驗和理論的一致性。
英文摘要 The utilization of graphitic carbon nitride (C3N4) to enhance the oxidative polymerization of hydroquinone (HQ) within manganese dioxide (MnO2) systems was investigated. C3N4, a Lewis base enriched with nitrogen, acted as a bridge through π−π interactions between metal oxides and polyphenols. These interactions increased the affinity of the reactants, resulting in an enhanced reaction rate of six-fold, accelerated browning, and improved complex stability of C3N4.HQ.MnO2 complex. As a result, a humic-like substance (HS) was rapidly formed with improved surface morphology and larger particle sizes. Electron transfer of HQ.MnO2 promoted by C3N4 played a crucial role in HQ oxidation, expanding atomic distance and composite morphology. Theoretical calculations supported the experimental results, indicating strong affinity and higher binding energies in the C3N4.HQ.MnO2 complex. The complex had a more stable structure with a narrower HOMO-LUMO gap, facilitating HS formation. 13C and 1H NMR spectra confirmed the experimental-theoretical agreement.
