| 英文摘要 | Graphene quantum dots (GQDs) have been employed to enhance the photocatalytic performance of carbon nitride (C3N4), leveraging their superior physicochemical characteristics. The photovoltaic attributes of GQDs, influenced by their particle sizes and surface states, are contingent upon their synthesis methods. This research focused on the synthesis of GQDs with diverse particle sizes and surface features by modifying carbon nanotubes (CNTs) using HNO3. The findings indicate that prolonging the reaction time decreases the size of GQD particles and augments the presence of surface functional groups. Upon forming heterojunctions with C3N4, the GQDs-96/ H-C3N4 composite showcased superior photocatalytic degradation performance towards tetracycline hydrochloride (TC) and methyl orange (MO). This enhancement is attributed to the improved dispersibility and oxygen-containing functional groups of GQDs-96, facilitating effective interaction with H-C3N4. This research provides a new guideline and idea for regulating the particle size and surface state of GQDs for their application in enhancing the photocatalytic performance of C3N4 for the degradation of water pollutants. |
