| Abstract: | The exponential growth of population and industrialization has precipitated severe environmental pollution, coupled with energy crises. Building on this premise, developing green methodologies for aqueous pollutant degradation has emerged as a pivotal research frontier. Photocatalysis demonstrates remarkable potential for water pollution treatment due to its environmental friendliness. However, individual photocatalysts remain constrained by rapid charge recombination and narrow spectral response ranges. This limitation necessitates strategic modifications or the construction of heterostructured photocatalytic systems to enhance degradation efficiency, owing to accelerated charge carrier separation and an expanded light absorption spectrum. This study has adeptly fabricated an effective visible light-induced g-C3N4/NCQDs/FeTiO3 z-scheme heterojunction photocatalyst through a dualistic approach for the degradation of aquatic organic pollutants. The integration of g-C3N4, FeTiO3, and nitrogen-doped carbon quantum dots (NCQDs) elicits a synergistic effect, which promotes the separation of charge carriers and, as a corollary, enhances the photocatalytic performance. The photocatalytic degradation efficiency of methylene blue (MB) by g-C3N4/NCQDs/FeTiO3 reaches up to 93.01%, demonstrating a 6.5-fold increase compared to pristine FeTiO3 and a 2.8-fold improvement relative to the g-C3N4/NCQDs composite. Moreover, the investigation into the free radical trapping mechanisms has elucidated that the superoxide radical (·O2−) is the predominant reactive species accountable for the degradation of MB under the catalysis of the g-C3N4/NCQDs/FeTiO3 heterojunction.
