  "abstract": "This study explores the utilization of a 0D/2D NiFe₂O₄/g-C₃N₄ heterojunction for the photocatalytic activation of peroxymonosulfate (PMS) to degrade methylene blue in wastewater. The NiFe₂O₄/g-C₃N₄ composite was synthesized from 0D NiFe₂O₄ and 2D g-C₃N₄ using wet impregnation and calcination. The NiFe₂O₄/g-C₃N₄ composite was then characterised using various spectroscopic and microscopic techniques and used for the photocatalytic degradation of methylene blue in the presence of PMS (1 mL, 0.1 M). The NiFe₂O₄/g-C₃N₄ composite showed a higher degradation efficiency of 97% compared to NiFe₂O₄ and g-C₃N₄ alone, which showed 69% and 53%, respectively, after 90 min of degradation. The concentration of PMS was optimized across 0.2 M, 0.4 M and 1.6 M, yielding degradation efficiencies of 99%, 91% and 74%, respectively; this indicates that the highest degradation performance is obtained at 0.2 M. Subsequently, the pH was also optimized, with pH 9 and 11 achieving 100% degradation efficiency. The radical quenching experiments showed that sulfate radicals (SO₄˙⁻) were the dominant reactive oxygen species (ROS) responsible for the degradation of methylene blue. The study showed that NiFe₂O₄/g-C₃N₄ has the potential to be used as a catalyst for PMS activation to degrade organic pollutants in wastewater under light irradiation.",
