Efficient generation of ¹O₂ by activating peroxymonosulfate on graphitic carbon nanoribbons for water remediation

This research paper explores the efficient generation of singlet oxygen (¹O₂) by activating peroxymonosulfate (PMS) on graphitic carbon nanoribbons (GCN) for water remediation. A novel synthesis method using a homogeneous Fenton-like solution polymerization technique produces GCN with a minimal amount of iron, which plays a crucial role in its catalytic activity and stability. The study investigates the influence of various parameters and reveals that ¹O₂ is the primary reactive oxygen species responsible for the degradation of organic pollutants, with a minor contribution from GCN-mediated electron transfer. The GCN/PMS system demonstrates high efficiency and good anti-interference ability, showing promise for water purification.
