Sustainability-driven photocatalysis: oxygen-doped g-C3N4 for organic contaminant degradation

This paper is not about microplastics. It discusses oxygen-doped graphitic carbon nitride as a photocatalyst for degrading organic contaminants in water, focusing on the material's enhanced charge carrier properties. While photocatalytic degradation could theoretically be applied to plastic pollutants, this study addresses general organic contaminant removal rather than microplastic pollution.
