Constructing CuCo2S4/PDIsm heterojunction with synergistic dual-metal activation H2O2 boosts Fenton-like degradation of p-nitrophenol under visible light

Puntos clave

• The study shows significant enhancement in the degradation of p-nitrophenol under visible light conditions.
• Catalytic efficiency improved notably with the application of CuCo2S4 and PDIsm heterojunction, achieving over 90% degradation in specific conditions.
• Assessment using the dual-metal activation revealed synergistic effects that optimize the Fenton-like reactions for pollution treatment.
• Implications suggest a promising approach for water purification, though results may require validation in larger-scale applications.
