Rational design of Z-scheme/Type-Ⅱ g-C3N4/TiO2/MnO2 heterojunctions with synergistic piezo-photocatalysis for efficient removal of organic pollutants

Puntos clave

• Efficient removal of organic pollutants was achieved with a heterojunction composed of g-C3N4, TiO2, and MnO2.
• The heterogeneous system shows a notable performance enhancement in synergy from piezo-photocatalysis.
• Designing the Z-scheme heterojunction allows improved charge separation, enhancing photocatalytic activity.
• The findings highlight the potential for environmental applications in wastewater treatment using advanced materials.
