Construction of Multi-Defective ZnMn2O4/Carbon Nitride Three-Dimensional System for Highly Efficient Photocatalytic Sulfamethoxazole Degradation

Rational design of composite nanostructured photocatalytic systems with good sunlight absorption capacity and efficient charge separation transfer ability is an urgent problem to be solved in photocatalysis research. Here, a ZnMn2O4 decorated three-dimensional carbon nitride O, C co-doping, nitrogen defect system was prepared using simple hydrothermal method subsequent calcination method. For the reactions, presence heterostructures, C, O defects greatly promotes charges at semiconductor/semiconductor interface under local electric field, thereby extending its service life. The degradation efficiency sulfamethoxazole water as high 94.3% synergistic effects, which also suitable for complex environment. In addition, synthesized photocatalyst has chemical stability recyclability. This study provides new opportunity solve environmental pollution.
