Modulation of ultrathin nanosheet structure and nitrogen defects in graphitic carbon nitride for efficient photocatalytic bacterial inactivation

ABSTRACT: Highlights • Nitrogen-defective porous ultrathin g-C3N4 nanosheets (DUCN) were prepared.• DUCN exhibited high photocatalytic inactivation performance toward E. coli and B. subtilis.• Ultrathin nanosheets structure enhanced the interaction between photocatalysts and bacteria.• Nitrogen defects reduced charge recombination and improved H2O2 generation.• Good stability in consecutive photocatalytic inactivation experiments. The efficient generation and utilization of ROSs is a key step in determining the achievement of safe drinking water by photocatalytic bacterial inactivation technology. Although graphitic carbon nitride (g-C3N4) serves as a green and promising photocatalyst for water disinfection, insufficient bacterial capturing capacity and serious charge recombination of pristine g-C3N
