SnO2-coupled boron-phosphorus co-doped g-C3N4 nanocomposites have been synthesized.
Nanocomposite exhibits enhanced visible-light activities for pollutant degradation.
Produced hydroxyl radical amounts are agreeable with enhanced photocatalytic activities.
Enhanced activity depends on extended visible-light absorption after co-doping B and P.
Enhanced activity is also attributed to promoted charge separation after coupling SnO2.
