Black phosphorus/graphitic carbon nitride: A metal-free photocatalyst for “green” photocatalytic bacterial inactivation under visible light

In the drive toward the ever-increasing standards for high-quality drinking water, exploring stable and efficient photocatalysts with excellent visible light (VL) harvesting ability for the photocatalytic water disinfection is still a challenging problem. However, most photocatalysts are solely metal-based or contain at least one metal-containing cocatalyst with detrimental environmental impacts. Here, we show that a novel metal-free 2D...
