Pathogenic microorganisms related to infectious diseases severely threaten human health, and visible-light-driven (VLD) photocatalysis is a promising strategy for mitigating microbial-induced health crises. In this work, a superior and effective VLD photocatalyst comprising a red phosphorus nanodot-modified one-dimensional carbon nitride nanotube (RP-CN) heterostructure was synthesized with a simple chemical vapor deposition method and used for bacterial inactivation. The optimized RP (40)-CN rapidly and completely destroyed Escherichia coli and Staphylococcus aureus (10(7) CFU mL(-1)) within 25 and 30 min under irradiation with a white LED, respectively. The efficient photocatalytic activity was attributed to the fact that the matching work function in the CN-RP heterojunction promotes the charge migration/separation that occurs at the CN and RP interface and the broad absorption spectra by RP loading. Additional unpaired photoelectrons reacted with water to generate center dot O-2(-) radicals and H2O2 for efficient bacterial cell inactivation. The present study highlights the design of nanostructured photocatalysts with wide spectral responses for efficient energy conversion and wide antibacterial scope.
