Abstract:
The development of metal-free photocatalyst to make maximum use of the solar energy for photocatalytic disinfection is highly desired. Herein, boron-and phenyl-codoped graphitic carbon nitride was prepared by thermal polycondensation of cyanamide with 3-aminobenzeneboronic acid and applied as photocatalyst to inactivate Escherichia coli (E. coli). The photocatalysts exhibited the enhanced light responsive range over ultraviolet to near infrared light and 99.9% bacteria could be inactivated within 3 h with a low concentration of photocatalyst under the irradiation of simulated solar light. The disinfection mechanism was studied by scavenger experiments, indicating H2O2 was the main reactive species for the inactivation of bacteria. Finally, the photocatalyst was deposited on the surface of solid material and also exhibited strong disinfection performance. Taking advantage of excellent disinfection activity and low cytotoxicity, the photocatalyst showed a promising application in solar-driven photocatalytic disinfection in public place.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...
