摘要: Visible-light sensitive photocatalysts are desirable for indoor environmental remediation applications. Photocatalysts used applications must have efficient visible-light activity and sustainable function under dark conditions, as light instruments typically switched off during the night. Herein, we report synthesis optimization of a highly Cu(II)–TiO2 nanocomposite with sustained anti-viral conditions. The synthesized exhibited superior volatile organic compound decomposition irradiation. Its quantum efficiency gaseous 2-propanol reached 68.7%. In addition, completely inactivated bacteriophage within 30 min Notably, photocatalyst also conditions after irradiation treatment. Taken together, these findings indicate that prepared is potentially an effective risk-reduction material
