One pot hydrolysis synthesis of Fe-BiOCl nanoflower photocatalysts with efficient visible light sterilization performance
Source abstract
Abstract
Visible photocatalytic sterilization as an emerging research area has great potential to mitigate biofouling problems faced by marine underwater facilities. Here, a facile strategy based on the thermodynamic simulation and DFT calculation was developed for the first time by using room-temperature hydrolysis to obtain Fe-BiOCl catalysts with three-dimensional flower-like self-assembled structures. It is indicated the addition of FeCl 3·6H 2O to the CaCl 2 aqueous solution facilitates the ionization of Fe 3+ and Bi 3+ , which could further participate in hydrolysis reactions to form Fe doped BiOCl. Fe-BiOCl shows narrowed band gap of 2.20 eV and large specific surface area of 78.94 m 2g −1 , it achieved 69.7 % degradation of MO in 120 min, and effectively inactivate sulfur-oxidizing bacteria (SOB) cultured in simulated seawater within 2 h of visible light irradiation. This work provides a green route for the industrial preparation of BiOCl catalytic materials for the protection of marine concrete equipment.
