- Abstract
- In this research, we synthesized a novel panchromatic absorption dimer porphyrin and designed a dimer molecule with maximum absorption in the visible and NIR regions. The work was followed and mon-itored by its photocatalytic function with anatase TiO2 and brookite-rutile TiO2, and preliminarily com-pared and tested its photocatalytic disinfection of gram-negative bacteria Escherichia coli (E. coli ) in visible light conditions toward the potential of future studies. The finding results were compared with the bare anatase TiO2 and brookite-rutile TiO2. The prepared structure of molecules was confirmed by SEM, EDS, XRD, XPS, and solid-state diffuse reflectance spectral studies. (C) 2021 Elsevier B.V. All rights reserved.
