This study proposes a controlled strategy to optimize the photocatalytic performance of hybrid catalysts by introducing organic components. The enhanced photocatalytic activity of P-FGDY/TiO2 compared to FGDY/TiO2 is attributed to the regulation of FGDY, which increases the efficiency of photogenerated electron and hole separation. This work provides a novel regulating pathway to optimize the photocatalytic activity of carbon-based hybrid photocatalysis material systems.
Structure engineering of hybrid materials has been proved to be an efficient method to screen out superior photocatalysis. The distribution and bonding environment of covalent linkage segments can be well regulated through structure decoration. Here, we propose a controlled strategy to optimize the photocatalytic performance of hybrid catalysts. Systematic adjusting of the performance can be achieved by introducing organic components into the carbon supporter. Under the guidance of this strategy, fluoride graphdiyne (FGDY) and phloroglucinol regulating FGDY (P-FGDY) is compounded with titanium dioxide (TiO2) under solvent thermal condition to obtain hybrid catalyst FGDY/TiO2 and P-FGDY/TiO2, respectively. Notably, the as-prepared P-FGDY/TiO2 exhibits superior enhancements towards photocatalytic degradation of rhodamine B, methylene blue, and levofloxacin under visible-light irradiation compared with FGDY/TiO2. These enhanced photocatalytic activities stem from the fact that the regulation of FGDY could further increase the photogenerated electron and hole separation efficiency of hybrid catalyst. This work provides a novel regulating pathway to optimize the photocatalytic activity of carbon-based hybrid photocatalysis material systems.
