Synthesis of TiO2/g-C3N4 nanocomposites with phosphate-oxygen functional bridges for improved photocatalytic activity

The introduced phosphate groups tightly contact TiO2 and g-C3N4 like a P-O bridge, which is helpful for the effective transfer of photogenerated electrons from g-C3N4 to TiO2, thereby the lifetime and separation of photogenerated charges are further improved, consequently leading to the enhanced photocatalytic activities for TiO2/g-C3N4 nanocomposites.
