Novel 3DOM BiVO4/TiO2 nanocomposites for highly enhanced photocatalytic activity

BiVO₄ nanoparticles in the 3DOM TiO₂ inverse opal structure act as a sensitizer to absorb visible light and to transfer efficiently high energy electrons to TiO₂ to ensure long lifetime of photogenerated charges and keep them well separated, explaining the extraordinarily high photocatalytic performance of 3DOM BiVO₄/TiO₂ nanocomposites.
