The material systems like La-doped NaTaO3 are not useful in the solar spectrum.
Thus, anion and cation doping can adjust the band structure of semiconductors, and it can also have an impact on the particle size and surface structure of materials [13], which usually results in a better photocatalytic activity [14].
