Boron-doped TiO2 photocatalyst with a tunable anatase/rutile ratio was synthesized.
Boron-doped TiO2 with phase-junction facilitated the separation of electron-hole pairs.
Photocatalytic degradation intermediates of atrazine were identified.
Mechanism of photocatalytic atrazine degradation by boron-doped TiO2 was elucidated.
