Abstract
A Janus-type heterojunction between ordered-anatase and disordered-rutile phases was fabricated by selectively disordering the rutile phase of commercial P25-TiO<sub>2</sub>, and exhibits a ∼13-fold enhancement in photocatalytic H<sub>2</sub> production relative to untreated P25-TiO<sub>2</sub>.
