In situ synthesis of α-β phase heterojunction on Bi2O3 nanowires with exceptional visible-light photocatalytic performance

When Alpha met Beta: A tunable α-β surface phase junction on Bi2O3 can significantly improve photocatalytic degradation of RhB and MO solution over individual α-Bi2O3 or β-Bi2O3 surface phases. This enhanced photocatalytic performance is mainly attributed to the efficient charge separation and transfer across the α-β phase junction.
