BiOBr/BiOI photocatalyst with different molar ratios was synthesized via a simple one-step solvothermal method. The uniform flower-like BiOBr/BiOI (3 : 1) owns high photocatalytic degradation efficiency, excellent recyclability and stability.
A novel nonstoichiometric inter-bismuth oxyiodides heterostructure photocatalyst are synthesized and exhibited high potential for applications in visible-light photocatalytic environmental cleaning.
