Research Aim: This research will look into the formation of a heterojunction structure of BiOBrxI1-x/BiOBr into a photocatalyst. This photocatalyst will have the ability to degrade some organic pollutants and oilfield wastes in an ideal and efficient manner to reduce pollution and release air pollutants. This will further provoke the idea of enhanced molecular oxygen activation capacity of bismuth oxyhalide photocatalysts for the same reason.
