Recent advances in bismuthyl carbonate photocatalysts

Photocatalytic technology is a kind of green technology,which can convert solar energy into chemical energy.Photocatalytic technology is the most promising ways for solving pollution control and energy production.Bi₂O₂CO₃ photocatalyst has attracted increasing attention due to its excellent photocatalytic activity.However,BBi₂O₂CO₃ only absorbs UV light and has difficulty recycling,which restricts its practical application under solar light.The photocatalytic activity ofBi₂O₂CO₃ can be effectively improved by morphology control and modification ofBi₂O₂CO₃.The research status of zero-dimensional,one-dimensional,two-dimensional and three-dimensional structures ofBi₂O₂CO₃ photocatalyst was introduced,and it was pointed out thatBi₂O₂CO₃ with three-dimensional structure exhibited the best photocatalytic activity.The progress in the modification methods ofBi₂O₂CO₃ by doping,metal deposition and the construction of the heterojunction was reviewed.Finally,the further development ofBi₂O₂CO₃ photocatalyst in the degradation mechanism,degradation objects and degradation environment and so on should be made.
