An experimental study on the Co-CN/BiPO composite for efficient photocatalytic water splitting
The Co-C 3 N 4 /BiPO 4 photocatalyst is facilely synthesized for application in photocatalytic water splitting. The physical and chemical properties of Co-C 3 N 4 /BiPO 4 are studied by a wide range of characterization methods. The Co-CN/BP photocatalyst shows good photocatalytic activity for H 2 ev...
