In this study, CoS nanoflower as a cocatalyst was loaded onto two-dimension carbon nitride (2D CN) to enhance the photocatalytic performance for the degradation of Rhodamine B. The CoS nanoflower demonstrated the capability of extracting photogenerated electrons rapidly from 2D CN to promote efficient charge separation. The CoS/2D CN showed improved degradation activity compared to 2D CN, as well as superior photostability after four cycles, and was also effective for photocatalytic H2 evolution reaction.
Transition metal sulfides with their own capability of ultrafast electron extraction have aroused wide concerns in the field of photocatalysis research. In this work, CoS nanoflower as cocatalyst is in-situ mounted on twodimension carbon nitride (2D CN) to realize the enhanced photocatalytic performance for the degradation of rhodamine B (RhB). As demonstrated by the photoluminescence (PL) spectra and photocurrent measurement, the CoS nanoflower can work as co-catalyst to extract photogenerated electrons rapidly from 2D CN to promote efficient charge separation. As expected, the maximum degradation activity of CoS/2D CN displays a distinct improvement compared with that of 2D CN. Meanwhile, the CoS/2D CN displays a superior photostability after four cycles. Moreover, the CoS/2D CN can also be used for photocatalytic H2 evolution reaction.
