β-FeSe nanorods composited g-C(3)N(4) with enhanced photocatalytic efficiency

A series of β-FeSe nanorods composited g-C(3)N(4) were prepared. The structure, morphology, chemical state, photocatalytic activity, electrochemical impedance and photoluminescence of β-FeSe/g-C(3)N(4) composites were well characterized. It is found that the decolourization rate of 3 wt% β-FeSe/g-C(3)N(4) composites reaches 4.4 times than that of g-C(3)N(4). The improved photocatalytic properties could be ascribed to the reduced recombination of photogenerated electrons and holes, which is derived from the excellent ability of β-FeSe to capture and transfer electrons. This work provides an alternative co-catalyst for decolourizing organic matter.
