Title: Enhanced photocatalytic performance of g-C{sub 3}N{sub 4} with BiOCl quantum dots modification

Highlights: • Novel BiOCl quantum dots modified g-C{sub 3}N{sub 4} photocatalyst was synthesized. • BiOCl-g-C{sub 3}N{sub 4} showed much higher photocatalytic activity than pure g-C{sub 3}N{sub 4} and BiOCl. • High separation efficiency of photoinduced carriers results in the enhanced performance. - Abstract: Novel BiOCl quantum dots modified g-C{sub 3}N{sub 4} photocatalyst was synthesized by a one-step chemical bath method at low temperature. The photocatalyst was characterized using X-ray diffraction, high-resolution transmission microscopy UV–visible light diffusion reflectance spectrometry, and photoluminescence spectroscopy. The results indicated that BiOCl quantum dots were dispersed on g-C{sub 3}N{sub 4} to form heterojunction structures with high specific surface area. BiOCl-g-C{sub 3}N{sub 4} showed much higher photocatalytic activity than pure g-C{sub 3}N{sub 4} and BiOCl for rhodamine B degradation. The enhanced performance was induced by the high separation efficiency of photoinduced carriers.
