Fabrication of g-C3N4 Nanosheets Anchored With Controllable CdS Nanoparticles for Enhanced Visible-Light Photocatalytic Performance

Herein, g-C3N4/CdS hybrids with controllable CdS nanoparticles anchoring on g-C3N4 nanosheets were constructed. The effects of CdS nanoparticles on photocatalytic H-2 production and organic molecule degradation for g-C3N4/CdS hybrids were investigated. The maximum rate of H-2 production for g-C3N4/CdS sample was 1,070.9 mu mol g(-1) h(-1), which was about four times higher than that of the individual g-C3N4 nanosheet sample. The enhanced photocatalytic performance for prepared hybrids could be mainly attributed to the following causes: the formed heterojunctions can contribute to the light absorption and separation of photogenerated electrons and holes, the two-dimensional layered structure facilitates the transmission and transfer of electrons, and high specific surface area could provide more exposed active sites.

Automated summary

The g-C3N4/CdS hybrids with controllable CdS nanoparticles anchoring on g-C3N4 nanosheets were constructed, showing enhanced photocatalytic performance for hydrogen production and organic molecule degradation. The improved performance can be mainly attributed to the formed heterojunctions, two-dimensional layered structure, and high specific surface area.
