Abstract
Herein, g-C(3)N(4)/CdS hybrids with controllable CdS nanoparticles anchoring on g-C(3)N(4) nanosheets were constructed. The effects of CdS nanoparticles on photocatalytic H(2) production and organic molecule degradation for g-C(3)N(4)/CdS hybrids were investigated. The maximum rate of H(2) production for g-C(3)N(4)/CdS sample was 1,070.9 μmol g(-1) h(-1), which was about four times higher than that of the individual g-C(3)N(4) 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.
