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