| description | Improving spectral utilization and carrier separation efficiency is a key point in photocatalysis research. Herein, we prepare hollow g-C<sub>3</sub>N<sub>4</sub> nanospheres by the template method and synthesize a g-C<sub>3</sub>N<sub>4</sub>@Cu<sub>0.5</sub>In<sub>0.5</sub>S core-shell S-scheme photothermal nanoreactor by a simple chemical deposition method. The unique hollow core-shell structure of g-C<sub>3</sub>N<sub>4</sub>@Cu<sub>0.5</sub>In<sub>0.5</sub>S is beneficial to expand the spectral absorption range and improving photon utilization. At the same time, the photogenerated carriers can be separated, driven by the internal electric field. In addition, g-C<sub>3</sub>N<sub>4</sub>@Cu<sub>0.5</sub>In<sub>0.5</sub>S also has a significantly enhanced photothermal effect, which promotes the photocatalytic reaction by increasing the temperature of the reactor. The benefit from the synergistic effect of light and heat, the H<sub>2</sub> evolution rate of g-C<sub>3</sub>N<sub>4</sub>@Cu<sub>0.5</sub>In<sub>0.5</sub>S is as high as 2325.68 μmol h<sup>−1</sup> g<sup>−1</sup>, and the degradation efficiency of oxytetracycline under visible light is 95.7%. The strategy of combining S-scheme heterojunction with photothermal effects provides a promising insight for the development of an efficient photocatalytic reaction. |
