| 摘 要： | Single-atom catalysts have high catalytic activity due to their unique quantum size effects and optimal atom utilization. Herein, visiblelight-responsive photocatalysts were designed by coupling Cd S with graphene quantum dots（GQDs） and platinum single atoms（Pt SAs）. GQDs and Pt SAs were successively loaded on ultrathin Cd S nanosheets through freeze-drying and in-situ photocatalytic reduction. The synergistic effect between Pt SAs and GQDs results in superior photocatalytic activity with a hydr...
