Specific generation of reactive oxygen species (ROS) within tumors in situ catalyzed by nanozymes is a promising strategy for cancer therapeutics. However, it remains significant challenge to fabricate highly efficient acting the tumor microenvironment. Herein, we develop bimetallic nanozyme (Pt50Sn50) with photothermal enhancement dual enzymatic activities catalytic therapy. The structures and PtSn nanoclusters (BNCs) different Sn content are explored evaluated systematically. Experimental comparisons show that Pt50Sn50 BNCs exhibit highest among all those investigated, including activity property, due SnO2–x vacancy (Ovac) sites on surface BNCs. Specifically, photothermal-enhanced peroxidase-like catalase-like activities, as well significantly enhanced anticancer efficacy both multicellular spheroids vivo experiments. Due high X-ray attenuation coefficient excellent light absorption also dual-mode imaging capacity computed tomography photoacoustic imaging, which could achieve real-time monitoring therapeutic process. Therefore, this work will advance development noble-metal optimal composition
