Highly Effective Pyroelectric Catalysis for Simultaneous Tumor‐Targeted Dynamic Therapy and Gentle Photothermal Therapy by Oxygen‐Vacancy‐Rich CeO2–BaTiO3 Nanorods

Pyroelectric nanostructures can effectively generate temperature-mediated reactive oxygen species (ROS) through the pyroelectric effect, providing promise for treating hypoxic tumors; and therefore, the synergistic application of photothermal therapy (PTT) and pyroelectric dynamic therapy (PEDT) presents an intriguing approach for cancer therapy. However, this method still faces challenges in improving pyroelectric catalysis and achieving precise tumor localization. In this study, a nano-heterojunction based on CeO
