To address this, we herein constructed a high-entropy nanozyme (HEzyme) using a Prussian blue analog (PBA) as the platform. The HE mixing state induced lattice distortion and d-orbital modulation, endowing the PBA-based HEzyme with an enhanced POD-like activity and an exceptional photothermal conversion efficiency of 82.96%. This dual functionality enabled photothermal-adjuvant ROS amplification for triggering robust ICD-driven anti-tumor immunity. Simultaneously, the HEzyme reprogrammed tumor-associated macrophages from immunosuppressive M2 to antitumor M1 phenotypes, reversing TME immunosuppression. In 4T1 tumor-bearing mouse models, the HEzyme-based <em>in situ</em> nanovaccine achieved dual suppression of primary and distal tumors.

Herein, we present a layered tin halide hybrid, (C<small>₄</small>H<small>₁₂</small>N<small>₂</small>)<small>₂</small>[SnCl<small>₆</small>], in which crystallographically independent [SnCl<small>₆</small>] octahedra alternate with organic bilayers.
