Abstract Traditional tumour‐dynamic therapy still inevitably faces the critical challenge of limited reactive oxygen species (ROS)‐generating efficiency due to tumour hypoxia, extreme pH condition for Fenton reaction, and unsustainable mono‐catalytic reaction. To fight against these issues, we skilfully develop a tumour‐microenvironment‐driven yolk‐shell nanoreactor realize high‐efficiency persistent dynamic via cascade‐responsive dual cycling amplification •SO 4 − /•OH radicals. The with an ultrahigh payload free radical initiator is designed by encapsulating Na 2 S O 8 nanocrystals into hollow tetra‐sulphide‐introduced mesoporous silica (HTSMS) afterward enclosed epigallocatechin gallate (EG)‐Fe(II) cross‐linking. Within microenvironment, intracellular glutathione (GSH) can trigger tetra‐sulphide cleavage nanoreactors explosively release + /S /Fe 2+ EG. Then sequence cascade reactions will be activated efficiently generate (Fe ‐catalyzed oxidation), proton (•SO H decomposition), •OH (proton‐intensified oxidation). Synchronously, oxidation‐generated Fe 3+ in turn recovered excessive EG circularly amplify also disrupt osmolarity homeostasis overload weaken ROS‐scavenging systems GSH exhaustion further oxidative stress.
