Colorimetric detection of H2O2 based on the synergistic catalytic enhancement effect of Fe3O4@NH2-MIL-88B.
Hydrogen peroxide (H2O2) is often illegally used in food processing, and mainstream H2O2 colorimetric detection strategies in recent years have been plagued by drawbacks including low catalytic activity of single nanozymes, unstable chromogenic signals, and insufficient adaptability to complex food matrices.
