A UV-Vis absorption spectra of Pd, MOF-525, Pd@MOF-525 and Pd@MOF-525@HA. B Z-scan data at different pulse energy of Pd@MOF-525 (100 µg/mL) under the excitation at 800 nm. C The relationship between ΔT₀ and E on a log-log scale excited by 800 nm laser. D ¹O₂ generation under different conditions detected by ABDA (Pd@MOF-525@HA:100 µg/mL, H₂O₂:100 µM). E Time-dependent generation of ¹O₂ (treated with different conditions) detected by ABDA. F The O₂ concentration of solution treated with Pd@MOF-525@HA upon repeating addition of H₂O₂. G Detect the production of ∙OH with DCFH-DA under dark condition. H ESR signals of Pd@MOF-525@HA trapped by DMPO. I ESR signals of Pd@MOF-525@HA trapped by TEMP
