a Mechanism diagram of terephthalic acid (TA) capturing hydroxyl radicals (•OH). Spectra of samples containing phosphate buffer (0.1 M, pH 4), H2O2 (50 mM), and visible light illumination (λ ≥ 400 nm, 15 min). b The fluorescence emission spectra in the presence of Pd NSs (12.6 μg/mL) and TA (66.7 μM). c Mechanism diagram of KBrO3 capturing hot electronics. d The absorption spectrum in the presence of Pd NSs (12.6 μg/mL), KBrO3 (0.3 mg/mL), and TMB (0.7 mM)
