(A) Time-dependent changes in pressure with different volume of Pt/SiO2 (1.00 mg/mL):Blank 0, (a) 3, (b) 6, (c) 9, (d) 12,(e) 15 μL in the tiny outfit containing 4 mL of 1.6 mol●L−1 H2O2. (B): the linear relationship between pressure signal and the volume of Pt/SiO2 at different reaction time, 15 min (a) and 30 min (b).
