a Time profiles of H2O2 evolution within 20 min in different systems. b H2O2 yield of BIO and BF1.5 in pure water/air and pure water/Ar in a sealable reactor at 20-min reaction time. c Impact of various capture reagents on H2O2 evolution by BF1.5. (1,4-triethanolamine (TEOA), tert-butanol (TBA), sodium bromates (NaBrO3) and benzoquinone (p-BQ) for piezo-holes, ·OH, piezo-electrons and ·O2− capture, respectively). d Mechanism of H2O2 generation over BF1.5. The error bars in (a, b, c) represent the standard deviations from two parallel measurements.
