At-line monitoring of hydrogen peroxide released from its photocatalytic and continuous synthesis

Abstract

Providing hydrogen peroxide (H2O2) for enzyme-catalyzed reactions requires a careful balance between sufficient reactivity and toxicity. Herein, we demonstrate the photocatalytic synthesis of H2O2 in a continuous operation set-up using nitrogen-doped carbon nanodots (N-CNDs) and simultaneous determination of this in situ synthesis by continuous measurement with a novel developed H2O2 sensor.
