Interfacial electric field in Zr-MOF-grafted carbon nitride to boost H2O2 piezo-synthesis under ambient conditions

Abstract

Harnessing interfacial electric fields offers a promising route to boost piezocatalytic efficiency. Here, we grafted Zr-MOF onto carbon nitride to construct an interfacial electric field, leading to a hydrogen peroxide production rate of 4.76 mmol g⁻¹ h⁻¹via water oxidation and the oxygen reduction reaction.
