Harvesting mechanical energy induces piezoelectric polarization of MIL-100(Fe) for cocatalyst-free hydrogen production

Abstract

To suit the urgency of a new strategy for hydrogen (H₂) evolution, a metal–organic framework (MIL-100(Fe)) is applied in the piezoelectric-driven process for catalytic H₂ generation. Herein, the piezoelectric property of MIL-100(Fe) was firstly reported and the material exhibited a high yield of H₂ (2.80 mmol g⁻¹ h⁻¹) under mechanical vibration without cocatalysts.
