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

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.
