Activating a Metallization Switch for Record Hydrogen Evolution in Single‐Atom Modified Polar MOF Piezocatalysts

Advanced Materials, EarlyView.
ABSTRACT Piezocatalytic hydrogen evolution enables the conversion of mechanical energy into chemical fuels, but its efficiency is constrained by a trade‐off between piezoelectric polarization and electronic conductivity. Strong piezoelectric polarization is essential for sufficient driving force, yet highly polar materials typically suffer from poor ...
