Jahn–Teller Distortion of MnO 6 Octahedra Enhances Piezoelectric Polarization and Lattice Oxygen Activation of BaTiO 3 for Efficient Piezo‐PEC Water Splitting

Piezo‐photoelectrochemical (Piezo‐PEC) water splitting enables efficient solar conversion, yet its practical implementation is limited by an insufficient piezoelectric polarization field and sluggish water‐splitting kinetics. Herein, we firstly propose a Jahn–Teller effect‐driven strategy to regulate the local B‐si...

Defect Polarization-Metal Anchoring Coupling Enables Ni2+/Ti3+ Dual Active Sites and TiO6 Octahedral Distortion for Efficient Piezo-PEC Water Splitting of BaTiO3.

Efficient piezo-photoelectrochemical (Piezo-PEC) water splitting is critical for sustainable hydrogen production, yet its performance is largely constrained by sluggish charge separation and inefficient mechanical-to-electrical energy conversion. Here, we introduce a defect polarization-metal anchoring strategy by sele...
