Abstract

A new p-type photocathode LaFeO₃ was successfully fabricated, and a stable (120 h) and effective water splitting (H₂: 11.5 μmol h⁻¹, O₂: 5.7 μmol h⁻¹) was realized via construction of a p-LaFeO₃/n-Fe₂O₃ photocell. This study offers a new alternative to p-type photocathode materials and the low cost design of durable PEC devices for solar conversion.
