Achieving Pt-coating-free anodes using double-layered catalyst layer structure for polymer electrolyte membrane water electrolysis
A double-layered Ir-based catalyst structure enables Pt-free PEMWE anodes by positioning porous rutile IrO 2 at the PTL interface, effectively mitigating TiO x -induced electron transport issues while retaining high OER activity at low PGM loading.
