ALD SnO 2 protective decoration enhances the durability of a Pt based electrocatalyst

Electrospinning and atomic layer deposition (ALD) have been coupled to prepare functional hetero-structures with potential application in fuel cells. Electrocatalysts comprising platinum (Pt) nanoparticles dispersed onto electrospun carbon fibers were selectively decorated with tin dioxide (SnO 2 )...

Zusammenfassung:Electrospinning and atomic layer deposition (ALD) have been coupled to prepare functional hetero-structures with potential application in fuel cells. Electrocatalysts comprising platinum (Pt) nanoparticles dispersed onto electrospun carbon fibers were selectively decorated with tin dioxide (SnO 2 ) using ALD. The presence of SnO 2 led to a considerable enhancement of the catalyst durability during voltage cycling.
