Selective Catalyst Surface Access through Atomic Layer Deposition.

Article Synopsis
- Catalyst poisoning significantly shortens the lifespan of catalysts and raises costs, particularly affecting electrocatalysts used in green energy technologies like fuel cells and flow batteries.
- Current protective solutions for electrocatalysts are not very effective, as they don’t selectively target harmful species without impeding necessary reactions.
- This article discusses a method using atomic layer deposition (ALD) to apply a vanadium oxide (VO) coating on a platinum catalyst, enhancing hydrogen transport, increasing mass activity in alkaline conditions, and successfully protecting the catalyst from rapid dissolution in harsh electrolyte environments.
