Title
Alumina coated nickel nanoparticles as a highly active catalyst for dry reforming of methane
Abstract

•Alumina coated Ni NPs were prepared employing atomic layer deposition (ALD).•Coated NPs showed impressive activity and stability as catalyst for DRM.•The alumina coating strongly inhibits catalyst sintering at high temperatures.•The stabilization against sintering is a crucial factor for the stable activity.

Alumina coated nickel nanoparticles were prepared employing atomic layer deposition (ALD) on nickel oxide (NiO) nanoparticles and subsequent reduction of the NiO core. The materials showed impressive activity and stability for dry reforming of methane at elevated temperatures (700–800 °C), especially when compared to the uncoated and reduced NiO nanoparticles. The stabilization against sintering at high temperatures is the crucial factor explaining the high catalytic activity of alumina coated Ni nanoparticles.
