Nanoscale Core–Shell Catalysts for H₂Production by Methane Decomposition: Supported Nickel Nanoparticles Ensheathed in Metal Oxides

Catalytic methane decomposition provides a potentially viable route to low-cost, COx-free H2from this abundant source. A remaining challenge is to facilitate the needed low-temperature C–H bond activation with high catalytic activity and stability. We now report the design and synthesis of supported
