Abstract
A method of forming a catalyst structure includes providing a catalyst support structure having a core and an inner carbide film on the core, depositing catalyst nanoparticles on the catalyst support structure, and forming an outer carbide film on the catalyst support structure after the step of depositing catalyst nanoparticles. The outer carbide film is preferentially formed on the catalyst support structure compared to the catalyst particles.
