In situ study of the evolution of NiFe nanocatalysts in reductive and oxidative environments upon thermal treatments
Faraday Discussions(2023)
摘要
XAS monitoring of the reduction of partially oxidized NiFe nanoparticles evidenced an internal redox phenomenon induced by a residual Ni core, before complete reduction occurred with a change in the chemical structure from core–shell to alloy.
