Highly Active And Stable Copper Catalysts Derived From Copper Silicate Double-Shell Nanofibers With Strong Metal-Support Interactions For The Rwgs Reaction

Highly active and stable copper catalysts were successfully achieved by in situ self-reduction treatment of hierarchical double-shell copper silicate hollow nanofibers. The coexistence of Cu-0 and Cu+ species in the as-prepared catalysts demonstrated the strong metal-support interactions and endowed them with outstanding catalytic performance for the RWGS reaction.
