Local synergetic collaboration between Pd and local tetrahedral symmetric Ni oxide enables ultra-high-performance CO 2 thermal methanation

Tetrahedral symmetric NiO 2 and Pd respectively facilitate H 2 splitting and CO 2 to CO reduction and thus enable an ultra-high CH 4 production yield performance in the epitaxial interfaces in the bimetallic NiO 2 @Pd NPs.
