Higher selectivity
WebThe selectivity of CO 2 hydrogenation can be significantly tuned by controlling the valence state of nickel using lanthanum–iron–nickel perovskites. Nickel with higher valence states weakens the binding of CO and increases the activation barrier for further CO hydrogenation, leading to a higher CO selectivity than the metallic nickel.
