The selectivity of CO2 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.
通过控制镧铁镍钙钛矿中镍的价态，可以显著调节 CO2 加氢的选择性。具有较高价态的镍削弱了 CO 的结合，增加了进一步 CO 加氢的活化能垒，从而使 CO 选择性高于金属镍。
