Higher selectivity

Web28 de ago. de 2024 · Extensive theoretical work has shown that high selectivity can be obtained by using multivalent weak interactions. Here we provide comprehensive experimental proof using DNA-coated particles. The ligand–receptor affinity is varied by changing the number of complementary bases, showing that fewer complementary … 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.
