Why Is Alloying a Prerequisite for Interstitial Carbon Playing a Promotional Role in Selective Acetylene Hydrogenation?
The thermodynamic−kinetic origin of why alloying is a prerequisite for interstitial carbon playing a promotional role in selective acetylene hydrogenation over Ni-based catalysts remains elusive. Moreover, catalytic mechanisms are frequently studied on pristine or bare surface models, overlooking the realistic surfac...
