The high density of states (DOS) clustered around the Fermi level in both nickel and cobalt Schiff base complexes (Figure a&b) profoundly impacts their electrical and catalytic properties by dictating the availability of electronic states for charge transfer and reaction intermediates. In electronic terms, a dense DOS near the Fermi level implies a significant number of accessible energy states, enhancing the complexes' electrical conductivity by facilitating efficient electron mobility. This property is particularly advantageous in electrocatalysis, as it allows for rapid electron exchange between the catalyst and reactants, thereby improving charge-transfer kinetics.
