Co core/Pt partial shell alloy electrocatalysts have been developed
for electrochemical oxidation of lignin to industrial products.
It has been concluded that on these electrocatalysts, the lignin
oxidation process is quasi-reversible with intermediate heterogeneous
charge transfer rate constants. It is likely that, due to lignin'scomplex structure, the oxidation mechanism is complex, with
several charge transfer processes at different electrode potentials
and possible proceeding homogeneous chemical reactions. Several
electrochemical oxidation products have been identified, and
product concentrations have been estimated. The rates of generation
of oxidation products on a mass of catalyst basis can be
determined from this data
