Magnetic catalytic nickel particles for on-demand control of electrocatalytic processes

Magnetoswitchable control of electrochemical processes has been commonly relied on ferromagnetic spheres functionalized with a reactive moiety. Here we eliminated the need for functionalizing magnetic beads by combining the electrocatalytic and magnetic properties of nickel particles. The magnetic-controlled nickel-induced redox transformations are demonstrated for the on-demand oxidation of alcohols, sugars and amino acids. This represents the first example of a magnetoswitchable-controlled electrochemistry where the magnetic and catalytic properties are combined in the same material.
