FIELD: catalysing electrochemical redox reaction.

SUBSTANCE: invention relates to a method for catalysing an electrochemical redox reaction of active particles in a conducting solution. The method includes: providing an electrocatalytic matrix containing a supporting substrate; surface structures protruding from the support substrate, the surface structures comprising an electrocatalyst; a functional surface on the electrocatalyst, wherein the functional surface is located in the upper part of the surface structures and wherein the functional surface is intended for contact with active particles in the conductive solution; immersing surface structures in the solution and introducing a counter electrode into it; and generating a current or voltage between the electrocatalyst and the counter electrode such that the charge density, voltage or current, is focused on the functional surfaces and the active particles undergo an oxidation-reduction reaction upon contact with the functional surfaces. In this case, the plurality of surface structures has a uniform size and edges and/or vertices that contain the catalyst, the catalyst is applied to the top surface of the surface structures and is a material different from the surface structure, the electrocatalyst is applied to the vertices of the surface structure, the electrocatalyst is applied to less than about 50% to approximately 0.000001% of the matrix surface when viewed from above.

EFFECT: invention provides an alternative method for catalysing an electrochemical redox reaction.
