We indroduce a facile and effective fabrication of complex multimetallic nanostructures by means of block copolymer self-assembly. Two- and three-dimensional complex nanostructures, such as 'nanomesh', and 'double layered nanomeshes', and 'surface parallel cylinders on nanomesh', can be achieved by employing the self-assembly of perforated lamellar morphology in block copolymer thin films. Simultaneous integration of various metallic elements, including Pt, Au, and Co, into the self-assembled morphologies generates multimetal complex nanostructures with highly interconnected morphology and large surface area. The resultant metal nanostructures with large surface area, robust electrical connectivity and well-defined alloy composition demonstrate a high performance electrochemical catalysis for hydrogen evolution reaction. |
