Abstract
Highly ordered mesoporous metals with three-dimensional (3D) connectivity are highly desirable for applications, for example, requiring efficient charge transport in electrodes or electrocatalytic materials.Here, I present a synthetic approach toward such materials from bottom-up type block copolymer (BCP)—metal nanoparticle (NP) co-assembly.A BCP was used as a structure-directing agent for controlling spatial arrangement of metal NPs.The intimate coupling of synthesis, in-depth electron tomographic characterization, and a recently developed field theory enables exquisite control of superstructure in highly ordered porous 3D continuous networks from single and binary mixtures of metal NPs. Quantitative analysis provided insights into short- and long-range NP-NP correlations, and local and global contributions to structural chirality in the networks. Results provide design rules for next generation mesoporous network superstructures from binary NP mixtures for potential applications in areas including catalysis and plasmonics
