Self-assembly of dendritic poly(ethylene glycol)-b-poly(styrene) block copolymer yields bicontinuous inverse cubic structure under certain environment. The structure has zero mean curvature and negative Gaussian curvature which renders its properties very unique. Such intricate structure can be transferred onto other materials by means of templated synthesis. Here, mesoporous 3D metal networks are synthesized by in-situ chemical reduction of metal ions on mesostructured cubic membranes. The lone pair electrons at the alkoxy termini allow coordination of electron-deficient metal, and subsequent conditioning with reductant allows nucleation of atomic metal. Growth of metal networks from the nuclei is controlled with the composition of reduction baths. The process is simple and convenient by eliminating the need of a working electrode for metal plating. The 3D metal network is evaluated for its electrochemical performance, and its catalytic activity in converting organic molecules. |
