چکیده

Although mesoporous metals have been synthesized by electrochemical methods, the possible compositions have been limited to noble metals (e.g., palladium, platinum, gold) and their alloys. Herein we describe the first fabrication of continuously mesoporous Cu films using polymeric micelles as soft templates to control the growth of Cu under sophisticated electrochemical conditions. Uniformly sized mesopores are evenly distributed over the entire film, and the pore walls are composed of highly crystalized Cu.

Electrochemical synthesis of mesoporous gold films toward mesospace-stimulated optical properties

Mesoporous gold (Au) films with tunable pores are expected to provide fascinating optical properties stimulated by the mesospaces, but they have not been realized yet because of the difficulty of controlling the Au crystal growth. Here, we report a reliable soft-templating method to fabricate mesoporous Au films using stable micelles of diblock copolymers, with electrochemical deposition advant...

Chiral nematic mesoporous carbon derived from nanocrystalline cellulose.

Template synthesis based on the self-assembly of lyotropic liquid crystals offers access to mesoporous solids with high specific surface areas and periodic structures. Incorporating mesopores (i.e., pores ranging from 2 to 50 nm in diameter) into carbonaceous materials may be advantageous for certain applications, including the adsorption of large molecules, electrochemical double-layer capacit...

Hierarchical Phenolic Resin-based Carbons with High Surface Area and Pore Volume Obtained by Soft-templating and Activation

Introduction Advanced applications often require carbons with high surface area and hierarchical porous structures. In response to this demand some efforts have been undertaken to create materials, which effectively combine the properties of both activated carbons (high surface area) and ordered mesoporous carbons (tunable and well-developed porosity). While there are activation methods, which ...

Soft-templating synthesis of mesoporous magnetic CuFe2O4 thin films with ordered 3D honeycomb structure and partially inverted nanocrystalline spinel domains.

Combining sol-gel chemistry with polymer templating strategies enables production of CuFe(2)O(4) thin films with both an ordered cubic network of 17 nm diameter pores and tunable spinel domain sizes. These nanocrystalline materials contain only minor structural defects with λ = 0.85 ± 0.02 and exhibit multiple functionalities, including superparamagnetic behavior (T(B)≈ 310 K) and redox- and ph...
