Macroporous Au materials prepared from colloidal crystals as templates

Current status and future developments in preparation and application of colloidal crystals

“…5,6 The monodisperse spherical colloids usually adopt face-centered cubic close (fcc) packing to form colloidal crystals with B26 vol% voids in the structure. [7][8][9] Therefore, the formed colloidal crystals can be used as templates to prepare macroporous materials. A lot of macroporous materials including inorganic, organic, metallic and ceramic have been successfully made through this technology.…”

Fabrication of superparamagnetic macroporous Fe3O4 and its derivates using colloidal crystals as templates

“…A characteristic of this method is that the macroporous materials acquired have spherical voids, which were occupied originally by the colloids [6,7]. The monodisperse micro-or submicrometer colloids (organic or inorganic) [8][9][10][11], usually adopt face-centered cubic (fcc) packing with $26% voids in volume [12][13][14], into which the guest molecules and nanoparticles are easily infiltrated through different strategies [15,16]. The templates subsequently can be removed by sintering for organic or acidic etching for inorganic templates to acquire the macroporous network, in which the spherical voids are periodic and interconnected via small interstitial channels [17,18].…”

Preparation of Sodium Alginate Porous Materials Using Colloidal Crystals as Templates

“…In the past decade, materials with order porous have attracted much attention due to the academic interest and important potential applications [1][2][3]. Now we use the organic colloidal crystal as templates so as to prepare the sodium alginate porous materials.…”
