Electron microscopic investigations on the important catalytic systems
Abstract:
Directed by the temperature-induced phase transformation in the alkane (from heptane to dodecane)–P123–water–TEOS quadru-component system, i.e., from a swollen inverse hexagonal phase (H2) to a swollen lamellar phase (Lα) and then to a swollen normal micelles phase (L1), complex silica materials, such as mesoporous nanofibres, multilamellar vesicles (MLVs) and mesocellular foams (MCFs), are constructed.
