Heterogeneous mesoporous oxides grown in porous anodic alumina

Mesoporous Structures Confined in Anodic Alumina Membranes

“…The second approach follows the EISA process36 conventionally used in thin film synthesis. It involves soaking the alumina substrate with small amounts of precursor solutions and subsequent solvent evaporation‐induced gelation and structure formation 81–89. Synthesis solutions used for this approach contain comparatively high amounts of volatile solvent and low surfactant concentrations.…”

“…An overview over the structures and mesopore orientations within the channels of porous alumina membranes is given in Figure . Note that cubic phases were synthesized inside anodic alumina membranes,83, 84 but so far no details regarding their orientation with respect to the channel wall have been discussed.…”

“…In related work, sequential loading techniques were employed to overcome the problem of incomplete pore‐filling, resulting not only in multiple mesoporous silica phases83 but also in composites of different mesoporous oxides ( Figure ) 84. In the first case, ionic CTAC and Pluronic P123 were used as structure directing agents to obtain mesostructured composite membranes via the EISA approach.…”

Structural, optical and thermal properties of nanoporous aluminum

“…In view of their practical importance, aluminum porous materials were intensively studied in the last decades [1][2][3][4][5][6][7][8][9][10][11] due to their interesting electrical, optical and structural properties for the reason of its self organized pores that have quasi-cylindrical shape which constitute a technological revolution and find now many applications such as filtration membranes [12,13], as backing of fabrication nanowires [14][15][16], as photonic crystals [17,18], as humidity sensors [19,20], or as cathodes for organic light emitting diodes [21,22]. In the literature many attempts are reported in order to find relationships between porosity, thermal properties [23,24], optical properties [11,25,26], and this by exploring the effect of size, form and density of the pores where whose fine tuning and its filling by various types of materials gives cells for energy applications such as solar cells and heating panels.…”

Mesoporous Nanofibers from Dual Structure‐Directing Agents in AAO: Mesostructural Control and their Catalytic Applications

“…Loureiro et al demonstrated that oxide and silica mesoporous nanofibers, with a heterogeneous structure, can be obtained by step-by-step infiltration of different surfactant solutions into an AAO membrane. [10] On the other hand, no attempts were reported on the preparation of MSNFs in the pores of an AAO membrane, templated by dual structure-directing agents.…”
