“…The isotherm was close to type-II with a strong increase in nitrogen adsorbed volume at relative pressure higher than 0.85, in which the adsorption and desorption branches of the isotherm almost coincided. The similar isotherms have often been observed in the macroporous materials [40,41], indicative of an appreciable amount of macroporosity in the ␣-Fe 2 O 3 . These results along with the SEM and TEM observations well confirmed the presence of the 3DOM structures in the ␣-Fe 2 O 3 .…”

“…This framework is quite similar to those of previously reported surfactant-assisted meso-/macrostructured metal oxide materials. [30,31] Moreover, careful examination of these SEM micrographs reveals that the pore wall of the large macropores in A-CD are separated by smaller spherical pores with the size of 50-100 nm, which thereby forms a two-scaled macroporous structure (Figure 1e). It is reminiscent of the hierarchically meso-/macroporous titanium phosphates synthesized in the presence of the polyethylene oxide surfactant Brij 56, [32] which indicates that the surfactant molecules are not necessary for the formation of the macrochannels, but the addition of a small amount of β-cyclodextrin could lead to the presence of secondary small-scaled macropores.…”

Organic-inorganic hybrid materials of meso-/macroporous titanium triphosphonate materials were synthesized by using amino tri(methylene phosphonic acid) as the coupling molecule. The preparation was accomplished by a hydrothermal process in the presence or absence of small amounts of the diblock copolymer EO 30 PO 34 and β-cyclodextrin as the organic additives. The organic-additive-assisted preparation efficiently aided the enlargement of the surface areas and pore volumes of the resultant porous titanium triphosphonates and helped improve the wormhole-like mesoporosity. In addition to the large macrochannels, with a size of 500-

A great deal of progress has recently been made in the field of ordered porous materials with uniform channel dimensions that can be adjusted over a wide range of length scales. The present paper describes the state of the art and the evolution from highly ordered mesoporous silica, aluminosilicate and pure carbon materials to our very recent success in hierarchically structured meso-macroporous carbon materials, single and binary oxides and aluminosilicates. By means of selected examples, we want to shed some light on the current strategies for the conception of these sophisticated materials. The great potential applications of these new nanomaterials emerge while their real utilisation in some expected and traditional industrial processes such as catalysis, separation, electrode materials for fuel cells and biomaterials still faces some important challenges, for example, the high price, the pelletisation and the stability (thermal, hydrothermal and water resistance). Some new perspectives, which can open the concrete applications of these materials in nanotechnology, biotechnology, information technology and medical purposes, will be prospected.

Thermally stable macroporous zirconium phosphates with supermicroporous walls: a self-formation phenomenon of hierarchy

Abstract: A self-formation phenomenon leading to the hierarchically thermally stable macroporous zirconium phosphates with amorphous supermicroporous walls from the precursors of zirconium propoxide and orthophosphoric acid solution was observed.
