“…[59] mine groups in EDTMP could chelate metal ions in the water, which is consistent with previously reported organosilica adsorbents. [63] The adsorption of Cu 2+ , Pb 2+ , and Cd 2+ ions by ordered mesoporous titanium phosphonates (PMTP-1, surface area: 1066 m 2 g À1 ) [48] appeared to follow a Langmuir-type behavior, with the ions being almost quantitatively adsorbed until saturation of the binding sites was reached (Figure 8 a) , and Cd 2+ , respectively, which is comparable to previous PMO adsorbents. [63,65] The PMTP-1 adsorbent possessed high distribution coefficients (K d ), particularly at low metal ion concentrations (67.44 L g À1 if treating a 2 10 À5 m Cu 2+ solution).…”

The synthesis of porous hybrid materials has been extended to mesoporous non-silica-based organic-inorganic hybrid materials, in which mesoporous metal phosphonates represent an important family. By using organically bridged polyphosphonic acids as coupling molecules, the homogeneous incorporation of a considerable number of organic functional groups into the metal phosphonate hybrid framework has been realized. Small amounts of organic additives and the pH value of the reaction solution have a large impact on the morphology and textural properties of the resultant hybrid mesoporous metal phosphonate solids. Cationic and nonionic surfactants can be used as templates for the synthesis of ordered mesoporous metal phosphonates. The materials are used as efficient adsorbents for heavy metal ions, CO₂, and aldehydes, as well as in the separation of polycyclic aromatic hydrocarbons. They are also useful photocatalysts under UV and simulated solar light irradiation for organic dye degradation. Further functionalization of the synthesized mesoporous hybrids makes them oxidation and acid catalysts, both with impressive performances in the fields of sustainable energy and environment.

During the development of multifunctional and advanced energy materials, mesoporous organic-inorganic metal phosphonate hybrids are considered as a promising candidate for environmentally friendly materials with multifunctionalities, which have attracted much attention because of the combination of superior properties from both the organic and inorganic components. They are not just physical mixtures of organic and inorganic moieties, but regarded as nanocomposites with organic and inorganic components that are intimately mixed on a molecular level. By using organically bridged polyphosphonic acids and their derivatives (i.e. salts and esters) as coupling molecules, the homogeneous incorporation of a considerable number of organic functional groups into the hybrid framework has been realized. Furthermore, the incorporation of mesoporosity with high surface area, adjustable pore size and large pore volume could contribute to the enhanced performances in various areas. This paper systematically reviewed the synthesis principle of the mesoporous metal phosphonates including the synthesis mechanism, mesophase adjustment, pore size control, morphological design and the crystallinity enhancement. The applications of these materials in the fields of adsorption, separation, catalysis, biosensing and controlled drug release were elaborated and the further development and the perspective of the mesoporous phosphonate were expected.
