“…The porous hierarchy could be further tuned by using the poly(ethylene oxide) surfactant technique [ 79 ]. Based on the principles of microbial fermentation, cytoarchitectonics and biomineralization, He and coworkers developed a novel synthetic method by which the multilayered nanostructure of yeast cell tissues can be copied by phosphates [ 80 ]. Mesoporous TiP with unique lamellar structures and mesopores on the surfaces can be synthesized ( Figure 4 i).…”

“…Mesoporous TiP with unique lamellar structures and mesopores on the surfaces can be synthesized ( Figure 4 i). Other hierarchically mesoporous phosphate nanocomposites, such as Ca-, Zn- and Mg-phosphates, can also be prepared using similar method [ 80 ]. These synthesized nanocomposites might have potential applications in the biomedical field, such as drug-release carriers, immobilized enzyme and gene and/or cell carriers.…”

Considerable efforts have been devoted to extending the range of the elemental composition of mesoporous materials since the pioneering work of the M41S family of ordered mesoporous silica by Mobil researchers. The synthesis of transition metal-containing mesostructured materials with large surface area and high porosity has drawn great attention for its potential applications in acid and redox catalysis, photocatalysis, proton conducting devices, environmental restoration and so on. Thus, various transition metals-containing mesoporous materials, including transition metal-substituted mesoporous silicates, mesostructured transition metal oxides and transition metal phosphates (TMP), have been documented in the literature. Among these, mesostructured TMP materials are less studied, but possess some unique features, partly because of the easy and facile functionalization of PO4 and/or P–OH groups, rendering them interesting functional materials. This review first introduced the general synthesis strategies for manufacturing mesostructured TMP materials, as well as advantages and disadvantages of the respective method; then, we surveyed the ongoing developments of fabrication and application of the TMP materials in three groups on the basis of their components and application fields. Future perspectives on existing problems related to the present synthesis routes and further modifying of the functional groups for the purpose of tailoring special physical-chemical properties to meet wide application requirements were also provided in the last part.

“…19 In addition, other mesoporous materials, e.g., hollow cuprous oxide microspheres, mesoporous zirconium phosphate, mesoporous zinc phosphate nanoparticles and mesoporous hydroxyapatite, have been synthesized using Baker's yeast as a biotemplate. [20][21][22][23][24][25] However, to the best of our knowledge, the synthesis of mesoporous Li 3 V 2 (PO 4 ) 3 nanocomposite microspheres using yeast as a biotemplate and their electrochemical application for high-power lithium-ion batteries have not been reported.…”

Mesoporous Li 3 V 2 (PO 4 ) 3 -carbon (LVP-C) microspheres are synthesized using Baker's yeast cells as both mesoporous structure templates and amorphous carbon sources. We find that the vanadium cations are combined with the negatively charged hydrophilic groups and are self-assembled both on the yeast cell wall surface and inside the cell by electrostatic interaction and metabolism regulation, respectively. The self-assembly leads to the formation of LVP-C microspheres with diameters of 1-8 mm. These microspheres are composed of densely aggregated nanoparticles (20-40 nm) as well as interconnected nanopores (2-15 nm), and hence they are of mesoporous nature. The nanoparticles can be easily brought into contact with electrolyte, and the open mesoporous structure allows lithium ions to easily penetrate into the microspheres. The carbon network (16.4 wt.%) on the surface of the Li 3 V 2 (PO 4 ) 3 nanoparticles facilitates electron diffusion. The mesoporous LVP-C microspheres have a high discharge capacity (about 126.7 mAh g À1 ), only 2% capacity loss of the initial value at the 50th cycle at a current density of 0.2 C, and a high rate capacity of 100.5 mAh g À1 at 5 C in the region of 3.0-4.3 V. The apparent Li + diffusion coefficient is found to be 6.76 Â 10 À10 cm 2 s À1 . The microspheres could be an ideal cathode-active material that fulfills the requirements of rechargeable lithium batteries for high power applications.

“…Generally, the formation of the specific morphology and porosity could be achieved by the application of a templating system which would be removed during heating. The template could be organic, using Pluronic P123, Pluronic F127 [ 18 ], casein [ 19 , 20 ], or yeast cells [ 20 ], or inorganic, using CaCO 3 [ 21 ], for example. Another way is linked with the application of organic compounds as synthesis modifiers.…”

Mesoporous hydroxyapatite (HA) materials demonstrate advantages as catalysts and as support systems for catalysis, as adsorbent materials for removing contamination from soil and water, and as nanocarriers of functional agents for bone-related therapies. The present research demonstrates the possibility of the enlargement of the Brunauer–Emmett–Teller specific surface area (SSA), pore volume, and average pore diameter via changing the synthesis medium and ripening the material in the mother solution after the precipitation processes have been completed. HA powders were investigated via chemical analysis, X-ray diffraction analysis, Fourier-transform IR spectroscopy, transmission electron microscopy (TEM), and scanning (SEM) electron microscopy. Their SSA, pore volume, and pore-size distributions were determined via low-temperature nitrogen adsorption measurements, the zeta potential was established, and electron paramagnetic resonance (EPR) spectroscopy was performed. When the materials were synthesized in water–ethanol and water–acetone media, the SSA and total pore volume were 52.1 m2g−1 and 116.4 m2g−1, and 0.231 and 0.286 cm3g−1, respectively. After ripening for 21 days, the particle morphology changed, the length/width aspect ratio decreased, and looser and smaller powder agglomerates were obtained. These changes in their characteristics led to an increase in SSA for the water and water–ethanol samples, while pore volume demonstrated a multiplied increase for all samples, reaching 0.593 cm3g−1 for the water–acetone sample.
