Salt‐Acid‐Surfactant Lyotropic Liquid Crystalline Mesophases: Synthesis of Highly Transparent Mesoporous Calcium Hydroxyapatite Thin Films

Lyotropic Liquid Crystalline Mesophases Made of Salt‐Acid‐Surfactant Systems for the Synthesis of Novel Mesoporous Lithium Metal Phosphates

“…The expansion of the pore‐size to 25–30 nm and crystallization of the pore‐walls were observed in all LMPs, see Figures b and S3. The line shape of the isotherms reflects these changes in the pore system as observed in mesoporous calcium hydroxyapatite, prepared using a similar method …”

“…The line shape of the isotherms reflects these changes in the pore system as observed in mesoporous calcium hydroxyapatite, prepared using a similar method. [15] The crystallization of the pore-walls has also been shown using XRD and TEM imaging techniques. Figures 6 and 7 show sets of XRD patterns, obtained from the DLMP60 of Ni(II), Mn(II), and Co(II).…”

“…There have been also many preparation methods to produce mesoporous metal oxides by hard‐ or soft‐templating approaches. However, there are few methods to synthesize metal chalcogenides, metal phosphates, and metal sulphates which are highly important for applications in energy production and storage . To fully understand and control the properties of these materials, many efforts must be undertaken.…”

“…However, there are few methods to synthesize metal chalcogenides, [13] metal phosphates, [14][15][16] and metal sulphates [17] which are highly important for applications in energy production and storage. [14][15][16][17][18][19][20][21][22] To fully understand and control the properties of these materials, many efforts must be undertaken. Recent investigations show that mesoporous materials (MMs) have many advantages in energy generation, conversion, and storage.…”

“…Here, we show that a better kinetic control over the metal phosphate formation could be achieved using phosphoric acid (PA, weak acid) as a phosphate source and by introducing lyotropic anions (such as phosphate related ions, H 2 PO 4 À , HPO 4 2À , and PO 4 3À ) for the assembly of surfactant molecules into micelles. [15,16] PA-non-ionic surfactant [39] and salt-non-ionic surfactant mesophases [40][41][42] are all important in the process and need further exploration. Here, we show that salt-PA-surfactant mesophases can be used as a media to synthesize mesoporous LMP powders in various morphologies.…”
