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.

Titanium dioxide is a photocatalytically active substance used as a white pigment for cosmetics. In sunlight, titanium dioxide catalyzes decomposition of a certain amount of sebum on the skin by ultraviolet radiation. Herein, a novel white pigment for use in cosmetics was developed from titanium dioxide and phosphoric acid at pH = 4 with and without glycerin, sodium lactate, lactic acid, and urea. The chemical composition, powder properties, photocatalytic activity, color phase, and smoothness of the samples were studied. Addition of glycerin led to a decline in the intensity of the X-ray diffraction (XRD) peak of TiO 2 relative to that of the other samples. The particle size of the materials prepared with and without additives was 0.3 μm; however, extensive aggregation was observed in the obtained materials. The photocatalytic activity of TiO 2 was inhibited by phosphoric acid treatment. The materials prepared with sodium lactate, lactic acid, and glycerin exhibited higher photocatalytic activity than that prepared without additives.

Abstract:Catalytically active titanium dioxide is conventionally used as a white pigment for cosmetics, but undesirably induces a certain degree of decomposition of sebum on the skin on exposure to ultraviolet radiation in sunlight. In this work, titanium phosphates were prepared as a novel white pigment for cosmetics using titanium sulfate and phosphoric acid at various temperatures, with/without ultrasonic treatment. The chemical composition, powder properties, photocatalytic activity, color phase, moisture retention, and smoothness of the phosphates were evaluated. These titanium phosphates had less photocatalytic activity than titanium dioxide, which should be beneficial for protecting sebum on the skin. Samples prepared with ultrasonic treatment had lower visible light absorption than those not subjected to ultrasonication. The sample prepared at 40 °C with ultrasonic treatment had higher moisture retention capacity than those prepared under other conditions. Samples prepared at 40 °C had lower slipping resistance than samples prepared at 7 °C.
