“…Fendler and co-workers [246][247][248][249][250] have shown that it is possible to fix the cadmium sulfide colloid particles onto the membranes of surfactant vesicles and have investigated the photochemical and photocatalytic reactions of the fixed CdS in the presence of various electron donors and acceptors. Note, that there is no vectorial transmembrane PET in these systems.…”

“…[8][9][10] Synthesis of nanoparticle/ clay composites is very important in the fabrication of such different tools as optical devices, adsorbents, catalysts, sensors, polarizers, color filters, magnetic data storage media, and many others. [11][12][13][14][15][16][17][18] The main characteristics of these nanocomposites are the size and shape of the incorporated metal nanoparticles, as well as the chemical and physical properties of the clay source (ie, ion absorption capacity, active surface area, and interlamellar space). Different techniques can be used to achieve metal/clay nanocomposites, ie, distribution of nanoparticles from chemically produced metal nanoparticles in the clay matrix and by synthesis of metal nanoparticles outside and inside the clay matrix using physical methods.…”

Abstract:In this study, silver nanoparticles (Ag-NPs) were synthesized using the wet chemical reduction method on the external surface layer of talc mineral as a solid support. Silver nitrate and sodium borohydride were used as the silver precursor and reducing agent in talc. The talc was suspended in aqueous AgNO 3 solution. After the absorption of Ag + on the surface, the ions were reduced with NaBH 4 . The interlamellar space limits were without many changes (d s = 9.34-9.19 A º ); therefore, Ag-NPs formed on the exterior surface of talc, with d ave = 7.60-13.11 nm in diameter. The properties of Ag/talc nanocomposites (Ag/talc-NCs) and the diameters of the Ag-NPs prepared in this way depended on the primary AgNO 3 concentration. The prepared Ag-NPs were characterized by ultraviolet-visible spectroscopy, powder X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and Fourier transform infrared. These Ag/talc-NCs may have potential applications in the chemical and biological industries.

The study of mineral formation in biological systems, biomineralisation, provides inspiration for novel approaches to the synthesis of new materials. Biomineralisation relies on extensive organic-inorganic interactions to induce and control the synthesis of inorganic solids. Living systems exploit these interactions and utilise organised organic scaffolds to direct the precise patterning of inorganic materials over a wide range of length scales. Fundamental studies of biomineral and model systems have revealed some of the key interactions which take place at the organic-inorganic interface. This has led to extensive use of the principles at work in biomineralisation for the creation of novel materials. A biomimetic approach to materials synthesis affords control over the size, morphology and polymorph of the mineral under mild synthetic conditions.In this review, we present examples of organic-inorganic systems of different kinds, employed for the synthesis of inorganic structures with a controlled size and morphology, such as individual semiconductor and metal nanoparticles with a narrow size distribution, ordered assemblies of the nanoparticles, and materials possessing complex architectures resembling biominerals. Different synthetic strategies employing organic substances of various kinds to control crystal nucleation and growth and/or particle assembly into structures organised at a larger scale are reviewed. Topics covered include synthesis of solid nanoparticles in micelles, vesicles, protein shells, organisation of nanocrystals using biomolecular recognition, synthesis of nanoparticle arrays using ordered organic templates.
