The formation of hierarchical, multimodal porosity materials with controlled shape and size pores is the essential challenge in science. Properties silica depend largely on different features: crystal structure, dispersity, surface composition, as well method preparation possible modification. In this paper, silicas obtained using additives are presented. A-50 A-380 aerosils wide-porous SiO2 milled at 300 rpm were used sol stage 20 °C, sol–gel followed by hydrothermal modification (HTT) 200...
Mechanochemical modification of low-dispersed SnO2 and high-dispersed SnO(OH)2 powders with specific surface area 6 198 m2 g−1 have been studied. The crystal, porous, electronic structure obtained products, as well their photocatalytic activity under visible light in the process dyes degradation has investigated. It established that powder is porous poorly crystalline. Its decreases after milling. On contrary, almost nonporous crystallized. increases but degree crystallinity reduces a result...
Wet gel and dried xerogel of precipitated tin oxy-hydroxide were subjected to mechanochemical microwave treatments (MChT MWT, respectively). The prepared samples studied using DTA-TG, XRD, FTIR, nitrogen adsorption–desorption. MChT MWT cause improvement crystal structure, removal structural OH-groups increase mesopores diameter as well form the meso-macroporous structure. As a result, drastic uranyl-ions sorption for all modified is observed. Sorption centers can be divided into three...
The titanium phosphate-synthesized sol–gel method was subjected to the mechanochemical treatment in a planetary ball mill Pulverisette 6 air or water environment hydrothermal at 873 K 1073 K. properties of such modified/treated samples were examined using XRF, XRD, TGA, static light scattering, FTIR Raman and adsorption/desorption N2 methods. xerogel leads small decrease contents sample, but structure remains amorphous. Additionally, during milling sample aggregation phosphate particles...
Mechanochemical modification of vanadium phosphates doped with Bi, Zr, Mo has been studied. Milled samples have investigated by means XRD, DTA-TG, FTIR, nitrogen adsorption, electrokinetic measurements. It was found that phase composition the does not change upon mechanochemical process. Milling in water causes formation porous materials. Modification surface results changes and adsorption properties milled samples.
