Zno Nanocrystal

We report on the growth of ZnO nanocrystals having a hexagonal, prismatic shape, sized 700 nm × 600 nm, on bare indium tin oxide (ITO) substrates. The growth is induced by a low ion flux and involves a low-temperature electrodeposition technique. Further, vertically aligned periodic nanocrystal (NC) growth is engineered at predefined positions on polymer-coated ITO substrates patterned with ordered pores. The vertical alignment of ZnO NCs along the c-axis is achieved via ion-by-ion nucleation-controlled growth for patterned pores of size ≈600 nm; however, many-coupled branched NCs with hexagonal shape are formed when a patterned pore size of ≈200 nm is used. X-ray diffraction data is in agreement with the observed morphology. A mechanism is proposed to interpret the observed site-specific oriented/branched growth that is correlated to the pore size. As ordered NC arrays have the potential to generate new collective properties different from single NCs, our first demonstration of a cost effective and facile fabrication process opens up new possibilities for devices with versatile functionalities.

The paper presents the results of research on the disposal of large-tonnage composite polymer waste - wood-particle boards by the method of catalytic low-temperature pyrolysis for preparation of carbon materials. Salts and nickel were used as catalysts. The influence of temperature, mass ratio “waste: metal ions” on the yield and properties of carbonizate was investigated. It was found that when pyrolysis is carried out at a temperature of 600 °C for 30 min in the presence of catalysts, carbon materials are formed with a developed porous structure and high sorption activity with respect to the methylene blue dye and iodine. It is shown that the metals catalyzing pyrolysis are incorporated into the processes of the forming sorbent. The studies carried out on the treatment of biologically active river water showed a high bactericidal ability of the obtained samples of sorbents. The developed method of catalytic pyrolysis of waste made it possible to obtain bactericidal carbon sorbents that can be used for deep additional purification and disinfection of biologically treated wastewater.

Adsorption Desorption

The thermal desorption of benzene has been measured using a thermal analyzer. Pore size distributions of active carbons and carbon blacks have been determined on the basis of thermogravimetric curves using the Kelvin equation. Calculated distributions and total pore volumes have been compared with those derived from adsorption/desorption isotherms of nitrogen and benzene vapour.
