Opis:
Currently significant amounts of wastes, which pose a real threat to the natural environment and human health, are produced worldwide. One way to get rid of waste materials is to dispose them in landfills but some of them no longer perform their function due to overfilling. For this reason, scientists pay more and more attention to the search for  their possible disposal and/or recycling, as it is impossible to prevent its generation completely. Recently, many researchers have taken up the topic of the use of agri-food wastes due to their low cost and widespread availability as a starting material for the production of activated carbons. As a result, it was found out that organic wastes are very successful precursors of organic matter and the obtained activated carbons are characterized by a very well developed porous structure. The paper presents a literature review regarding the possibility of using various waste materials under different impregnation and preparation conditions to obtain activated carbons with a developed surface area and good adsorption properties.

Opis:
In the study the mechanochemical synthesis in the planetary ball mill was used to prepare photocatalytic materials obtained on the basis of TiO2 and nickel(II) acetylacetonate as a Ni2+ source. Three materials with different contents of Ni2+: 5, 10 and 20% wt. were prepared. The obtained materials were calcinated at 800°C for 1 h. Their physicochemical properties were investigated using the N2 adsorption/desorption, FT-IR/PAS, XRD, UV-Vis/DRS and SEM methods. Additionally, thermal stability of the obtained materials was examined (TGA/DTG/DTA). Photocatalytic activity of the samples was tested in relation to the aqueous solution of Safranin T (initial concentration C0 = 1×10-5 mol L-1) at the visible light (Vis). The results indicate that the mechanochemical synthesis is an effective and simple method for preparing materials with photocatalytic properties. All obtained materials were characterized by greater photocatalytic activity compared to the initial TiO2.
