Structural, thermal and photocatalytic properties of composite materials SiO2/TiO2/C

In the study the mechanochemical treatment procedure was used to prepare composite materials based on SiO2 with the addition of TiO2 and carbon black as a carbon matter. The investigations were carried out at the three rotational speeds 300, 500 and 700 rpm. Thermal and structural characteristics of the composites were investigated using N2 adsorption, TG/DTG/DTA, SEM and FT-IR...

Application of microwave heating in the preparation of functionalized activated carbons

A series of modified carbonaceous materials has been obtained via nitrogenation, oxidation and thermal treatment of peat-based activated carbons with the use of microwave heating. In order to obtain materials characterised by diverse functional groups content, both in terms of the type and quantity, the starting material was subjected to four different treatment: (1) oxidation...
