THE INVESTIGATION OF THE POROUS STRUCTURE OF CARBON SORBENTS BASED ON β-CYCLODEXTRIN FOR USE IN ENVIRONMENTAL PROTECTION TECHNOLOGIES

Autor: Ihor Bordun, Myroslav Malovanyy, Ewelina Szymczykiewicz

Publikováno v: Environmental Problems, Vol 8, Iss 2, Pp 108-116 (2023)

In this paper, the porous structure of three types of β-cyclodextrin (β-CD) carbons was synthesized and investigated. The first carbon was obtained from pure β-CD, the second carbon was synthesized from β-CD using the KOH activator, and the third

Publikováno v: Energies, Vol 17, Iss 4, p 903 (2024)

This article presents the technology for the preparation of a nitrogen-containing nanoporous bio-carbon and investigates its properties. It has been shown that the synthesised bio-carbon is characterised by a high degree of homogeneity, which has bee

Synthesis and Electrochemical Properties of Fe3O4/C Nanocomposites for Symmetric Supercapacitors

Autor: Ihor Bordun, Ewelina Szymczykiewicz

Publikováno v: Applied Sciences, Vol 14, Iss 2, p 677 (2024)

In the work, nanostructured Fe3O4/C composites based on natural raw materials (beet pulp and corn stalks) are synthesised in various ways. Iron chloride FeCl3 is used as an activator. The synthesised composites are investigated using the following me
