Abstract

The chemical composition of Karatau phosphorite raw materials and of solid waste phosphogypsum was determined, and the percentage of aluminum and vanadium elements was quantified by chemical and physicochemical methods. Aluminum and vanadium compounds were extracted from the phosphorite ores and from the phosphogypsum for the preparation of aluminum-vanadium nanosorbents. Carbon nanotubes were then grown by chemical vapour deposition over previously adsorbed carbon nanotubes on the aluminum-vanadium nanosorbents (CN-CVD-100 method). Characterization results confirm the successful preparation of nanocatalysts and nanosorbents composed of ready-made aluminum and vanadium carbon nanotubes.
