ABSTRACT / САЖЕТАК:

The influence of carbonization temperature in the synthesis of Co-supported hybrid inorganic- organic carbon-smectite catalysts was investigated. The catalysts wеre synthetized by simultaneous intercalation of inorganic Al-Keggin cations and organic hexadecyltrimethylammonium cations, followed by wet impregnation by Co2+ ions. The obtained samples were carbonized at 400 °C, 500°C, and 600 °C in the flow of Ar providing inert atmosphere. The textural properties were obtained based on adsorption-desorption isotherms of nitrogen at -196 °C. The synthesized nanocomposites were tested as heterogeneous catalysts in advanced oxidation process of Acid Orange G degradation in the presence of Oxone® (2KHSO5·KHSO4·K2SO4). It was found that catalyst obtained by carbonization at 400 °C has the most developed surface area and showed the highest percent of degradation of Acid Orange G.
