Abstract

The surface of a carbon fiber made of viscose has been modified with sulfur vapors in the temperature range of 400–800 °C with further oxidation of the obtained materials with hydrogen peroxide, as a result of which carbon fiber samples containing sulfur-containing acid groups on the surface have been synthesized. The samples have been investigated in a model reaction – gas-phase dehydration of isopropanol with the formation of propylene. It has been shown that the materials obtained have considerable thermal stability and high catalytic activity – the complete conversion of isopropanol to propylene is observed at a temperature of 140–180°C.
