Catalytic properties of nanofibrous carbon in selective oxidation of hydrogen sulphide

Nanofibrous carbonaceous materials (NFC) as a new class of materials having many applications, can catalyze the selective oxidation of H 2S to sulfur. The correlation between NFC structure and its activity and selectivity in H 2S oxidation was determined. It is demonstrated that selectivity can be i...

Summary:Nanofibrous carbonaceous materials (NFC) as a new class of materials having many applications, can catalyze the selective oxidation of H 2S to sulfur. The correlation between NFC structure and its activity and selectivity in H 2S oxidation was determined. It is demonstrated that selectivity can be improved if NFC with more ordered structure be synthesized and the portion of the original catalyst in carbon be reduced by increasing the carbon accumulated in the catalyst.
