Abstract:
Silica aerogels comprising nickel oxide nanoparticles were synthesized with no use of supercritical drying. A high specific surface area (more than 1000 m2/g), mesoporous structure and considerable stability to sintering up to 900 °C are characteristic of these aerogels. The aerogels were synthesized using the sol–gel method. Filamentous carbon was templated by silica, tetraethoxysilane being used for supplying silica. Carbon was burnt later. Analysis of the aerogel structure revealed the presence of silica nanotubes and nanofibers. Aerogel testing for direct oxidation of H2S into S0 demonstrated as high as 60% conversion of hydrogen sulfide at almost 100% selectivity under stoichiometric conditions at the temperature range of 300–350 °C and 73% conversion at 100% selectivity at a considerable excess of oxygen at 160 °C.
