In this study,
Co based catalysts (0.5- 5 wt% Co) supported on sulfated zirconia were prepared
for NO selective reduction by methane . The effect of Co loading on the
catalyst structure, the catalytic activity and stability, as well as the
deactivation rate by 6vol% water in the feed are reported. The best results
were obtained with catalysts up to 2wt% Co loading. XPS and DRS analyses
indicated the existence of the Co+2 in fresh samples. The higher
activity was shown by a catalyst containing Co+2 species in
octogonal position supported on
sulfated zirconia having
tetragonal-monoclinic structure.
