Mesoporous carbon activated with HNO 3 was demonstrated to be robust metal-free catalyst for direct dehydrogenation of propane without any auxiliary stream, exhibiting high selectivity and stability. The final propane conversion is 22.4% with stable propylene selectivity of 86.6% after 50hours. HNO 3 activation introduces more basic oxygen groups than the pristine carbon, which is...
Fiber-like high-surface-area attapulgite (APT) clay was used as a support of CuO particles, and the textural and structural properties of the prepared CuO/APT catalysts were characterized by X-ray diffraction, scanning and transmission electron microscopy, N 2 sorption analysis and X-ray photoelectron spectroscopy. The catalytic behavior of the prepared CuO/APT catalysts for low-temperature...
