One‐Pot Preparation of Ni2P/γ‐Al2O3 Catalyst for Dehydrogenation of Propane to Propylene

Abstract The γ‐Al 2 O 3 supported Ni 2 P catalysts for propane dehydrogenation were prepared by one‐pot method and evaluated to study the platinum‐like behaviour of Ni 2 P. The catalysts were characterized by X‐ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy‐dispersive X‐ray Spectrometer (EDS), N 2 adsorption at −196 o C and temperature‐programmed desorption of ammonia (NH 3 ‐TPD). Results show that Ni 2 P is beneficial to the catalytic stability. It exhibits higher conversion for PDH of 23.8% and propylene selectivity of 74.4%.
