The present invention relates to the technical field of new catalytic materials, and specifically relates to a phosphorus-doped nickel-aluminum oxide, its preparation method and the application thereof. Said preparation method comprises: the nickel-aluminum-based layered double hydroxide is subjected to high-temperature aerobic calcination to obtain nickel-aluminum oxide, the nickel-aluminum oxide obtained thereby is mixed with a phosphorus source and heated in an inert gas atmosphere or in vacuum conditions to dope phosphorus into the nickel-aluminum oxide, whereby the final phosphorus-doped nickel-aluminum oxide is obtained. In the present invention the NiAl interactions are constructed by subjecting the nickel-aluminum based layered double hydroxides to aerobic calcination at high temperature. The NiP interactions are constructed by doping P into nickel-aluminum oxides. Thus, the synergistic interactions of NiAl and NiP achieve regulating the electron density around the P-active metals, wherein the active metal is in an intermediate phase between metal and metal phosphide, which suppresses the factors leading to deactivation of the catalyst, such as metal agglomeration, carbon deposition, and phase transformation, demonstrating excellent catalytic activity, selectivity and stability.
