Ni-based catalysts are solid heterogeneous catalysts which are composed of fine grain of porous nickel-aluminum alloy. Ni-based catalysts have many advantages

such as high mechanical strength

good catalytic activity

simple preparation and low price. Ni-based catalysts have been widely used in the process of conversion reaction of hydrogenation

dehydrogenation

dehalogenation and desulfurization in petroleum

chemical

pharmaceutical

oil

perfume

hydrogen peroxide

synthetic fiber and so on. However

the requirements on the catalyst performance are increasingly high with the gradual development of industrial catalysis

the defect of the Ni-based catalysts such as the utilization rate is low

acid resistance is bad also expose undoubtedly. Therefore

in recent years

researchers have been trying to change the performance of Ni-based catalysts such as working life

catalytic activity

anti-acid. The strengthening measures and the application of Ni-based catalysts are emphasized in this paper. The applications of Ni-based catalysts in various catalytic reactions are also outlined in detail. Finally

the future development of Ni-based catalysts is prospected.
