The research of the formation of the surface structure of reney catalysts

摘要

The formation of the structure and the phase composition of the surface of Reney catalysts made of Ni--Al alloys depends on relative concentrations of aluminide type phases of NiAl_3 and Ni_2Al_3. Catalyst surface is covered with Ni (a=3,51 A), Al_2O_3 and NiO (2P_(3/2) -- 2,5 eV).
