| Abstract: | In this work,we heve made an investigation on promoter effects of oxide of rare earth (La,Ce, Pr,Nd)in Ni/r-Al_2O_3 system.Great concentration of Ni atom in surface of was caused by Additive of promoter,and the metal Nickel was dispersed in grain.It is possible that this effects is concerned with the nature of rare earth elements. |
