The method comprises: (1) washing cubic-textured Ni or Ni alloy belt substrate, and drying; (2) sputtering Ni or Ni alloy substrate with Ce as the target at 500-780 deg.C and 5-80 Pa in Ar / H2 atmosphere for 5-30 min; (3) sputtering Ni or Ni alloy substrate with Ce as the target at 500-780 deg.C and 5-80 Pa in Ar / O2 atmosphere for 25-150 min to obtain a CeO2 buffer layer. The volume ratio of Ar to H2 is (50-80):10. The volume ratio of Ar to O2 is 50:2-80:1. The method can effectively inhibit the formation of NiO, and ensure uniform orientation of CeO2.
