• La–Ni–SZA catalyst exhibits highest isomerization activity at lower temperature.
• The addition of Ni can promote redox performance of catalyst.
• The Ni metal can promote the formation of Lewis acid sites.
• The addition of La could lead to a higher dispersion of metal and more acid sites.
The La –Ni–S2O82−/ZrO2 –Al2O3 (La–Ni–SZA) was prepared and the effect of La and Ni on the structure and isomerization performance of catalyst was investigated. The addition of La could lead to a higher dispersion of metal and more acid sites. The addition of Ni can promote redox performance of catalyst and formation of Lewis acid sites. The highest isopentane yield of 66.5% at a lower reaction temperature of La–Ni–SZA can be attributed to the synergistic interaction between La and Ni.
