Hard template route for synthesis of mesoporous spinel type oxides with ordered structure

The binary mesoporous spinel oxides with high surface area have been synthesized by. using KIT-6 and SBA-15 as hard templates and hydrated nitrated salts as precursors. Low temperature such as 500 degrees C is suitable for preparation of NiCo2O4 with spinel phase. High temperature such as 800 degrees C is necessary for preparation of NiMn2O4, MnCo2O4, and (Co0.5Mn0.5)(3)O-4 with pure spine! phase. The prepared mesoporous spinel shows high surface area as 43-105 m(2)/g with pore volume as 0.095-0.233 cm(3)/g. It is preferred to form mesoporous NiCo2O4 with spherical particles.
