摘要: Abstract Mesoporous nanocrystalline zirconia with high-surface area and pure tetragonal crystalline phase has been prepared by the surfactant-assisted route, using Pluronic P123 block copolymer surfactant. The synthesized showed a surface of 174 m2 g−1 after calcination at 700 °C for 4 h. was employed as support nickel catalysts in dry reforming reaction. It found that these possessed mesoporous structure even area. activity results indicated catalyst stable syngas production decrease about 4% methane conversion 50 h Addition promoters (CeO2, La2O3 K2O) to improved both stability catalyst, without any
