Ni supported on CeO₂-SrOmixed oxide catalysts are prepared and studied for bi-reforming of methane with CO₂ in the temperature range of 600 to 800 °C. Characteristics of the prepared catalysts depicted from various spectroscopic techniques. The characterization studies suggested that the presence of SrO enhanced the interaction of Ni with support. The reduction behavior and crystallinity of Ni is also altered with SrO addition to CeO₂. The activity of the catalysts is depended on the CeO₂-SrO mole ratio and Ni content. The catalyst with 12 wt.% Ni and equal mole ratios of CeO₂-SrO showed better activity. The catalyst showed extraordinary stability over a period of 250 h.

制备了负载在CeO ₂ -SrO混合氧化物催化剂上的Ni，并研究了在600至800°C的温度下甲烷与CO _2的双转化。各种光谱技术描述了制备的催化剂的特性。表征研究表明，SrO的存在增强了Ni与载体的相互作用。通过向CeO _2中添加SrO，Ni的还原行为和结晶度也会改变。催化剂的活性取决于CeO ₂ -SrO的摩尔比和Ni含量。具有12重量％的Ni和相等摩尔比的CeO ₂ -SrO的催化剂显示出更好的活性。催化剂在250小时内显示出非凡的稳定性。
