The present work describes the use of yttria stabilized ZrO₂ support. Different loadings (5, 10, 15 and 20 wt%) of yttria were used. The catalysts were tested for CH₄ reforming with CO₂ at 700 °C. The effect of doping Y₂O₃ with ZrO₂ on the catalytic performance was attained. N₂ physisorption (BET), X-ray diffraction (XRD), temperature programmed reduction (TPR), thermogravimetric analysis (TGA), and transmission electron microscopy (TEM) were employed to analyze the used and fresh catalysts. The results showed that Y₂O₃ stabilized ZrO₂ supported catalysts generated the better conversions of CH₄ and CO₂ than nonstabilized ZrO₂ supported catalysts. The mean CH₄ conversions found were 54%, 59%, 60%, 66% and 65% respectively for the 5Ni-ZrO₂, 5Ni-5Y-ZrO₂, 5Ni-10Y-ZrO₂, 5Ni-15Y-ZrO₂ and 5Ni-20Y-ZrO₂. The BET output displayed significant rise in the surface area of the Y₂O₃ satbilized catalysts. The crystallite size of NiO acquired via XRD measurements exhibited remarkable decrease due to the addition of Y₂O_3. TGA and TEM of the spent catalysts showed respectively, reduction of carbon formation as a result of Y₂O₃ addition and formation of multisized nano tubes. The experimentation of the best 5Ni-15Y-ZrO₂ for 40 h produced 60% weight loss of mass and the formation of amorphous carbon on the surface via TGA and TPO respectively.

本工作描述了氧化钇稳定的ZrO ₂载体的使用。使用了不同的氧化钇负载量（5、10、15和20 wt％）。将催化剂用于测试CH ₄与CO重整₂在700℃下。获得了用ZrO ₂掺杂Y ₂ O ₃对催化性能的影响。使用N ₂物理吸附（BET），X射线衍射（XRD），程序升温还原（TPR），热重分析（TGA）和透射电子显微镜（TEM）来分析用过的和新鲜的催化剂。结果表明，Y ₂ O ₃稳定了ZrO ₂负载型催化剂比未稳定的ZrO ₂负载型催化剂产生更好的CH ₄和CO ₂转化率。平均CH _4个转化率发现分别为54％，分别为66％和65％的5Ni-的ZrO 59％，60％，₂，5Ni-5Y-的ZrO ₂，5Ni-10Y-的ZrO ₂，5Ni-15Y-的ZrO ₂和5Ni-20Y-ZrO ₂。BET输出显示出Y ₂ O _3稳定化催化剂的表面积显着增加。通过XRD测量获得的NiO的微晶尺寸由于添加了Y ₂ O ₃而显示出显着的减小_。废催化剂的TGA和TEM分别显示出，由于添加了Y ₂ O ₃而形成的碳减少，并且形成了多尺寸的纳米管。最佳5Ni-15Y-ZrO ₂的实验40 h产生了60％的质量损失，并分别通过TGA和TPO在表面形成了无定形碳。
