The oxidative dry reforming of CH₄ (ODRM) was studied at 500-800 °C in harsh conditions (CH₄/CO₂/O₂/N₂ = 1:0.7:α:N₂ with 20% of CH₄, 96,000 mLh^-1g_cat^-1 and α varying from 0 up to 0.5) on CeNi_XAl_0.5H_ZO_Y (0.5 ≤ x ≤ 5) nano-oxyhydride catalysts. At low temperature (500-600 °C), the conversion of CH₄ reaches the thermodynamic limit while those of CO₂ overcomes the predicted value in particular at 500 °C. At 600 °C with an O₂/CH₄ ratio of 0.3, the CeNi₂Al_0.5H_ZO_Y catalyst allows getting CH₄ and CO₂ conversions of about 63% and 50 %, respectively, and a H₂/CO ratio of about 1.3, without carbon formation. The physico-chemical characterizations performed before and after test show the existence of strong interactions existing between Ni²⁺ cations with other cations and the presence of nano-oxyhydride compound. The mixed oxide based nano-materials corresponding to hydride reservoirs with the presence of Ni²⁺ cations are shown to be highly active, selective and stable catalysts.

氧化干燥CH重整₄（ODRM）进行了研究，在（500-800℃，在恶劣条件下CH ₄ / CO ₂ / O ₂ / N ₂ = 1：0.7：α：N ₂与CH的20％₄，96000在CeNi _X Al _0.5 H _Z O _Y（0.5≤x≤5）纳米氢氧化物催化剂上，mLh ^-1 g _cat ^-1和α从0到0.5变化。在低温（500-600°C）下，CH ₄的转化率达到热力学极限，而CO ₂的转化率尤其在500°C时超过了预测值。在600°C和O _2下/ CH ₄比率为0.3，CeNi ₂ Al _0.5 H _Z O _Y催化剂可使CH ₄和CO ₂转化率分别约为63％和50％，H ₂ / CO比率约为1.3，而不会形成碳。测试之前和之后进行的物理化学表征表明，Ni ²⁺阳离子与其他阳离子之间存在强相互作用，并且存在纳米氧化氢化合物。与存在Ni ²⁺阳离子的氢化物储层相对应的混合氧化物基纳米材料显示为高活性，选择性和稳定的催化剂。
