Periclase type Ni/Mg/Al mixed-metal oxide prepared from sol-gel derived SiO₂@Ni-Mg-Al Layered Double Hydroxides (LDH) nanocomposite at SiO₂:LDH ratios 0:1 and 1:1 was used as a catalyst for catalytic partial oxidation (CPO) of CH₄ in presence of N₂O as well as oxygen. The catalysts were characterized by XRD, BET surface area, H₂-TPR and XPS analysis. The presence of SiO₂ dispersant influenced the catalytic property. The nascent oxygen formed by the decomposition of N₂O does not re-oxidize Ni⁰ like molecular oxygen which act as the active species and leads to partial oxidation of CH₄. SiO₂@Ni-Mg-Al (1:1) catalyst showed about 99.99% H₂ and 99.8% CO yield between the temperature range of 200-500 °C.

由溶胶-凝胶衍生的SiO ₂ @ Ni-Mg-Al层状双氢氧化物（LDH）纳米复合物以SiO ₂：LDH比0：1和1：1制备的过氧化物酶型Ni / Mg / Al混合金属氧化物用作催化剂N ₂ O和氧气存在下CH _4的催化部分氧化（CPO）反应。通过XRD，BET表面积，H ₂ -TPR和XPS分析来表征催化剂。SiO ₂分散剂的存在影响了催化性能。由N ₂ O分解形成的新生氧不会像分子氧那样重新氧化Ni ⁰，而分子氧会作为活性物质并导致CH _4的部分氧化。二氧化硅₂在200-500℃的温度范围内，@ Ni-Mg-Al（1∶1）催化剂显示出约99.99％的H ₂和99.8％的CO产率。
