In dry methane reforming, the selection of a suitable support is critical due to coke formation and metal particle sintering. We prepared two types of mesoporous defect spinel magnesium aluminate support, namely DS09, with a Mg/Al molar ratio (Mg/Al) of 0.1, and DS19 with Mg/Al = 0.24. Each support has a high surface area, large mesopore volume, and a phase between its defect spinel (Mg_0.388Al_2.408O₄) and spinel (MgAl₂O₄) structures. Magnesium aluminate with a Mg/Al of 0.5 (MG30), which has a low surface area and is devoid of mesopores, was used as the reference support. Ni was supported on DS09 (Ni-DS09) and DS19 (Ni-DS19) by A-site exsolution. These catalysts display significant advantages over Ni-supported MG30 (Ni-MG30); Ni-DS19 exhibited a higher coke resistance than Ni-DS09, due to its lower acidity, while DS19, which contains a defect spinel structure, optimized acidity, and well-developed mesopores, was the best support for the DMR.

在干甲烷重整中，由于焦炭形成和金属颗粒烧结，选择合适的载体至关重要。我们制备了两种类型的介孔缺陷型尖晶石铝酸镁载体，即Mg / Al摩尔比（Mg / Al）为0.1的DS09和Mg / Al = 0.24的DS19。每个支撑物具有高的表面积，大的中孔体积以及在其缺陷尖晶石（Mg _0.388 Al _2.408 O ₄）和尖晶石（MgAl ₂ O _{4）之间的相}）结构。Mg / Al为0.5（MG30）的铝酸镁具有较低的表面积且没有中孔，被用作参考载体。通过A站点放样在DS09（Ni-DS09）和DS19（Ni-DS19）上支持Ni。这些催化剂比镍负载的MG30（Ni-MG30）表现出显着的优势。Ni-DS19由于其较低的酸度而比Ni-DS09表现出更高的耐焦炭性，而具有缺陷尖晶石结构，优化的酸度和发达的中孔的DS19是DMR的最佳支持。
