A novel material, designated Ru/ZrO₂@C(MIL), was prepared by thermal transformation of metal organic framework (MOF), MIL-140C-10, in which 10 % of the conventional biphenyl-dicarboxylate linkers had been substituted with bipyridyl-dicarboxylate linkers, thereby providing sites for Ru coordination with the framework. This MOF precursor was compositionally and morphologically transformed when heated, at 500 °C, in a mixture of H₂ and CO₂ (3:1). The transformation afforded a high surface area product (114 m²/g) with exceptional stability and high Ru metal dispersion which was very effective as catalyst for the hydrogenation of CO₂ to CH₄, giving a CH₄ production of 53 mol/g Ru/h (at 350 °C, 40 bar and WHSV 344 L/h/g cat.). TEM results show that the active form of the catalyst was a partially degraded (‘unzipped’) MOF structure where Ru° and ZrO₂ nanoparticles (2−5 and 10−20 nm diameter, respectively) were dispersed upon carbonaceous ribbons.

通过金属有机骨架（MOF）MIL-140C-10的热转化制备了一种命名为Ru / ZrO ₂ @C（MIL）的新型材料，其中10％的常规联苯二羧酸酯连接基已被联吡啶取代-二羧酸酯连接基，从而提供用于Ru与框架配位的位点。当在500°C下于H ₂和CO ₂（3：1）的混合物中加热时，该MOF前体会发生成分和形态上的转变。该转变提供具有高稳定性的高表面积产物（114m ² / g）和高Ru金属分散体，这对于将CO ₂加氢成CH ₄，产生CH _4而言是非常有效的催化剂。生产量为53 mol / g Ru / h（在350°C，40 bar和WHSV 344 L / h / g cat。下）。TEM结果表明，催化剂的活性形式为部分降解（“未压缩”）的MOF结构，其中Ru°和ZrO ₂纳米粒子（分别为2-5和10-20 nm直径）分散在碳带上。
