金属有机框架（MOF）材料是具有高表面积的多孔材料，其表面特性的设计和定制具有巨大的灵活性，可用于多种化学工艺。大多数报道的 MOF 材料性能都是在小规模生产的粉末材料中进行评估的，其中合成已被优化以获得结晶粉末。理想情况下，这些材料的工业化也将与高效的可扩展合成方案相关联。此外，为了将这些材料用作环境友好材料，它们的合成必须是可持续的。我们对四种不同的合成方案进行了从摇篮到大门的生命周期评估，以生产 MOF 材料（CPO-27-Ni 也称为 MOF-74 和 DOBDC），这是一种适合碳捕获和储存（CCS）技术的新型吸附剂材料。我们已经证明，使用 LCA 可以理想化 MOF 材料生态设计的方法。通过我们的分析，我们确定在合成中使用溶剂的影响是相当大的。此外，令人惊讶的是，LCA 分析帮助我们确定清洁和纯化步骤中使用溶剂对环境指标具有同等（甚至更大）的影响。如果可能，应避免使用溶剂；如果不可能消除溶剂，则应考虑再利用策略。
Metal-organic framework (MOF) materials are porous materials with high surface area that offer enormous flexibility of design and tailoring of its surface properties to be used in diverse chemical processes. Most of the reported properties of MOF materials were evaluated in powder materials produced in small scale where the synthesis has been optimized to obtain crystalline powders. Ideally, the industrialization of these materials will also be associated to efficient scalable synthesis protocols. Moreover, for these materials to be used as environmental-benign materials, their synthesis has to be sustainable.We present a cradle-to-gate life-cycle assessment of four different synthesis protocols to produce a MOF material (CPO-27-Ni also termed as MOF-74 and DOBDC) which is one suitable novel adsorbent material for carbon capture and storage (CCS) technologies. We have demonstrated that using a LCA is possible to idealize a methodology for eco-design of MOF materials. With our analysis we have determined that the impact of using solvents in the synthesis is considerable. Moreover, surprisingly, the LCA analysis helped us identifying that the utilization of solvents for the cleaning and purification steps has an equally (or even larger) impact in the environmental indicators. Utilization of solvents should be avoided if possible or reutilization strategies should be envisaged if is not possible to eliminate them.
