Double-Active Membranes for a sustainable CO2 cycle

化石燃料的开采使我们的生态系统处于灾难性变化的边缘。人类目前的挑战是扭转温室气体排放量的增加，以减轻对全球气候的严重后果。在这种情况下，必须加快现代社会向更可持续和循环经济的过渡。这一转变的关键支柱之一是基于净零排放的碳捕获和利用过程实施可持续的二氧化碳循环。基于膜的技术可以发挥关键作用，使这一愿景更接近现实。事实上，由于其高效率，可扩展性，易于操作性，它们是有效捕获和利用CO2的候选人。DAM 4CO 2的目标是开发一种新型膜技术，用于同时分离CO2并将其光催化转化为C4+分子，作为可再生燃料。DAM 4CO 2将通过开发具有耐用且高选择性的气体分离层和光催化层的双活性膜（DAM）来克服常规膜技术，所述双活性膜（DAM）能够在一锅法中同时联合收割机结合反向水煤气变换（RWGS）和费托合成（FTS）以获得C4+分子。该项目将提供一个原型，使用设计-构建-测试学习方法设计，用于实验室条件下的概念验证。将密切关注工艺每一阶段非关键原材料的使用，并通过全生命周期分析认证整个工艺的碳中和。DAM 4CO 2汇集了我们团队在有机、无机和物理化学、材料科学和化学工程领域的互补专业知识，用于原材料的开发、合成和表征，以及膜组件的设计、建造和应用。DAM 4CO 2将实施可持续、成本和能源有效的净零碳二氧化碳循环。

The exploitation of fossil fuels brought our ecosystem on the edge of catastrophic changes. Mankind’s current challenge is to reverse the increase of greenhouse gases emissions to mitigate the serious consequences on the global climate. In this scenario, the transition of modern society to a more sustainable and circular economy must be accelerated. One of the key pillars of this transition is the implementation of a sustainable CO2 cycle, based on net-zero emissions Carbon Capture and Utilization processes. Membrane-based technologies could play a pivotal role to bring this vision closer to reality. Indeed, thanks to their high efficiency, scalability, easy operability, they are candidates for the efficient capture and use of CO2. The goal of DAM4CO2 is to develop a novel membrane technology for the simultaneous CO2 separation and its photocatalytic conversion to C4+ molecules, as renewable fuels. DAM4CO2 will overcome the conventional membrane technologies by developing double active membranes (DAMs) with a durable and highly selective gas separation layer and a photocatalytic layer able to simultaneously combine in one pot reverse water gas shift (RWGS) and Fisher-Tropsch synthesis (FTS) to obtain C4+ molecules. The project will deliver a prototype, designed using the design-build-testlearn approach, for a proof-of-concept validation in lab-conditions. Close attention will be paid to the use of non-critical raw materials at every stage of the process, and the carbon-neutrality of the entire process will be certified by a full life cycle analysis. DAM4CO2 brings together the complementary expertise of our team in the areas of organic, inorganic and physical chemistry, materials science, and chemical engineering for the development, synthesis, and characterization of the starting materials, and for the design, construction, and application of membrane modules. DAM4CO2 will implement a sustainable, cost and energy effective net zero carbon CO2 cycle.
