Emissions of carbon dioxide (CO2) lead to global warming and climate changes that affect human life and the environment. With the current carbon-capture technologies, there is very little industrial and commercial interest, even in the presence of government incentives. To mitigate the concentration of CO2 in the atmosphere, various strategies have been implemented such as separation, storage, and utilization of CO2. Each stage in the carbon cycle (i.e. capturing, regeneration and conversion) has its own materials requirements. Recent work on metal-organic frameworks (MOFs) demonstrated the potential and effectiveness of these materials in addressing the CO2 challenge. There is an increasing trend to consider carbon dioxide as a resource and a business opportunity rather than a waste product with a cost for disposal. Increasing amounts of low-cost and relatively pure CO2 are available from different industries for carbon sequestration and storage. Hence, CO2 will be a feed-stock of nearly zero (or even negative) cost for conversion to fuels and chemicals. Herein, I propose to develop novel dual functional adsorbents/catalysts (DFA/Cs) based on metal organic framework (MOF) and zeolitic imidazolate framework (ZIF), and use them in the separation/conversion of CO2 into value-added chemicals including but not limited to polycarbonate and poly carbamate polymers. These bio-polymers will be entitled to carbon credits. These two polymers are mainly manufactured using highly toxic phosgene (COCl2), as a key raw material. Replacing phosgene with CO2 will lead to a safer and more eco-friendly technology. The main objective of this proposal is to establish a solid fundamental research program leading to the rational design of a novel family of catalysts, based on MOFs/ZIFs, which offer the possibility of demonstrating high catalytic performance for carbon dioxide conversion to value-added chemicals such as polycarbonate polymers. The specific deliverables of this proposal include: (A) Rational design of a family of MOF/ZIF-based dual functional adsorbent/catalyst (DFA/Cs). (B) Catalytic performance of MOF/ZIF in the conversion of CO2 to polycarbonate polymers. (C) Establish fundamental structure/adsorption/catalytic relationships of MOF/ZIF-DFA/Cs  in separation and conversion of CO2 to polycarbonate polymers using a tubular membrane reactor.

二氧化碳（CO2）的排放导致全球变暖和气候变化，影响人类的生命和环境。借助当前的碳捕捞技术，即使在政府激励措施的情况下，工业和商业利益也很少。为了减轻大气中二氧化碳的浓度，已经实施了各种策略，例如分离，储存和利用CO2。碳周期中的每个阶段（即捕获，再生和转换）都有其自身的材料要求。关于金属有机框架（MOF）的最新工作证明了这些材料在应对CO2挑战方面的潜力和有效性。将二氧化碳作为资源和商机的趋势越来越多，而不是以处置成本的废物。从不同行业获得碳固存和存储的低成本和相对纯二氧化碳的增加。因此，二氧化碳将是转换为燃料和化学物质的近零（甚至负）成本的饲料库。在此，我建议开发基于金属有机框架（MOF）和Zeolitic Imidazaly框架（ZIF）的新型双重功能吸附剂/催化剂（DFA/CS），并将其用于将CO2分离/转换为增值化学物质，包括但不限于多碳酸盐含量和多碳酸盐和聚碳酸酯和聚碳酸酯和聚碳酸酯。这些生物聚合物将有权获得碳信用额。这两种聚合物主要是使用剧毒磷酸盐（COCL2）作为关键原料生产的。用CO2代替Phosgene将导致一项更安全，更环保的技术。该提案的主要目的是建立一项扎实的基本研究计划，从而基于MOFS/ZIFS，从而使新型催化剂家族的合理设计提供了证明二氧化碳转化到增值化学物质（如聚碳酸酯聚合物）的可能性高的催化性能。该提案的具体交付包括：（a）基于MOF/ZIF的双重功能吸附剂/催化剂（DFA/CS）的合理设计。 （b）MOF/ZIF在二氧化碳转化为聚碳酸酯聚合物中的催化性能。 （c）使用管状膜反应器，建立MOF/ZIF-DFA/C的基本结构/吸附/催化关系，并将CO2分离和转化为聚碳酸酯聚合物。
