二氧化碳為一種溫室氣體,其無毒且大量豐富存在於自然界中,價格低廉,也是許多化學製造過程中所生成的廢棄物。若可回收再利用,除了減少溫室氣體,也能將其轉換成可利用資源。本計畫以N-heterocyclic carbenes (NHCs)化合物為基本架構,並引入官能基設計和開發新穎的配位基。藉由新穎含NHCs配位基所形成的均相及非均相金屬錯化合物將可應用於二氧化碳回收再利用反應,藉此將二氧化碳轉換成高經濟價值資源。 本研究計劃之目的有三項:(1)新穎配位基均相及非均相金屬錯化合物(包括鎂、鋁、鉻、鐵、鈷與鎳錯化合物)之設計、合成開發及結構鑑定研究,並希望了解此類化合物的化學結構與催化機制之間的關係。(2)利用所開發之金屬錯化合物作為二氧化碳回收再利用反應之觸媒以及其催化活性研究和探討。(3)篩選較具潛力之金屬錯化合物進行催化活性研究。
Carbon dioxide is a greenhouse gas as it is non-toxic, abundant, inexpensive, and the waste product of many chemical processes. If it can be recycled and reused, we can not only reduce greenhouse gases, but also be converted into useful resources. Therefore, we are interesting to develop homogeneous and heterogeneous catalyst for CO2 reuses. Novel multi-chelated ligands are designed and developed by the combinations of the side chain functionality and the backbone unit that is N-heterocyclic carbene (NHC) derivative. Well-defined metal complexes incorporating NHC ligands will be synthesized, structurally characterized and employed toward CO2 reaction. The purpose of this research project is threefold: (1) to design, synthesis, and characterize novel metal complexes supported by N-heterocyclic carbene derivative (including magnesium, aluminum, chromium, iron, cobalt, and nickel complexes). (2) to use those complexes as a catalysts for carbon dioxide recovery and reuse reaction and their catalytic studies and discussions for these reactions. (3) to select high potential catalysts for CO2 reaction and their investigations of catalytic activities.
