离子液体被认为是一种很有前途的CO2捕集溶剂，但有些离子液体的吸附容量很低，有些离子液体有毒，而且大多数离子液体价格昂贵。这些特性使得离子液体的应用不那么高效、绿色和经济。提出了评价离子液体捕集CO2效果的标准。吸附容量（C）是表征CO2捕集效率的绝对标准。除了容量外，离子液体的毒性（T）和价格（P）也是影响离子液体工业应用的重要因素。因此，提出了容量-毒性比（Rg=C/T）、容量-价格比（Re=C/P）和容量-毒性-价格比（Rge=C/TP）分别作为评价离子液体捕集CO2的绿色性、经济性和绿色经济性的相对标准。更实际地，复合标准Ri| C>0.5，即Ri大于0.5的阈值容量，以相对值表示，包括综合绿色标准、综合经济标准和综合绿色-经济标准，综合考虑了离子液体捕集CO2的绝对值和相对值。这些标准将联合收割机的高效、绿色和经济的CO2捕集结合在一起。它们被用来审查以前的结果的实用性的二氧化碳捕获的离子液体。从这些标准中得到启示，将来的绿色和经济型离子液体的设计也可能是有利的。
Ionic liquids (ILs) are deemed as promising solvents for CO2capture in the near future, however, some of them have very low sorption capacity, some of them are toxic, and most of them are expensive. These characters make the application of ILs not so efficient, green, and economic. Criteria were proposed to evaluate the utility of CO2capture by ILs in this study. The sorption capacity (C) is an absolute criterion to characterize the efficiency of the CO2capture. Besides capacity, the toxicity (T) and the price (P) of the ILs are also important for the industrial application of ILs. Thus, the capacity–toxicity ratio (Rg=C/T), the capacity–price ratio (Re=C/P), and the capacity–toxicity–price ratio (Rge=C/TP), were proposed as relative criteria for assessing the greenness, the economy, and the green-economy for CO2capture by ILs, respectively. More practically, composite criteria Ri|C>0.5, which mean Riwith a threshold capacity greater than 0.5 expressed with the relative value, including composite greenness criterion, composite economy criterion, and composite greenness-economy criterion, were proposed with considering both the absolute and relative values for CO2capture by ILs. These criteria combine the efficient, green, and economical of CO2capture together. They were used to review the utility of pervious results for CO2capture by ILs. The design of green and economical ILs in the future might also be favorable by taking the hint from these criteria.
