Due to the global menace caused by carbon emissions from environmental, anthropogenic, and industrial processes, it has become expedient to consider the use of systems, with high trapping potentials for these carbon-based compounds. Several prior studies have considered the use of amines, activated carbon, and other solid adsorbents. Advances in carbon capture research have led to the use of ionic liquids, enzyme-based systems, microbial filters, membranes, and metal-organic frameworks in capturing CO2. Therefore, it is common knowledge that some of these systems have their lapses, which then informs the need to prioritize and optimize their synthetic routes for optimum efficiency. Some authors have also argued about the need to consider the use of hybrid systems, which offer several characteristics that in turn give synergistic effects/properties that are better compared to those of the individual components that make up the composites. For instance, some membranes are hydrophobic in nature, which makes them unsuitable for carbon capture operations; hence, it is necessary to consider modifying properties such as thermal stability, chemical stability, permeability, nature of the raw/starting material, thickness, durability, and surface area which can enhance the performance of these systems. In this review, previous and recent advances in carbon capture systems and sequestration technologies are discussed, while some recommendations and future prospects in innovative technologies are also highlighted.

碳捕集的新型系统和膜技术

由于环境,人为和工业过程中的碳排放所造成的全球威胁,考虑使用对这些碳基化合物具有高捕集潜力的系统已变得很方便。先前的一些研究已经考虑使用胺,活性炭和其他固体吸附剂。碳捕集研究的进步导致使用离子液体,基于酶的系统,微生物过滤器,膜和金属有机框架来捕集CO 2。因此,众所周知,这些系统中的某些系统会出现故障,从而提示需要优先考虑和优化其合成路线以获得最佳效率。一些作者还认为需要考虑使用混合系统,该系统具有几个特征,这些特征反过来提供的协同效应/性能要比组成复合材料的单个组件更好。例如,某些膜本质上是疏水的,这使其不适合碳捕获操作;因此,有必要考虑修改诸如热稳定性,化学稳定性,渗透性,原料/起始材料的性质,厚度,耐久性和表面积之类的特性,这些特性可以增强这些系统的性能。在这篇评论中
