Porous materials have attracted much attention for carbon capture and in the recent past; they have witnessed significant advancements in their design and implementation for CO₂ capture and conversion. In this context, the emerging trends in major porous adsorbents such as MOFs, zeolites, POPs, porous carbons, and mesoporous materials for CO2 capture and conversion are discussed. Their surface texture and chemistry, and the influence of various other features on their efficiency, selectivity, and recyclability for CO₂ capture and conversion are explained and compared thoroughly. The scientific and technical advances on the material structure versus CO₂ capture and conversion provide deep insights into designing effective porous materials. The review concludes with a summary, which compiles the key challenges in the field, current trends and critical challenges in the development of porous materials, and future research directions combined with possible solutions for realising the deployment of porous materials in CO₂ capture and conversion.]]> Wed 14 Dec 2022 16:09:47 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36012 Thu 20 Feb 2020 11:37:15 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17212 Sat 24 Mar 2018 07:59:17 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48089 Fri 24 Feb 2023 15:16:54 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41089 Fri 22 Jul 2022 17:18:26 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38191 2 capture. For instance, solution absorption is promising due to a large processing capacity, high flexibility and reliability, and rich experience in engineering applications. Nonetheless, actual commercial solutions, solvents and processes for CO₂ capture suffer from slow reaction kinetics, low absorption capacity, high-energy consumption, susceptibility to corrosion, toxicity, low stability and high costs. Therefore, current research focuses on developing more economical, effective, green and sustainable technologies. Here we review 2015–2020 findings on CO₂ capture using liquid absorption methods. Methods are based on various solutions, solvents and processes such as carbonate solution, ammonia solution, amine-based solution, ionic liquid, amino acid salt, phase changing absorbent, microcapsulated and membrane absorption, nanofluids and phenoxide salt solution. We discuss absorption performance, absorption mechanism, enhancement pathways and challenges. Amine- and NH₃-based absorbents are widely used, yet they are limited by high regeneration energy, corrosiveness and degradation, reagent loss and secondary pollution caused by NH₃ escape. Phase changing absorbents are getting more attention due to their lower cost and lower energy penalty. The incorporation of membrane and microencapsulation technologies to absorbing solvents could enhance CO₂ absorption performance by reducing corrosion and increasing selectivity. Adding nanoparticles to solvents could improve CO₂ absorption performance and reduce energy requirement. Besides, solvent blends and promoter-improved solvents performed better than single and non-promoted solvents because they combine the benefits of individual solvents and promoters.]]> Fri 22 Apr 2022 14:02:14 AEST ]]>
