While amino-containing materials excel in capturing CO₂, they generally suffer from a few limitations, namely, the high energy penalty for desorption and the obstacle to directly convert CO₂ into valuable resources. In this context, molecular or polymeric compounds based on <em>N</em>-heterocyclic carbenes (NHCs) have emerged as versatile alternatives to efficiently sequester CO₂. NHCs are among the most investigated reactive species in chemistry: not only have they been intensively used as ligands for transition metal catalysts but also they exhibit a rich chemistry, either as true reagents or as organic catalysts. However, their air- and moisture-sensitivity represents a limitation to their use in synthesis. As reviewed thereafter, NHCs can selectively react with CO₂ forming stable adducts, in the form of zwitterionic betaine-type species, providing CO₂ directly-on-site for further fixation. Advances in the use of NHCs in this field are illustrated in this paper with a special emphasis on integration of NHCs in materials enabling heterogeneous utilizations in capture and catalysis.</p></div>","PeriodicalId":101195,"journal":{"name":"Sustainable Chemistry for Climate Action","volume":"2 ","pages":"Article 100018"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49732903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the past, the vast investment in renewable technology is allowing today's rapid deployment. Why is this not currently happening in the CO₂ capture area? This bibliometric analysis which focused on the use of solid sorbents in the CO₂ capture field between 2001 and 2021, aims to answer these questions. The study reviewed three capture methods: post-combustion, pre-combustion and DAC, with particular emphasis on the latter. To understand the evolution of DAC, this novel approach highlights which authors and countries have been investigating the use of solid sorbents. The outcomes of this research showed that, during the first decade, there was a minor interest in funding and investigating solid sorbents for DAC solutions. It was only at the end of the second period when the use of these materials in the topic emerged to the surface. Acting as an example, the United States, China and the United Kingdom spent more financial help to investigate the use of sorbents. However, all of today's CO₂ capture plants are working for enhanced oil recovery. In the Republic of Ireland, there are a few articles exploring the use of these materials to uptake CO₂. It is possible that certain articles were not considered by the software. Upcoming analysis will answer this question and include all the existing materials in the wide spectrum of solid sorbents at the CO₂ capture field.</p></div>","PeriodicalId":101195,"journal":{"name":"Sustainable Chemistry for Climate Action","volume":"1 ","pages":"Article 100009"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772826922000086/pdfft?md5=74cd551e8a08ea392c86ebd08542327e&pid=1-s2.0-S2772826922000086-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81430543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, the activation of CO₂ is challenging and energy-intensive and today the production of one oxalate molecule first requires the reduction of two CO₂ molecules. Recently we confirmed the crucial role of the reactive carbonite intermediate in the FOCR. Due to its high reactivity, this intermediate might also be a strong enough nucleophile to react with CO₂ directly. If this is the case, we can form oxalate directly from CO₂ and formate and avoid the need for double electrochemical CO₂ reduction in oxalate production. In this work, we successfully established the conversion of CO₂ (with a theoretical yield of 52%) to oxalate (via the reaction with carbonite), as well as to formate and carbonate. The direct reaction of the reactive carbonite intermediate with CO₂ was the dominant pathway for CO₂ incorporation in oxalate. For enhancing the CO₂ incorporation in oxalate, we found a reaction temperature of 200°C, stoichiometric amounts of the base, and the presence of CO₂ in the supercritical state most suitable. The residence time is strongly depending on the reactor type but should be kept to a minimum to avoid carbonate formation. The presence of high amounts of hydride and supercritical CO₂ appeared to also cause the formation of carbonates as a side-product. The carbonate formation increased with higher temperatures and longer reaction times, which suggests a consecutive decomposition of oxalate formed in the reaction.</p></div>","PeriodicalId":101195,"journal":{"name":"Sustainable Chemistry for Climate Action","volume":"1 ","pages":"Article 100001"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772826922000013/pdfft?md5=235bb51faf7c1bded18cf51e9ee6f096&pid=1-s2.0-S2772826922000013-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136850567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conventional energy- and carbon-intensive ammonia production industry is taking serious steps in transforming to more environmentally benign pathways via utilizing ‘green’ hydrogen (hydrogen production via water electrolysis powered by renewable energy) feedstock into their production process and utilizing more of the CO₂ by-product into downstream processes such as urea production. However, it is very challenging for ammonia and other fertilizer production routes to use ‘green’ pathway to completely decarbonize agriculture and food industry. Here, we argue that urea synthesis can only be considered as a ‘green’ technology if ammonia feedstock is produced via a ‘green’ pathway and the CO₂ feedstock comes from non-fossil-fuel and carbon-neutral sources. Three possible resources for carbon-neutral CO₂ are identified and discussed within Australia's context: from biomass, renewable methane, and from direct air carbon capture (DAC). Each of these carbon-neutral CO₂ routes has many opportunities and challenges that may affect the cost of production, but the trajectory urea prices and growing market demand if supported by an adequate government regulatory framework would be able to make the ‘green’ urea production cost affordable. Achieving this goal however would require proper energy management systems to synchronize and optimize such a multi-player orientation for a common objective of maximizing the penetration of renewable sources at competitive costs. In this review, it is emphasized that this challenge could be addressed more effectively via a rigours intelligent energy network (IEN) by managing the dynamics of the supply and demand, integrating reliable storage systems, reclaiming the waste heat, and improving process efficiencies. Local ‘green’ urea production at competitive costs would help Australia realizing ambitions to become a leading green fertilizer and renewable energy exporter in the region.</p></div>","PeriodicalId":101195,"journal":{"name":"Sustainable Chemistry for Climate Action","volume":"1 ","pages":"Article 100008"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772826922000074/pdfft?md5=1ea8f309e82f040050d0b83918b2a4b2&pid=1-s2.0-S2772826922000074-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79127461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
