CO 2 conversion will be at the core of the future of low-carbon chemical and energy industry. This review gives a glimpse into the possibilities in this field by discussing (i) CO 2 circular economy and its impact on the chemical and energy value chain, (ii) the role of CO 2 in a future scenario of chemical industry, (iii) new routes for CO 2 utilization, including emerging biotechnology routes, (iv) the technology roadmap for CO 2 chemical utilization, (v) the introduction of renewable energy in the chemical production chain through CO 2 utilization, and (vi) CO 2 as a suitable C-source to move to a low-carbon chemical industry, discussing in particular syngas and light olefin production from CO 2 . There are thus many stimulating possibilities offered by using CO 2 and this review shows this new perspective on CO 2 at the industrial, societal and scientific levels.

“…This movement is termed as metal-to-ligand charge transfer process. Back-electron transfer from the ligands to the metal after the charge transfer is prevented by including an electron-donating species to quench the exciting state of the photocatalyst, thus forming the one-electron-reduced (OER) intermediate for further CO 2 reduction processes 87 .…”

Using carbon dioxide as a building block in organic synthesis

Carbon dioxide exits in the atmosphere and is produced by the combustion of fossil fuels, the fermentation of sugars and the respiration of all living organisms. An active goal in organic synthesis is to take this carbon-trapped in a waste product-and re-use it to build useful chemicals. Recent advances in organometallic chemistry and catalysis provide effective means for the chemical transformation of CO 2 and its incorporation into synthetic organic molecules under mild conditions. Such a use of carbon dioxide as a renewable one-carbon (C1) building block in organic synthesis could contribute to a more sustainable use of resources.A more sensible resource management is the prerequisite for the sustainable development of future generations. However, when dealing with the feedstock of the chemical industry, the level of sustainability is still far from satisfactory. Until now, the vast majority of carbon resources are based on crude oil, natural gas and coal. In addition to biomass, CO 2 offers the possibility to create a renewable carbon economy. Since pre-industrial times, the amount of CO 2 has steadily increased and nowadays CO 2 is a component of greenhouse gases, which are primarily responsible for the rise in atmospheric temperature and probably abnormal changes in the global climate. This increase in CO 2 concentration is largely due to the combustion of fossil fuels, which are required to meet the world's energy demand 1 . Obviously, there is an urgent need to control CO 2 emissions and develop efficient carbon capture systems. Although the extensive use of carbon dioxide for chemical production cannot solve this problem alone, CO 2 is a useful one-carbon (C1) building block in organic synthesis due to its abundance, availability, nontoxicity and recyclability. As a result, valorization of CO 2 is currently receiving considerable and ever increasing attention by the scientific community 2-4 . However, activation and utilization of CO 2 is still problematic due to the fact that it is the most oxidized form of carbon, which is also thermodynamically stable and/or kinetically inert in certain desired transformations. Consequently, most of the known studies used highly reactive substrates and/or severe reaction conditions to activate CO 2 , limiting the application of such methods. In particular, the catalytic coupling of CO 2 with energy-rich substrates, such as epoxides and aziridines, to generate polycarbonates/polycarbamates and/or cyclic carbonates/carbamates has drawn significant attention over the past decades. To create C-C bonds with CO 2 , the use of carbon nucleophiles is specifically limited to strong nucleophilic organolithiums and Grignard reagents, as well as phenolates.

“…In this regard, a number of heterogeneous catalysts including metal oxides, sulphides, nitrides and oxynitrides have been investigated for CO 2 reduction, albeit lower quantum yields and poor selectivities are the major drawbacks [33][34][35]. Molecular catalysis, particularly, based on transition metal complexes, such as rhenium(I) bipyridine, ruthenium(II) polypyridine carbonyl, cobalt (II) trisbipyridine, and cobalt (III) macrocycles in combination with a photosensitizer have been considered to be high performance photocatalysts for CO 2 reduction with relatively high quantum yield and high selectivity of products [36][37][38][39]. However, the homogeneous nature and non-recycling ability of these catalysts make them impractical from economical as well as environmental viewpoints.…”
