“…CO 2 , main green‐house gas (GHG), can also be a useful chemical feedstock for the synthesis of value‐added chemicals including aromatic monomers . The use of CO 2 as a chemical feedstock is a challenging task owing to its stable with a fully oxidized nature as well as the highest thermodynamical stability.…”

Value‐added aromatic monomers such as benzene, toluene, and xylenes (BTX) are very important building‐block chemicals for the production of plastics, polymers, solvents, pesticides, dyes, and adhesives. Syngas‐to‐aromatics (STA) is a very promising approach for the synthesis of aromatic monomers, and is catalyzed via bifunctional catalysts in a single reactor, wherein methanol/dimethyl ether and/or olefins intermediates formed from syngas on metal components are converted into aromatic monomers exclusively on the HZSM‐5 by cascade reactions. Since an optimal Fischer–Tropsch synthesis (FTS) temperature of Fe‐based catalysts is very close to an aromatization temperature of HZSM‐5, Fe‐based catalysts have been frequently used/modified for the synthesis of aromatic monomers from hydrogenation of carbon oxides (CO and CO2). The nature of metal components and amounts of Brönsted acid sites on HZSM‐5, and their mesoporosity and intimacy, significantly alter the selectivity for aromatics by tuning BTX distibution and catalyst stability. Although many developments have been achieved regarding the STA process in recent years, no reviews have been published in this flourishing research area over the last two decades. Here, the recent advances and forthcoming challenges in the progress of syngas (CO+H2) chemistry and hydrogenation of CO2 toward the value‐added aromatic monomers through cascade reactions are highlighted.

“…Efficient conversion of CO 2 is a way to remove the pollutant gas from the atmosphere 1,2 and for the synthesis of fuels, hydrocarbons, and industrially relevant chemicals such as carboxylic acids, esters, lactones, etc. [3][4][5] Cu-Based catalysts have been widely used where one can control the metal-oxide or metal-carbide interfaces (forming the metal and substrates, respectively) to increase the catalyst efficiency. 6 Generally, these processes are energy demanding and are operated at temperatures of about 200-300°C or higher, and at a high pressure of about 50-100 atmospheres.…”

Anthropocene is discussed in this article in the point of view of chemical CO2 capture, use and conversion. The processes and technologies of carbon capture are presented as well as some of the several ways of using or converting it into other chemicals. The technologies of precombustion, poscombustion, oxycombustion and chemical looping were discussed. The materials used for CO2 capture, including amines, solid adsorbents such as charcoal, zeolites, metal organic frameworks, double layer hydroxides and membranes, were briefly presented. The major direct industrial uses of CO2 were discussed for the obtention of key chemicals, such as urea, methanol, cyclic carbonates and carboxylic acids. Some routes were selected to be discussed in more detail, showing the better catalysts and processes in use or research. The comparison between capture and storage and capture and use is not so easy as it may be regarded initially because it depends on the process, technologies, raw materials, obtained products and the analysis of a careful up-todate life cycle (for the present market) of each process and route, which is already not available.
