“…As a catalyst, functionalized biochar containing sulfonic acid groups (SO 3 H) has shown favorable performance in the hydrolysis of biomass, biodiesel production, and in various acid‐catalyzed reactions (e. g. acylation of alcohols and amines, and alkylation of aromatics) . In cycloaddition reactions, other groups have demonstrated the use of carbon‐based materials containing oxygenated groups on their surface as catalysts . Therefore, the presence of carboxyl groups on the surface of the oxidized biochar inspired us to investigate its activity towards CO 2 ‐epoxide coupling reactions.…”

Hard‐ and softwood residues (from birch and pine respectively) of forestry, pulp, and paper industries (e. g. sawdust, branches) were used to prepare biochar, which was then oxidized using nitric acid to produce catalytic carboxylic acid functionalized biochar. This oxidized biochar, ox–bc, in the presence of a co‐catalyst, showed excellent catalytic activity towards the cycloaddition reaction between CO2 and epoxides using mild conditions (CO2 pressure, 10 bar). No differences in catalytic activity were seen between the two types of oxidized biochar despite the hardwood ox–bc having a significantly higher surface area. The catalysts function through activation of the epoxide reagent via hydrogen‐bonding with carboxylic acid groups on the surface. The number of surface acid groups was reduced by reaction with 3‐aminopropyltriethoxysilane and the resulting material was inactive in the reactions studied. The ox–bc catalysts are sustainable, economic, and renewable alternatives for currently used heterogeneous systems and are also the first carbon‐based materials derived from biomass to exhibit good recyclability (over five runs) with a broad substrate scope for the production of cyclic carbonates from epoxides and CO2.

“…The selectivity in the production of cyclic carbonates can be further improved by the use of nanotechnologies and several nanostructured materials. Graphene oxide together with an appropriate cocatalyst was found to have high yields and reaction rates in relatively mild conditions [78,79]. Also, nanoparticles of crosslinked polymers with basic functionalities were found to improve the cyclization reaction [80][81][82].…”

It is not the first time in human history, nor will it be the last for that matter, that a collective problem calls for a collective response. Climate change fueled by greenhouse emissions affects humankind alike. Despite the disagreement among policymakers and scientists on the severity of the issue, the truth is that the problem remains. A broad look at different technologies being used today in different fields has led to the idea of bringing them together in an attempt to offer a viable solution to reducing anthropogenic CO 2 . The following paper describes how the nanotechnologies, available or soon to be available, would make CO 2 capture, cache, and conversion (coined the three Cs) a valid way for achieving a more sustainable energy society. Authors also set out to highlight with this work how knowledge transfer is instrumental in the development of technology and how methodical assessment of crossovers can expedite research when time plays against us.

“…Yin et al [79,[122][123] also did a sequence of studies in preparing GO based SILs to catalyze the CO 2 fixation into cyclic carbonates. GO functionalized with quaternary ammonium ILs (denoted as MF-GO) was prepared by covalent grafting method as shown in Figure 12D.…”
