“…This reaction setup was also tested with propionitrile, butyronitrile, benzyl chloride and toluene in the anolyte compartment. Adjacent functional groups weaken C–H bonds, yielding relatively stable radicals, in turn resulting in selective CO 2 fixation [ 150 ].…”

SummaryThe near-unlimited availability of CO2 has stimulated a growing research effort in creating value-added products from this greenhouse gas. This paper presents the trends on the most important methods used in the electrochemical synthesis of carboxylic acids from carbon dioxide. An overview is given of different substrate groups which form carboxylic acids upon CO2 fixation, including mechanistic considerations. While most work focuses on the electrocarboxylation of substrates with sacrificial anodes, this review considers the possibilities and challenges of implementing other synthetic methodologies. In view of potential industrial application, the choice of reactor setup, electrode type and reaction pathway has a large influence on the sustainability and efficiency of the process.

“…Therefore, they constitute most promising carbon-based energy vectors derived from this value-added carbon management technology. As the electrochemical method offers several advantages 101 over thermochemical routes a great variety of organic compounds such as benzylchlorides, 182,183 alkenes, 184 alkynes and epoxides, 185,186 have been successfully synthesized by electrochemical routes.…”

This review summarizes how the carbon cycle occurs and how to reduce CO2 emissions in highly efficient carbon utilization from the most abundant carbon source, coal. Nowadays, more and more attention has been paid to CO2 emissions and its myriad of sources. Much research has been undertaken on fossil energy and renewable energy and current existing problems, challenges and opportunities in controlling and reducing CO2 emission with technologies of CO2 capture, utilization, and storage. The coal chemical industry is a crucial area in the (CO2 value chain) Carbon Cycle. The realization of clean and effective conversion of coal resources, improving the utilization and efficiency of resources, whilst reducing CO2 emissions is a key area for further development and investigation by the coal chemical industry. Under a weak carbon mitigation policy, the value and price of products from coal conversion are suggested in the carbon cycle.

“…It should be noted that reduction of CO 2 to formate was the main process observed if the nickel catalyst was omitted and only the ruthenium complex was used [11]. Closely related systems have been exploited also for photoreduction processes on substrates different from CO 2 , such as the reductive dehalogenation of organic halides [22].…”

Ruthenium tris-bipyridine derived complexes functionalized by either carboxyl or phosphonyl groups were tested as sensitizers for the photocatalytic reduction of carbon dioxide in the presence of nickel cyclam acting as a catalyst, and a sacrificial donor. These systems were shown to be as efficient as the unsubstituted compounds in solution. Covalent binding to titania nanoparticles gave slightly different results from those with the untreated semiconductor.
