The process of catalytic conversion of carbon dioxide (CO2) is a crucial area of research in the field of green chemistry. CO2 is a major greenhouse gas and its emission is the primary cause of global warming. Therefore, it is essential to develop efficient and effective methods for converting CO2 into useful products. In this review, we will discuss the recent advances in the catalytic conversion of CO2 by cobalt atomic catalysts in different nitrogen-sulfur coordination environments.

Cobalt-based catalysts have gained a lot of attention in recent years for CO2 conversion due to their unique properties such as high activity, selectivity, and stability. The nitrogen-sulfur coordination environments play a critical role in enhancing the catalytic performance of cobalt-based catalysts. These coordination environments can be achieved by introducing different ligands or additives into the catalyst system.

One of the most promising nitrogen-sulfur coordination environments for cobalt-based catalysts is the incorporation of pyridinic nitrogen and thiophene sulfur. This coordination environment has been shown to enhance the catalytic activity of cobalt-based catalysts for the reduction of CO2 to formate. The pyridinic nitrogen and thiophene sulfur act as active sites for CO2 adsorption and activation, leading to improved catalytic performance.

Another effective nitrogen-sulfur coordination environment for cobalt-based catalysts is the incorporation of imidazole nitrogen and thiol sulfur. This coordination environment has been shown to enhance the selectivity of cobalt-based catalysts for the production of methanol from CO2. The imidazole nitrogen and thiol sulfur act as active sites for the formation of the methanol intermediate, leading to improved selectivity.

In addition, the introduction of other ligands such as amines and phosphines into the cobalt-based catalyst system has also been shown to enhance the catalytic performance for CO2 conversion. These ligands can act as electron donors, leading to improved CO2 activation and conversion.

Overall, the catalytic conversion of CO2 by cobalt-based catalysts in different nitrogen-sulfur coordination environments has shown great promise for the development of efficient and effective methods for CO2 conversion. The incorporation of pyridinic nitrogen and thiophene sulfur, imidazole nitrogen and thiol sulfur, and other ligands has been shown to enhance the catalytic activity and selectivity of cobalt-based catalysts. Further research in this area is needed to optimize the catalytic performance of cobalt-based catalysts for CO2 conversion and to develop practical applications for these catalysts in industry
