“…10,13 As reported in previous research, the CO 2 concentration present in the air (0.038%) may limit microalgal growth, 14 and supplementing the cultures with an additional carbon source may be an alternative to increase the biomass production. However, when high CO 2 concentrations are supplied continuously to the cultures, they can cause a reduction in the pH and thus a reduction in the culture growth rates. 1,15,16 For that reason, it is necessary to evaluate this variable to allow for the mass production of microalgae and biomass with a high content of biomolecules.…”

The aim of this study was to evaluate the influence of different carbon dioxide (CO2) concentrations on the distribution of carbon forms in the culture medium and the biomass production and biomolecules productivity of the strain Chlorella fusca LEB 111. In this study, experiments were carried out in which C. fusca cultures were exposed to different CO2 concentrations, 0.03% (0.08 mlCO2 mlmedium−1 days−1), 5% (0.18 mlCO2 mlmedium−1 days−1), and 15% vol/vol CO2 (0.54 mlCO2 mlmedium−1 days−1). Among the carbon chemical species distributions in the culture medium, bicarbonate was predominant (94.2–98.9%), with the highest quantitative percentage in the experiment receiving a 15% CO2 injection. C. fusca LEB 111 cultivated with 15% CO2 showed the highest biomass productivity (194.3 mg L−1 days−1) and CO2 fixation rate (390.9 mg L−1 days−1). The carbohydrate productivity in the culture that received 15% CO2 was 46.2% higher than the value verified for the culture with the addition of CO2 from the air (0.03% CO2). In addition, CO2 concentration providing increases of 0.03–15% to C. fusca cultures resulted in a 31.6% increase in the lipid productivity. These results showed that C. fusca can be used for CO2 bioconversion and for producing biomass with potential applications for biofuels and bioproducts.

Emerging Trends in Sustainable CO₂‐Management Materials

increased frequency of weather extremes and related energy and environmental issues affecting all living species on the planet. As a result, a CO 2 -management scheme has been stimulated and proposed. To begin with, the development and deployment of carbon capture technologies has been widely acknowledged as a strong imperative for decarbonizing industry and promoting net CO 2 removal from the atmosphere. [4,5] Following the carbon capture, the conventional storage process, however, is unprofitable per se that requires large capital investment, heavily hindering its applicability in the commercial sector; meanwhile, more issues remain in the safety of underground and ocean CO 2 storage, while the potential locations are still under survey and assessment. A promising alternative to storage is the purposeful utilization of CO 2 as a renewable feedstock for producing high-value-added chemicals and fuels, which could not only curb carbon emissions but also provide a revenue stream that offsets capture costs and may even create positive cash flow. The conversion of CO 2 to chemicals and energy products using renewable resources such as solar, wind, and tide not only enables the storage of intermittent renewable energy in chemical bonds for easy transportation and efficient utilization, but also fulfills a transition from a liner carbon economy to a circular carbon-neutral economy for energy sustainability (Figure 1). [6,7] Recent years have witnessed the great progress in the realm of sustainable CO 2 -management materials, especially centering on CO 2 capture, utilization, and catalytic conversion, contributing to a promising and potent solution to both emissioncontrol and energy-supply challenges. However, there is a lack of a timely review on the state-of-the-art advances of holistic CO 2 -management technologies from the material perspective. The purpose of this review is to provide a critical and complete overview of the main and emerging development of promising materials for sustainable CO 2 management. We give in-depth analyses of CO 2 capture, catalytic conversion, and direct use at numerous scales of material research, ranging from mechanism comprehension through targeted design and fabrication, property manipulation, to industrial implementation. Meanwhile, strategic considerations for both liquid and solid CO 2 capturing materials under various operational conditions as With the rising level of atmospheric CO 2 worsening climate change, a promising global movement toward carbon neutrality is forming. Sustainable CO 2 management based on carbon capture and utilization (CCU) has garnered considerable interest due to its critical role in resolving emission-control and energy-supply challenges. Here, a comprehensive review is presented that summarizes the state-of-the-art progress in developing promising materials for sustainable CO 2 management in terms of not only capture, catalytic conversion (thermochemistry, electrochemistry, photochemistry, and possible combinations), and direct utilization, but also eme...

Reducing CO2 emissions is an urgent global priority. In this context, several mitigation strategies, including CO2 tax and stringent legislation, have been adopted to halt the deterioration of the natural environment. Also, carbon recycling procedures undoubtedly help reduce net emissions into the atmosphere, enhancing sustainability. Utilizing Earth’s abundant CO2 for the production of high‐value chemicals and fuels opens new avenues for the chemical industry. In this context, much effort has been devoted to converting CO2 as a feedstock into various value‐added chemicals, such as CH4, lower olefins, methanol, gasoline, and long‐chain hydrocarbons, for numerous applications involving various catalytic reactions. Although several CO2‐conversion methods have been used, including electrochemical, photochemical, and biological approaches, the hydrogenation method allows the reaction to be tuned to produce the targeted compound without significantly altering infrastructure. This review discusses the numerous hydrogenation routes and their challenges, such as catalyst design, operation, and the combined art of structure–activity relationships for the various product formations.
