Good electrical conductivity and high electron mobility of the sorbent materials are prerequisite for electrocatalytically switchable CO2 capture. However, no conductive and easily synthetic sorbent materials are available until now. Here, we examined the possibility of conductive graphitic carbon nitride (g-C4N3) nanosheets as sorbent materials for electrocatalytically switchable CO2 capture. ...

the precipitation of calcium carbonate by bacteria isolated from submerged fixed-film bioreactorused for the treatment of urban wastewater in both natural and artificial media was studied. however, carbonate precipitation was detected only when the bacteria grow in media added with calcium. precipitation took place rapidly, and crystal formation began 3 d after inoculation and the percentage of...

*Correspondence: Yuhan Sun, Shanghai Advanced Research Institute, Chinese Academy of Sciences, 100 Haike Road, Zhangjiang, Pudong, Shanghai 201203, China e-mail: [email protected] CO2 capture represents the key technology for CO2 reduction within the framework of CO2 capture, utilization, and storage (CCUS). In fact, the implementation of CO2 capture extends far beyond CCUS since it will link th...

We have conducted a detailed analysis of costs associated with today’s technology for CO2 separation and capture at three types of power plants: integrated coal gasification combined cycles (IGCC), pulverized coal-fired simple cycles (PC), and natural gas-fired combined cycles (NGCC). The analysis was based on studies from the literature that analyzed the economics of capturing CO2 emitted at p...

Materials and processes for CO2 capture and utilisation are an essential part of a holistic approach toward a sustainable energy future. CO2 and energy are tightly intertwined as energy produced from fossil fuel combustion always generates CO2. A major environmental concern, CO2 could also become an invaluable resource for making carbon-based materials and chemicals, and a means to store energy...

Carbon dioxide capture process has been simulated and studied under different process conditions. It has been shown that several process parameters such as lean amine temperature, number of adsorber stages, number of stripper stages and stripper pressure affect different process conditions and outputs such as carbon dioxide removal and reboiler duty. It may be concluded that the simulation of c...

Different alkylamine molecules were post-synthetically tethered to the unsaturated Cr(III) centers in the metal-organic framework MIL-101. The resultant metal-organic frameworks show almost no N2 adsorption with significantly enhanced CO2 capture under ambient conditions as a result of the interaction between amine groups and CO2 molecules. Given the extraordinary stability, high CO2 uptake, ul...
