- Amine-containing sorbents have been extensively studied for postcombustion carbon dioxide (CO2) capture because of their ability to chemisorb CO2 from the flue gas.
- The growing CO2 concentration in the atmosphere forces researchers to work on improving existing carbon dioxide capture technologies.
- Global warming is a critical issue resulting partly from increasing carbon dioxide emissions.
- Superelastic carbon aerogels have been widely explored by graphitic carbons and soft carbons.
- Glassy carbon is a technologically important material widely used in products such as electrodes and high-temperature crucibles.
- Till date metallocenes, especially ferrocene is the only reliable precursor for microwave synthesis of carbon nanotubes (CNT).
- Supercritical carbon dioxide Brayton power cycle is getting commercially attractive for power generation due to numerous advantages like zero water usage, compactness, low environmental emission, and potential to reach high thermal efficiency at lower costs.
- Granular activated carbon loaded with aniline,o-nitroaniline oro-nitrophenol, regenerated at relatively low temperature (450 in N2 atmosphere), shows losses of cyclic adsorption performances (about 5 % per cycle) comparable to those occurring with standard thermal regeneration (950° in controlled atmosphere).
- Graphitic carbon nitride (g-C3N4), a polymeric semiconductor, has become a rising star for photocatalytic energy conversion because of its facile accessibility, metal-free nature, low cost, and env.
- Because of its rough surface and the hydrophobic property of porous activated carbon (AC) particles, it is more difficult to grow a zeolite layer on an AC surface than on metal oxides.
- Accelerated carbonation is a new technology of materials preparation, which may have potential for the treatment of industrial solid residues and the sequestration of CO2, an important greenhouse gas.
- Carbon dioxide has successfully been used as an alternative refrigerant in many applications, replacing chlorofluoro- and hydrofluorocarbons (CFCs and HFCs), due to its negligible ozone depletion and significantly lower global warming potential.
