Carbon Dioxide (CO 2) . Photosynthesis is the process which involves a chemical reaction between water and carbon dioxide (CO 2) in the presence of light to make food (sugars) for plants, and as a by-product, releases oxygen in the atmosphere.Carbon dioxide currently comprises 0.04 percent (400 parts per million) of the atmospheric volume.

  • Coverage Effect of the CO2 Adsorption Mechanisms on CeO2

    The adsorption of carbon dioxide on CeO2(111) has been studied using density functional theory. At low coverage (1/9 monolayer), CO2 is found to preferably adsorb in a monodentate configuration forming a carbonate species with a surface O atom. In this configuration, the CO2 molecule is bent with an O–C–O angle of 129& and a remarkable elongation (to 1.27 Å) of the C–O bond length
