The increase in energy demand caused by industrialization leads to abundant CO 2 emissions into atmosphere and induces abrupt rise in earth temperature. It is vital to acquire relatively simple and cost-effective technologies to separate CO 2 from the flue gas and reduce its environmental impact. Solid adsorption is now considered an economic and least interfering way to capture CO 2 , in that it can accomplish the goal of small energy penalty and few modifications to power plants. In this regard, we attempt to review the CO 2 adsorption performances of several types of solid adsorbents, including zeolites, clays, activated carbons, alkali metal oxides and carbonates, silica materials, metal-organic frameworks, covalent organic frameworks, and polymerized high internal phase emulsions. These solid adsorbents have been assessed in their CO 2 adsorption capacities along with other important parameters including adsorption kinetics, effect of water, recycling stability and regenerability. In particular, the superior properties of adsorbents enhanced by impregnating or grafting amine groups have been discussed for developing applicable candidates for industrial CO 2 capture.

BACKGROUND Rhizosphere soil microbial communities play an important role in grapevine growth. However, the relationship of the rhizosphere soil bacterial community and berry quality of Hutai No.8 grape with different tree‐ages is unclear. In this work, the Biolog‐ECO technique was used to explore the functional diversity of the rhizosphere soil bacterial communities of Hutai No.8 grape with five ages (3, 5, 7, 9 and 11 years old). Meanwhile, grape berry quality indicators related to berry appearance, flavor and functional substance quality was also examined. RESULTS Principal component analysis of grape berry quality mainly separated 3‐year‐old (first bear fruit) and the other tree‐ages. In particular, peel weight and total soluble solid content of 3‐year‐old grape berry was significantly less than that of others. Furthermore, average well color development, species richness and Shannon's diversity index increased significantly with grapevine age. Moreover, the metabolic activities and functional diversity of soil microbial communities in using carbon sources were significantly increasing with grapevine age. Moreover, there were significant correlation between physicochemical indices of grape berry quality and six functional categories of carbon sources. CONCLUSION Tree‐ages could greatly affect the rhizosphere microbial community structure and richness, and then affect the grape berry quality. © 2019 Society of Chemical Industry
