The ethylbenzene dehydrogenation and the oxidation ability of CO2 on the V2O5(001) surface are systematically studied by the density functional theory method. Results show that among all three lattice oxygen sites on V2O5(001): the vanadyl oxygen O(1), the bridge oxygen O(2), and the three-coordinate oxygen O(3), the O(1) site is the active site for the ethylbenzene dehydrogenation. With the production of styrene, the lattice oxygen O(1) is removed by H2O release. As a soft oxidant, CO2 cannot re-oxidize the defected V2O5(001) in time due to the relatively high activation energy, which gradually leads to the deactivation of the catalyst. © 2015 Elsevier Ltd.

This review summarizes how the carbon cycle occurs and how to reduce CO2 emissions in highly efficient carbon utilization from the most abundant carbon source, coal. Nowadays, more and more attention has been paid to CO2 emissions and its myriad of sources. Much research has been undertaken on fossil energy and renewable energy and current existing problems, challenges and opportunities in controlling and reducing CO2 emission with technologies of CO2 capture, utilization, and storage. The coal chemical industry is a crucial area in the (CO2 value chain) Carbon Cycle. The realization of clean and effective conversion of coal resources, improving the utilization and efficiency of resources, whilst reducing CO2 emissions is a key area for further development and investigation by the coal chemical industry. Under a weak carbon mitigation policy, the value and price of products from coal conversion are suggested in the carbon cycle. This journal is © The Royal Society of Chemistry.
