    Abstract: As biocatalytic carbon capture has attracted wide attraction due to its high energy efficiency, the preference of carbon species of the reaction is concerned. The self-evolution between carbon species makes the determination of preference a changeling issue. In this study, by comparing the isocitrate dehydrogenase reaction rate profiles with pre-equilibrated and un-equilibrated HCO3--CO2 solutions, gas phase carbon dioxide was believed as the optimum substrate, as it can provide higher reaction rate. During the carbon capture process, the partial pressure of the carbon dioxide affected both the reaction equilibrium and kinetics, while the interfacial area can only determine the reaction rate.

    Immobilization of Isocitrate Dehydrogenase on Mesoporous Silica Foam for Carbon Dioxide Capture

    Abstract: Carbon capture can be realized effectively through isocitrate dehydrogenase reaction and the reaction rate was strongly affected by the environmental parameters such as pH and temperature. Enzyme immobilization was conducted to improve the enzyme stability during the capture process. By simply adsorbing enzyme on the surface of mesoporous silica foam, enzyme stability against temperature, pH and shear stress was improved. The immobilization process can be completed in 5 mins, and 0.87 U enzyme activity was kept for each gram of immobilization material. After 10 cycles, more than 50 percent of enzyme activity remained. The reusability and improved stability made immobilized ICDH a better candidate for large-scale application of carbon capture.

    Impacts of meteorological conditions on PM 2.5 and PM 10 pollution in Zhengzhou, China

    Abstract: Meteorological conditions play an important role in aerosol pollution. In this study, the relationships between wind, temperature, relative humidity, and aerosol concentrations (PM 2.5 and PM 10 ) in Zhengzhou from January 2016 to December 2017 were analysed. Backward trajectory model was also used to investigate the relationship between meteorological parameters and regional transport of pollutants. Significant seasonal variations can be observed in the time series of pollutants and wind, temperature and relative humidity. The simulation of backward trajectories indicated that pollutants from southeast is critical to the air quality in Zhengzhou, in addition to local emissions of pollutants. To improve the air quality in Zhengzhou, joint efforts to reduce emissions in both Zhengzhou and its southeast adjacent regions should be considered.
