Carbon Dioxide Hydrogenation

A series of CuO-ZnO-CeO2-ZrO2/HZSM-5 catalysts were prepared and characterized by XRD, H2-TPR. CO2hydrogenation to DME was carried out in a fixed bed reactor to test the catalytic performance of Ce-modified CuO-ZnO-ZrO2/HZSM-5 catalyst under the condition of GHSV=1800 h-1, p=3.0 MPa and T=250°C. The results indicate that the added CeO2improved the performance of the bifunctional catalysts, the CO2conversion and DME selectivity were obviously improved. CuO-ZnO-CeO2-ZrO2/HZSM-5 catalyst with Ce to Zr molar ratio of 1/1 showed the highest activity for DME synthesis from CO2hydrogenation.

AbstractThe current understanding of osteoarthritis is developing from a mechanical disease caused by cartilage wear to a complex biological response involving inflammation, oxidative stress and other aspects. Nanoparticles are widely used in drug delivery due to its good stability in vivo and cell uptake efficiency. In addition to the above advantages, metal/metal oxide NPs, such as cerium oxide and manganese dioxide, can also simulate the activity of antioxidant enzymes and catalyze the degradation of superoxide anions and hydrogen peroxide. Degrading of metal/metal oxide nanoparticles releases metal ions, which may slow down the progression of osteoarthritis by inhibiting inflammation, promoting cartilage repair and inhibiting cartilage ossification. In present review, we focused on recent research works concerning osteoarthritis treating with metal/metal oxide nanoparticles, and introduced some potential nanoparticles that may have therapeutic effects.
