| 摘 要： | A new catalyst for methanol synthesis,ZnO-promoted rhodium supported on carbon nanotubes,was developed.It was found that the Rh-ZnO/CNTs catalyst had high activity of 411.4mg CH3OH/g/cat/h and selectivity of 96.7% for methanol at 1 MPa and 523 K.The activity of this catalyst is much higher than that of NC 207 catalyst at the same reaction conditions.It was suggested that the multi-walled strueture CNTs favored both the couple transfer of the proton and clectron over the surface of the catalyst and the uptake of hydrogen which was favorable to methanol synthesis.

| Abstract: | A new catalyst for methanol synthesis, ZnO-promoted rhodium supported on carbon nanotubes, was developed. It was found that the Rh-ZnO/CNTs catalyst had high activity of 411.4 mg CH3OH/g/cat/h and selectivity of 96.7 % for methanol at 1 MPa and 523 K. The activity of this catalyst is much higher than that of NC 207 catalyst at the same reaction conditions. It was suggested that the multi-walled structure CNTs favored both the couple transfer of the proton and electron over the surface of the catalyst and the uptake of hydrogen which was favorable to methanol synthesis. |
