Dry reforming of methane with CO2 over ordered mesoporous Ni/SBA-15@SiO2 |
| 초록 |
Dry reforming of methane (DRM) reaction is useful one because it converts the main two greenhouse gases into the industrial materials by using Ni-based catalysts with a comparable catalytic activity. However, Ni-based catalysts revealed the sintering and coke deposition natures due to its thermal instability at high temperature. To overcome the limitations, an overlayer coating method of Ni nanoparticles by using silica shell was applied with highly ordered mesoporous silica support (SBA-15). The overlayer coating method increased anti-sintering natures of Ni nanoparticles. With the positive contributions of spatial confinement effects of the ordered mesoporous SBA-15, and the improved catalytic activity and thermal stability of Ni nanoparticles during DRM reaction were observed with the preservation of original Ni sizes, which were confirmed by the characterization of XRF, XRD, TEM, TGA and so on. |
