Supported Cu catalysts with yttria-doped ceria for steam reforming of methanol
作者： Wu-Hsun Cheng
关键词:
摘要: The steam reforming of methanol was studied over Cu/Al 2 O 3 catalysts with the addition of yttria-doped ceria (YDC). The YDC-modified catalysts were prepared by impregnating a γ-Al 2 O 3 support with Y and Ce then with Cu. The addition of YDC drastically enhanced the activity of Cu/Al 2 O 3 in the methanol reforming reaction. The enhanced activity was attributed to the increase of Cu+ species by YDC in the methanol reforming environment. However, the addition of YDC decreased the copper dispersion. The Cu dispersion could be …
