摘要：

Mechanically mixed Ga2O3/HZSM-5 catalysts have been examined via X.p.s. and X-ray diffraction both before and after reduction with H-2. Results are consistent with the postulate that there is a strong interaction of Ga2O3 With HZSM-5, which results in a transfer of Ga into the zeolite upon reduction.
