Abstract

The incorporation of molybdenum into the faujasite pore system via reaction of MoCl5 with H-Y zeolite results in dealumination of the zeolite framework and formation of MoO3 species. These species are readily sulfided by H2S, but MoS2 clusters are not produced. A sulfur-bridged dimeric molybdenum cluster, of proposed composition HO-Mo-(S)3-Mo-OH, is formed, which can strongly chemisorb CO. Sulfidation of niobium in this manner is not readily accomplished.
