An Unusual State of Gold and Platinum on some Fluoride Supports

Cerium fluoride supported V2O5 catalysts: physico-chemical characterization and 3-picoline ammoxidation activity

“…Sichkar et al [15] have found that CeF 3 is a better support for Pd in hydrogenation of 1-heptene than NaF, CaF 2 , MgF 2 , BaF 2 and AlF 3 , etc. CeF 3 was also used as a support for preparing highly dispersed Au catalysts with Au particle size <10 nm for oxidation reactions [16]. As it is evident from the literature that the fluoride supported V 2 O 5 catalysts are active and selective for the ammoxidation reactions [17][18][19][20], CeF 3 has judicially been selected as the support for the V 2 O 5 catalysts for the ammoxidation of 3-picoline.…”

“…Results of our recent study [9] on the CeO 2 as a catalyst for ammoxidation of picolines and the documented literature [13][14][15][16][17][18][19][20] have prompted us to explore whether CeF 3 can be used as a novel support for vanadia catalysts and further investigate their physico-chemical characteristics and ammoxidation activity for 3-picoline.…”
