“…P-OH groups are most probably responsible for Bronsted acidity on AlPO 4 surfaces and are quite stable. 39,40 In addition, P-OH acidity may be further enhanced by hydrogen bonding to Al-OH groups, as stated by Moffat et al 41 However, the acid properties of AlPO 4 can be modied by introducing elements different from Al and P in the framework at different loading. Thus, it is evident from Fig.…”

“…The current composite catalysts' catalytic performance was examined for the Vapor phase dehydration of isopropanol employing chromatographic analysis by FID with a Unicam Pro GC2000 [12,22,47]. In a typical experiment 300 mg using of catalyst, in the temperature range120-250 o C, air atmosphere as a carrier gas, and the total flow rate was 50 ml min -1 , 2.7 % isopropanol (IPA) in the gas feed and space-time (GHSV 10,000mlg -1 h -1 ).…”

Cerium iron mixed oxide (CFO) nanocomposite materials supported on spherical silica particles were explored for gas phase dehydration of isopropyl alcohol (IPA). The samples were formed by a sol-gel process. Utilization of silica as a matrix for reducible CeO2-Fe2O3 mixed oxides formation of thermally stabilized textural CeO2-Fe2O3 /silica nanocomposite materials, Thus, a series of 10-30% (w/w) CFO/silica was directly formed, dried, and calcined at 550 o C. XRD, TG-DTA, ATR-FTIR, nitrogen adsorption−desorption, and TEM images were used to analyze the samples. The catalytic performance of materials has been estimated. The catalytic activity of the catalytic materials was evaluated to measure the dehydration reaction of IPA at 250 o C in the air atmosphere. According to the results, 20% CeFeO3/silica calcined at 550 o C exhibits a high conversion of IPA amounts to ~89% with selectivity (100%) for propene, as well as a high rate of propene production (7.9 m mol.h -1 ). The higher catalytic activity of the supported catalyst was related to its improved textural and thermal stability, based on these results, propene is efficiently produced.

A series of AIPO 4 -MoO 3 (APM) systems with various molybdena loadings (5-50) mol %, same modified with phosphomolybdic acid (PMA) and cerium ions, were prepared by an impregnation method and calcined at 400• C, except for the samples modified with PMA which were calcined at 350• C for 4 h. The catalysts were characterized by TG/DTG, XRD, IR spectroscopy, N 2 adsorption and electrical conductivity measurements. The surface acidity and basicity of the catalysts were determined by adsorption of pyridine and the dehydration-dehydrogenation of isopropyl alcohol. The catalytic esterification of acetic acid with ethanol was carried out in a convention fixed bed reactor. The results clearly revealed that the catalyst with a composition of 10 mol % MoO 3 (APM10) was the most active and selective catalyst for the production of ethyl acetate. Moreover, the yield of ethyl acetate increases on addition of PMA into APM10 while it decreases on the addition of Ce 4+ ions. These results were correlated with structure, semiconductivity and the acid-base properties of the prepared catalysts.
