“…3,4 For example, Al 2 O 3 does not reveal any catalytic activity due to not decomposing ozone according to some research, 5,6 while others report Al 2 O 3 is an active catalyst due to the adsorption of organic compounds and ozone on its surface. 7,8 Also, there are four different hypotheses for the adsorption and decomposition of ozone on Fe-hydroxyoxides. 9 In addition, in most of the literature, 10,11 the high efficiency of catalytic ozonation was assigned to the hypothesis of hydroxyl radicals (…”

Fe 2 O 3 and/or Al 2 O 3 were supported on mesoporous SBA-15 by wet impregnation and calcinations with AlCl 3 and FeCl 3 as the metal precursor and were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectra (FTIR) of adsorbed pyridine. Fe 2 O 3 /Al 2 O 3 @SBA-15 was found to be highly effective for the mineralization of ibuprofen aqueous solution with ozone. The characterization studies showed that Al−O−Si was formed by the substitution of Al 3+

“…Radwan et al [4] revealed solid-solid interaction between Fe 2 O 3 and Co 3 O 4 takes place at temperatures higher than 700°C to produce CoFe 2 O 4 . CoAl 2 O 4 has been applied in some catalytic reaction [5][6][7]. Nevertheless, most of the reports have been focused on the magnetic behavior of CoFe 2 O 4 nanoparticles [8].…”

A series of Co-AT (attapulgite) catalysts were prepared by wetness impregnation method. Detailed characterization indicated that there indeed exists interaction between Co and the support AT, leading to the formation of spinel of CoAl 2 O 4 and CoFe 2 O 4 . Al and Fe species of AT promote the formation of CoFe 2 O 4 spinel with much lower temperature (400°C). The catalytic behavior was investigated by the liquid-phase solvent-free oxidation of cyclohexane and Co-AT-1 shown better activity than CoFe 2 O 4 and Co 3 O 4 , which was likely due to a cooperation effect between CoFe 2 O 4 and Co 3 O 4 .
