“…The endothermic peak at the temperature of 180 °C indicates the removal of physically adsorbed water from catalyst material, and the second endothermic peak at the higher temperature represents dehydroxylation which is also revealed by TGA. 14 DSC and TGA curves became stable after the temperature of 330 °C which shows the stability of the catalyst at high temperatures.…”

“…Catalyst calcined for 5 h (Figure 3c) has shown the bands at 1212, 1126, and 1031 cm −1 , confirming the SO and S−O symmetric and asymmetric vibrations, which are assigned for the chelating sulfate ions that are coordinated to the iron cation (Fe 3+ ). 14 These asymmetrical bands are due to the presence of free sulfate ions on the surface of the catalyst which has further resulted in the leaching of these ions in the reaction mixture. On the contrary, catalyst calcined for 7 h (Figure 3b) has shown the only explainable characteristic band at a subsequent wavenumber of 1128 cm −1 which indicates the presence of significant sulfate ions with Td symmetry.…”

“…9 For example, Shi had reported that the catalytic activities of sulfatepromoted iron oxide dropped from 84.48% to 51.48% aer 10 recycles in the n-butyl acetate esterication. 27 In fact, deactivation is a general problem and a rather complicated phenomenon in heterogeneous catalysis, which is also the main problem faced by SO / ZnAl 2 O 4 -4 wt% Ce solid acid catalyst showed the obviously better reusability, which remained above 80% esterication even aer being used for six times. This result might be attribute to its excellent structural stability and excellent resistance to the loss of the sulfur species.…”
