“…These results demonstrate that the carbon presence influences the crystallization process of the ZSM-5 structure. Similar behavior has been found by other researchers 16,21 . It is important to notice that the SiO 2 /Al 2 O 3 ratio of the conventional ZP sample was 31.5 and remained practically unchanged for samples synthesized in the presence of different amounts of carbon particles (Table 1).…”

“…In addition, all the ZSM-5 samples maintained high values of the BET area, total porous volume and mesopores volume after the impregnation with iron. The values of specific surface area (BET) and pore volume obtained in this work are similar to those ones published by others researchers 18,21,34 , using carbon nanoparticles as mesopores template for the ZSM-5 synthesis. Figure 7 shows SEM images of samples ZP-Fe (Figure 7a), ZC4-Fe (Figure 7b), ZC5-Fe (Figure 7c) and the distribution of Fe 2 O 3 particles on the ZC5-Fe sample ( Figure 7d).…”

“…Due to this fact, the preparation of mesoporous ZSM-5 zeolites has attracted a great interest in the catalytic applications [13][14][15] . Among the several methods showed in the literature to produce mesoporous zeolites [16][17][18][19] , the carbon-templating method has demonstrated to be relatively facile and inexpensive, being that after burning of the carbon particles, zeolite crystals with intracrystalline mesoporous are obtained 16,20,21 . However, works reporting the preparation of mesoporous Fe 2 O 3 -supported ZSM-5 zeolites employing a nucleating gel and carbon particles as mesopores template in the synthesis procedure for application as photo-Fenton catalyst under visible light has not been reported yet.…”

Mesoporous Fe 2 O 3 -supported ZSM-5 zeolites were prepared by carbon-templating and subsequently evaluated as photo-Fenton catalysts to degrade a dye used as a model heavy organic pollutant. The synthesis procedure of the mesoporous ZSM-5 zeolites was performed employing a nucleating gel and carbon particles as mesopores template. Thereafter, the precursor salt of the iron oxide (Fe 2 O 3 ) was impregnated and then calcined to obtain the final catalyst. For comparison purposes, a conventional Fe 2 O 3 -supported ZSM-5 zeolite was also prepared. The results showed that the amount of intracrystalline mesopores formed in the ZSM-5 crystals was influenced by the amount of carbon added into the synthesis mixture. In comparison to the conventional prepared catalyst, the mesoporous Fe 2 O 3 /ZSM-5 ones showed an improved performance in the degradation of the target organic pollutant by the photo-Fenton reaction, which was attributed to the improvement of their textural properties as consequence of the mesopores generation.

“…Microwave 38,39 or ultrasound-assisted syntheses 42 and dry gel conversion methods 47 are the most prominent of them. Figure 2 shows the relative crystallinity of 0.5% SZ/MIL-101 with different times in the syntheses using conventional electric and microwave (MW) methods.…”

A porous metal-organic framework (MOF), MIL-101, was synthesized in the presence of sulfated zirconia (SZ) to produce acidic SZ/MIL-101 composites for the first time. The composites were characterized with XRD, nitrogen adsorption, FT-IR, scanning electron microscope, chemical analysis and so on. The composites (SZ/ MIL-101s) were successfully applied in a liquid-phase esterification for a high yield of ester. This catalytic result of SZ/MIL-101, compared with that of pure SZ or MIL-101 (showing a negligible yield of ester), suggests that the SZ in the composite is highly active in the acid catalysis probably because of the welldispersed active species of SZ. Moreover, the esterification is catalyzed in heterogeneous mode as confirmed by negligible esterification after filtration of the catalyst. Finally, microwaves can be efficiently applied both in the synthesis of the composites and the esterification reaction to accelerate the two processes of synthesis and esterification by about 5 times.
