“…Over the last decades, the use of Bronsted acid catalysts has been increased in both laboratories and industries processes, such as biodiesel production, esterification and hydrolysis because of liquid phase limitations, hard separation, non-recovery acidic waste generation and the corrosion of reactors [ 1 , 2 , 3 , 4 ]. Nano-substrates with a larger surface area and high surface-to-volume ratio have been applied in the solid acid catalysis field to increase available catalytic centers and enhance catalytic activity [ 5 , 6 ].…”

Over the past several decades, the fabrication of novel ceramic nanofibers applicable in different areas has been a frequent focus of scientists around the world. Aiming to introduce novel ceramic core-shell nanofibers as a magnetic solid acid catalyst, Fe 2 O 3 @SiO 2 –SO 3 H magnetic nanofibers were prepared in this study using a modification of Fe 2 O 3 @SiO 2 core-shell nanofibers with chlorosulfonic acid to increase the acidic properties of these ceramic nanofibers. The products were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), energy dispersive X-ray spectroscope (EDS), vibrating sample magnetometer (VSM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The prepared nanofibers were used as catalysts in formamide and formamidine synthesis. The treatment of aqueous formic acid using diverse amines with a catalytic amount of Fe 2 O 3 @SiO 2 –SO 3 H nanofibers as a reusable, magnetic and heterogeneous catalyst produced high yields of corresponding formamides at room temperature. Likewise, the reaction of diverse amines with triethyl orthoformate led to the synthesis of formamidine derivatives in excellent yields using this novel catalyst. The catalytic system was able to be recovered and reused at least five times without any catalytic activity loss. Thus, novel core-shell nanofibers can act as efficient solid acid catalysts in different organic reactions capable of being reused several times due to their easy separation by applying magnet.

“…About 10 mg of catalyst was placed in an alumina crucible and heated from 30 °C to 550 °C under air (20 ml/min). The FTIR analysis was performed with a Nicolet iS10 FTIR with 8 cm -1 spectral resolution at room temperature and an accumulation of 5 scans in open beam air background [16]. The spectrum ranged from 4000 cm -1 to 400 cm -1 .…”

Platinum (Pt), a noble metal, is known for its ability to regenerate and be recycled even without any reactivation procedure, and still demonstrated good stability. The cost of the noble metal can be reduced by incorporating the metal into the pores of catalyst support rather than using it individually. Hence, in this research study, 4 wt.% Pt supported on silica-alumina (SiO2-Al2O3) and gamma-alumina (γ-Al2O3) was synthesized using wet impregnation method, then followed by catalyst calcination at 500 °C. The catalyst was then characterized using Thermogravimetric Analysis (TGA), Fourier-Transform Infrared Spectroscopy (FTIR), Brunauer–Emmett–Teller (BET), and particle size analyzer where catalyst with high surface area and pore volume demonstrated an excellent performance for the catalytic reaction of cellulose. Experimental results showed that catalyst Pt/SiO2-Al2O3 with the highest surface area and pore volume (466.4 m2/g and 0.1157 cm3/g, respectively) exhibited the highest catalytic performance with the conversion of cellulose up to 65.8% and 30.9% levulinic acid (LA) yield produced at the reaction temperature of 200 °C in a semi-batch reactor for 8 hrs.
