“…As reported by Helmi et al (2021), phosphomolybdic acid was supported on clinoptilolite-Fe 3 O 4 , and the prepared catalyst showed excellent activity (80% yield in 8 h at 75 °C) and reusability in the production of biodiesel from Salvia mirzayanii oil. The HPA/clinoptilolite-Fe 3 O 4 catalyst was able to recycle up to four times with minimal loss in activity.…”

In this study, we summarize recent advances in the synthesis of magnetic catalysts utilized for biodiesel production, particularly focusing on the physicochemical properties, activity, and reusability of magnetic mixed metal oxides, supported magnetic catalysts, ionic acid-functionalized magnetic catalysts, heteropolyacid-based magnetic catalysts, and metal–organic framework-based magnetic catalysts. The prevailing reaction conditions in the production of biodiesel are also discussed. Lastly, the current limitations and challenges for future research needs in the magnetic catalyst field are presented.

“…The peak that emerged at 2340 cm –1 in Figure a(i,ii) is attributed to the atmospheric CO 2 . Also, the peaks at 580 and 630 cm –1 are distinctive peaks for metal–oxygen (Fe–O) stretching vibration modes. , These peaks are characteristically marked for all spinel structures and ferrites. The distinctive ZnO NRs’ functional groups are exhibited in Figure a(ii).…”

This study presents a novel photocatalytic system for photocatalytic degradation of Eriochrome black-T (EBT) dye via green light-emitting diode (LED) light exposure. This photocatalyst is comprised of nanoscale components, i.e., poly-(vinyl alcohol) (PVA), magnetic iron oxide nanoparticles (Fe 3 O 4 NPs), gold NPs (Au NPs), and zinc oxide nanorods (ZnO NRs), rendering an active high surface area. The most highlighted property from the structural facet is the superparamagnetic behavior of Fe 3 O 4 NPs, which provides a facile collection of magnetic photocatalyst NPs from the reaction flask and is successfully recycled eight times without considerable reduction in catalytic behavior. Briefly, the photocatalytic degradation at its highest efficiency reached 51.4% (10 ppm dye solution, 5.0 mL) and 64.75% (8 ppm dye solution, 5.0 mL) utilizing 10 mg of the designed photocatalyst (formulated as Fe 3 O 4 @PVA−Au/ZnO), a magnetic photocatalytic system under green LED light (7 W, 526 nm) exposure for 60 min. Besides, the photocatalytic degradation mechanism of the EBT dye by the as-prepared photocatalyst was proposed. Based on the obtained results, the presented photocatalytic method was recommended for scaling up and large-scale exploitation for the purification of the water resources.

The development of a cost-efficient, highly effective, and granular shape adsorbent is highly desired for nitrate removal. In this study, two different Fe(OH)3 nanoparticles with amorphous and crystalline structures, and nanocomposites were successfully synthesized using the ultrasonic-assisted co-precipitation. Both nanoparticles were scrutinized using FTIR, SEM, and XRD. Crystallized Fe(OH)3/zeolite nanocomposites were not efficient for nitrate removal;hence, the rest of the study was carried out with amorphous Fe(OH)3 nanoparticles (Am-Fe(OH)3). Clinoptilolite and analcime were acid-washed and used as a support for synthesized Am-Fe(OH)3 nanoparticles. Nanocomposites of clinoptilolite and analcime were abbreviated as Fe(OH)3/Clin and Fe(OH)3/Anc, respectively. The nanocomposites were characterized by BET, FTIR, SEM, EDS, and XRD techniques. Subsequently, granules of the above-mentioned nanocomposites were prepared using the wet gelation method and alginate. Two crucial features of pH and adsorbent:alginate ratio, were assessed and optimized as 11-12 and 1:3, respectively. The performance of granules were investigated regarding pH, time, and adsorbent dosage. Fe(OH)3/Clin and Fe(OH)3/Anc granules removed 96.82% and 34.02% of nitrate from a contaminated solution with initial concertation of 50mg/L. Overall, Fe(OH)3/Clin granule was an effective adsorbent for nitrate removal. The maximum adsorption capacity of Fe(OH)3/Anc and Fe(OH)3/Clin were 0.4443 mg/g and 5.6211 mg/g for 0.2 g of each adsorbent, respectively. Both adsorbents displayed good compatibility with the pseudo-second-order kinetic model.
