Biobased aromatics offer a promising opportunity to replace fossil-based chemical building blocks, thereby supporting the achievement of the UN Sustainable Development Goals (SDGs). This study explores the conversion of Sapium oil (tree-borne seed oil) to aromatic-rich hydrocarbons as a viable alternative for producing renewable petrochemicals. The catalytic transformation of Sapium oil to C6–C8 aromatics over a pelletized Ga-AlPO4/Y catalyst (50–70 mesh) was studied in a fixed-bed continuous flow reactor. The highest Sapium oil conversion of 93.8% was obtained, with 86.2% aromatics at 480 °C under atmospheric pressure. Benzene, toluene, ethylbenzene, and xylene (BTEX) were the significant aromatics formed (about 54.3% of the total product), and a total BTX production of 3.2 g g–1 catalyst was achieved within a catalyst lifetime of >4 h per cycle. The addition of Ga remarkably promoted the aromatic yield compared to pure Y zeolite or AlPO4. The catalyst deactivation model was described by an exponential function of time-on-stream with temperature, followed by the frequency factors and activation energies being calculated using the Arrhenius equation. The activation energy for catalyst deactivation (E α) was 24.30 kJ mol–1 and the frequency factor (α0) was 13.97. These results provide valuable insights into the catalytic process and its stability over time. The triglyceride-rich Sapium oil is expected to serve as key feedstock for low-carbon technologies in the future production of aromatic biobased chemicals.

“…The Si 2p spectral region of the sample presented in Figure a consists of five peaks at binding energies of 100.5, 101.4, 102.2, 103.1, and 104.3 eV assigned to Si + (Si 2 O), Si 2+ (SiO), Si 3+ (Si 2 O 3 ), Si 4+ (SiO 2 ), and Si 4+ (SiO 2 ) species, respectively. , The Al 2p spectrum is deconvoluted into four different peaks, as shown in Figure b. The main peak at a binding energy of 74.2 eV is attributed to the appearance of Al 3+ (Al 2 O 3 ) species in the sample. , In Figure c, the O 1s XPS profile shows three main peaks at 529.9, 531.2, and 532.5 eV associated with the oxygen species being in the form of an oxygen lattice (related to Cu species), Si–O–Al, and Si–O–Si linkages, respectively. − Furthermore, the presence of Cu species attributed to Cu + (Cu 2 O) and Cu 2+ (CuO) in the synthesized sample is confirmed by the Cu 2p XPS profile as exhibited in Figure d. The deconvolution of the Cu 2p spectrum shows six different peaks at various binding energies.…”

“…Z does not significantly induce embryonic mortality as shown in Figure 5a. However, relative to the control, 07Cu-Z at all concentrations (20,40,60,80, and 100 μg/mL) significantly decreases survival rates to 76.7 ± 2.9, 48.3 ± 2.9, 18.3 ± 2.9, 10.0 ± 5.0, and 0.0 ± 0.0%, respectively, as illustrated in Figure 5b. The estimated 50% lethal concentration (LC 50 ) of 07Cu-Z to zebrafish embryos at 96 hpf is 48.1 ± 2.7 μg/mL.…”

The high antibacterial and antiviral performance of synthesized copper(I) oxide (Cu 2 O) incorporated in zeolite nanoparticles (Cu-Z) was determined. Various Cu contents (1−9 wt %) in solutions were loaded in the zeolite matrix under neutral conditions at room temperature. All synthesized Cu-Z nanoparticles showed high selectivity of the cuprous oxide, as confirmed by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) analysis. An advantage of the prepared Cu-Z over the pristine Cu 2 O nanoparticles was its high thermal stability. The 7 and 9 wt % Cu contents (07Cu-Z and 09Cu-Z) exhibited the best activities to deactivate Gram-negative Escherichia coli and Grampositive Staphylococcus aureus bacteria. The film coated with 07Cu-Z nanoparticles also had high antiviral activities against porcine coronavirus (porcine epidemic diarrhea virus, PEDV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Specifically, the 07Cu-Z-coated film could reduce 99.93% of PEDV and 99.94% of SARS-CoV-2 viruses in 5 min of contact time, which were higher efficacies and faster than those of any previously reported works. The anti-SARS-CoV-2 virus film was coated on a low-cost PET or PVC film. A very small amount of cuprous oxide in zeolite was used to fabricate the antivirus film; therefore, the film was more transparent (79.4% transparency) than the cuprous oxide film or other commercial products. The toxicity of 07Cu-Z nanoparticles was determined by a toxicity test on zebrafish embryo and a skin irritation test to reconstruct a human epidermis (RhE) model. It was found that the impact on the aquatic environment and human skin was lower than that of the pristine Cu 2 O.

“…Figure 8 depicts XPS analyses performed to determine the elemental composition and electronic states of the as-prepared Dye sens ZEO. Figure 8a shows the presence of Al 2 O 3 species, as predicted by the presence of the Al 2p peaks at 74.2 eV and 77.4 eV [22]. Figure 8b displays the primary peak at 1071.3 eV [23] for the Na 1s peak at extreme resolution.…”

Heterostructured Dye Sensitized Zeolite nanocomposites (Dye sens ZEO) were successfully prepared by an ultrasonication method. The structural analyses of the heterogeneous catalyst were confirmed using various characterization techniques such as XRD, FT-IR, SEM, UV-DRS, PL, EDX, and Mapping. From the studies of FT-IR, EDX and SEM, the good binding between dye molecule and zeolite was confirmed. The SEM studies revealed that the prepared material in cubic morphology. The Dye sens ZEO nanocomposite participated to photodegradation process of levofloxacin (LVF) drug which was examined by UV visible spectroscopy. It shows that greatest photocatalytic activity within 60 mins under visible light irradiation. The identification of degradation intermediates of LVF using GC-MS spectroscopy. The dye molecules contain azo group and zeolite consist absorption properties were very useful for the transformation of electron which were enhanced the photocatalytic activity. In scavenger studies, hydroxide radical play a superior role in the photodegradation mechanism. Finally, the photocatalyst pick up from the degraded solution using centrifugation method and used to further cycle.
