In this study, a novel nanobiocomposite consisting of agar (Ag), tragacanth gum (TG), silk fibroin (SF), and MOF-5 was synthesized and extensively investigated by various analytical techniques and basic biological assays for potential biomedical applications. The performed Trypan blue dye exclusion assay indicated that the proliferation percentage of HEK293T cells was 71.19%, while the proliferation of cancer cells (K-562 and MCF-7) was significantly lower, at 10.74% and 3.33%. Furthermore, the Ag-TG hydrogel/SF/MOF-5 nanobiocomposite exhibited significant antimicrobial activity against both E. coli and S. aureus strains, with growth inhibition rates of 76.08% and 69.19% respectively. Additionally, the hemolytic index of fabricated nanobiocomposite was found approximately 19%. These findings suggest that the nanobiocomposite exhibits significant potential for application in cancer therapy and wound healing.

“…The CO link in carbonyl compounds has been reported to be activated by surface Cu + species. ,, Hence, probably in our case, Cu + has been shown to prevent the production of THFA by inhibiting the hydrogenation of the furan ring in the FFA molecule. As high temperatures reduces the activity of nickel to hydrogenate, CPO rather than CPL is the primary hydrogenation product . Recently, Hronec et al also demonstrated that the link of Cu + species and the CO link in FFA contributed significantly to the development of excellent catalytic activity in the selective transformation of FFA into CPO .…”

In the pursuit of the net-zero goal, the use of biomass-derived feedstock for the manufacture of fuels, chemicals, and polymers has taken a central stage. In this regard, selective hydrogenation of furfural, a platform chemical obtained from lignocellulosic biomass, to cyclopentanone (CPO) is commercially attractive. In the current work, a bimetallic catalyst based on transition metals Ni and Cu loaded onto the MOF-5 support, synthesized by the incipient wetness process, was used in the hydrogenation of furfural to selectively produce CPO. 5 wt % Ni–Cu (1:1) @MOF-5 catalyst gave 100% furfural conversion with 96% CPO yield at 150 °C and 25 bar hydrogen pressure in 5 h. The doping of nickel and copper on MOF-5 leads to a synergetic effect, providing enhanced hydrostability, reducing ability, and promotion of the CO bond, inhibition of furan ring hydrogenation, and suppression of the formation of a likely byproduct tetrahydrofurfuryl alcohol. In addition to enhancing reactant adsorption, the inclusion of Ni-Cu on the MOF also provides weak Lewis acid sites, enhancing the selectivity of CPO. The optimization of the process parameters was done. Reaction mechanisms and kinetics were studied. The virgin and reused catalysts were thoroughly characterized to shed light on the reaction mechanism and selectivity. This is a biobased clean and green process for the synthesis of a valuable chemical.
