“…Bimetallic palladium-zinc nanoparticles were synthesized from Citrus Paradisi (grapefruit peels) and their energy activity and photocatalytic activity took place in previous studies [51]. Trimetallic palladium-platinum-cobalt nanoparticles synthesized from Malus domestica peels (red apple peels) also took their place in photocatalytic activity [52]. As can be understood from here, nanoparticle production from natural resources as green synthesis has a highly interesting feature.…”

In this study, zinc nanoparticles (Zn NPs) were synthesized from the leaves of the plant Hypericum calycinum L by the biogenic method. Ultra-violet visible spectrum (UV-Vis), Fourier transmission electron spectroscopy (FTIR), transmission electron microscopy (TEM), and X-Ray were used to examine the absorbance, vibration bands, morphological structure, particle size, and crystalline size of the synthesized Zn NPs, respectively. Diffraction characterization (XRD) was performed. According to the results obtained, it was calculated that NPs gave peaks in the absorbance ranges of 274 and 370 nm, had a size of 29.066 ± 10.561 nm, and their crystalline size was 16 nm. Then, photocatalytic processes were started for the removal of methylene blue (MB) dye by combining the catalysis of NPs under the photocatalysis of sunlight. The degradation process provided by photocatalytic processes was carried out every half hour for 150 minutes. As a result of 150 minutes, the photodegradation efficiency was calculated to be 70%. This study supports future photodegradation studies for the removal of waste dyestuffs.

“…As a result, enormous advances have been seen in the recent years in the fabrication of peculiar synthetic nanomaterials composed of a mixture of different metal ions with distinct active sites, exhibiting an efficient coupling effect between the mixed metals and an improved material function with the ability to promote an efficient catalytic reaction or possess an incredible binding affinity for target macromolecules. For example, the synthesized or biofabricated nanocomposites such as Ag-Cu-Co as an antifungicide against Candida auris, Cu-Co-Ni for the photodegradation of dye, catalytic Cu-Au-Pt as a universal platform for biosensing and theranostics, Cu-Au-Pt as an electrocatalyst toward oxygen reduction reaction, Au-Cu-Zn for the degradation of organic dye, and Pd-Pt-Co for hydrogen production and photocatalysis are among a class of multivariate trimetallic nanocomposites that have been synthesized and characterized. While trimetallic nanocomposites have been shown to exhibit excellent catalytic and functional performance, including their unique functionality as nanozymes in both biological and electrochemical applications, − their use as a support for enzyme immobilization is scarcely reported.…”

In this work, a trimetallic (Ni/Co/Zn) organic framework (tMOF), synthesized by a solvothermal method, was calcinated at 400 and 600 °C and the final products were used as a support for lipase immobilization. The material annealed at 400 °C (Ni-Co-Zn@400) had an improved surface area (66.01 m2/g) and pore volume (0.194 cm3/g), which showed the highest enzyme loading capacity (301 mg/g) with a specific activity of 0.196 U/mg, and could protect the enzyme against thermal denaturation at 65 °C. The optimal pH and temperature for the lipase were 8.0 and 45 °C but could tolerate pH levels 7.0–8.0 and temperatures 40–60 °C. Moreover, the immobilized enzyme (Ni-Co-Zn@Lipase, Ni-Co-Zn@400@Lipase, or Ni-Co-Zn@600@Lipase) could be recovered and reused for over seven cycles maintaining 80, 90, and 11% of its original activity and maintained a residual activity >90% after 40 storage days. The remarkable thermostability and storage stability of the immobilized lipase suggest that the rigid structure of the support acted as a protective shield against denaturation, while the improved pH tolerance toward the alkaline range indicates a shift in the ionization state attributed to unequal partitioning of hydroxyl and hydrogen ions within the microenvironment of the active site, suggesting that acidic residues may have been involved in forming an enzyme–support bond. The high enzyme loading capacity, specific activity, encouraging stability, and high recoverability of the tMOF@Lipase indicate that a multimetallic MOF could be a better platform for efficient enzyme immobilization.

Today, the development of green nanocatalysts is among the popular topics due to the need for energy production and the cleaning of organic pollutants. In this approach, Bacillus thuringiensis, a bacterium, was used as a biosupport of ruthenium/nickel co-doped zinc nanoparticles (btRNZn NPs) to release hydrogen from the methanolysis of sodium borohydride (NaBH 4 ). In addition, their photocatalytic activity was reported against Methyl Orange (MO) organic dye. This study focused on the preparation, characterization, and catalytic and photocatalytic activity of the btRNZn biocatalyst for the release of hydrogen from the methanolysis of NaBH 4 and removal of MO dye. According to TEM analysis, the average size of btRNZn NPs was found to be 11.78 nm; in addition, btRNZn NPs showed a photodegradation effect of 68.2% against MO dye at 90 min, and its photocatalytic mechanism was discussed. The effects of the catalyst, substrate, and temperature in the methanolysis reaction of NaBH 4 in the presence of the catalyst were investigated extensively. The reaction kinetics was calculated, and TOF, activation energy, and enthalpy energy were measured as 2497.14 h −1 , 14.89 kJ/mol, and 12.35 kJ/mol, respectively. It was observed that the methanolysis process is a first-order reaction based on the amount of the catalyst and substrate. This study aimed to synthesize a nanobiocatalyst (btRNZn NPs) by a biological method, and it will be used as a great photocatalyst to prevent wastewater pollution; also, it can be an excellent catalyst to produce hydrogen from NaBH 4 methanolysis. The application of btRNZn NPs in solar photocatalysis to prevent wastewater pollution and to research it for energy production through hydrogen creation are both made clear by these studies.
