Degradation Properties

Nanoparticles have a greater surface area and thus precise characteristics in the implementation and development of nano-specifically dimensioned materials. The Photocatalytic degradation properties of cadmium oxide (CdO) and manganese oxide (MnO) nanoparticles (NPs) vary significantly than those of standard products due to their large bandwidth and energy binding. These nanoparticles have potential applications in antibacterial, antioxidant, antimicrobial etc. these nanoparticles were produced using a number of ways such as sol-gel, co-precipitation, green synthesis, microwave etc.

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan zat aditif terhadap ukuran dan bentuk nanopartikel yang dihasilkan serta kemampuannya sebagai katalis dalam proses degradasi zat warna rhodamin B. Nanopartikel yang diperoleh, dikarakterisasi menggunakan XRD (X-Ray Diffraction) dan SEM (Scanning Elektron Microscope) serta penentuan aktivitas katalitik dalam proses degradasi terhadap zat warna rhodamin B dengan spektrofotometer UV-Vis. Hasil penelitian menunjukkan sintesis nanopartikel menggunakan aditif etilendiamin lebih baik dibandingkan dengan aditif etilen glikol karena ukuran nanopartikel berkisar antara 5,66-33,38 dalam bentuk tetragonal. Morfologi nanopartikel mangan oksida terlihat berbentuk bulat yang seragam. Nanopartikel mangan oksida hasil sintesis mampu mempercepat proses degradasi warna rhodamin B dengan persentase degradasi mencapai 85,6%.

This study aims to determine the effect of adding substances additives on the size and shape of the nanoparticles were produced and their ability as catalysts in the degradation process of Rhodamin B. Nanoparticles were obtained, characterized using XRD (X-Ray Diffraction)and SEM (Scanning Elektron Microscope)and determination of catalytic activity in the degradation process of rhodamine B dyes with UV-Vis spectrophotometer. The results showed that the synthesis of nanoparticles using ethylenediamine additives was better than ethylene glycol additives because the size of the nanoparticles ranged from 5.66 to 33.38 in the tetragonal form. The morphology of manganese oxide nanoparticles looks uniform in shape. Manganese oxide nanoparticles can accelerate the degradation process of Rhodamin B with a percentage of degradation reaching 85.6%. Keywords: Nanoparticles, Manganese Oxide, Sol gel and Rhodamin B

ABSTRACTObjective: Metal oxide nanoparticles are widely attracted researchers due to their potential applications in a variety of fields, especially medicinalimportance. It has been shown that biofunctionalization of metal nanoparticles with the specified bioactive materials produces the significantlyimproved bioactive materials with the essential biological properties and advanced features. According to the reports, manganese oxide nanoparticles(MONPs) possess highly magnetic properties leads to develop for use in research and biomedical applications. In this evaluation, we focused on thesynthesis of MONPs through a green methodology and their antimicrobial activity changes when functionalized with curcuminaniline derived fromturmeric plants.Methods: First, curcumin has been isolated from turmeric plant (BSR-01) to synthesize curcuminaniline biomaterial. On the other hand, manganesenanoparticles are synthesized by the green synthesis method using lemon extract and curcumin. Finally, the synthesized curcuminaniline isfunctionalized with MONPs. The synthesized nanoparticles are characterized by ultraviolet-visible, Fourier transform infrared, scanning electronmicroscope and transmission electron microscopy techniques. The antimicrobial activity of the obtained nonfunctionalized and biofunctionalizednanoforms are tested against some Gram-negative and Gram-positive bacterial strains as well as fungal strains.Results: The morphological studies represented that MONPs are of eclipsed and spherical morphology with size about 50±5 nm and biofunctionalizednanoparticles are of spherical morphology with size about 50±10 nm. The antibacterial and antifungal tests revealed that biofunctionalized MONPsare exhibited significantly higher antimicrobial activity.Conclusion: This investigation clearly demonstrated that MONPs are shown significantly higher biocidal activity when biofunctionalized withmodified curcumin material. This may help in the future medicinal and pharmaceutical industries to develop new inventions.Keywords: Green synthesis, Nanoparticles, Curcumin, Curcuminaniline, Soxhlet extraction, Antimicrobial activity.

New Strategy

In the present work a remarkably simple procedure for the elaboration of wet cellulose film containing manganese oxide nanoparticles was developed. The films were produced using a mold made by 3D printing using cellulose dissolved in an ionic liquid, which allows the production of thin and homogeneous films of different shapes, types and designs which cannot be made using conventional techniques. Thanks to this possibility, the final catalytic object can be implemented in specific reactors. Manganese oxide nanoparticles were prepared as a colloidal solution by a redox/sol-gel procedure and then deposited on the cellulose films by wet impregnation. The catalytic film obtained was tested in the decomposition of a dye, indigo carmine (IC), in the absence of light. The influence of the pH of the solution on the decomposition rate was investigated. IC total decomposition was measured after 1-h reaction at pH below 3. At pH = 2, no deactivation of the catalyst was observed even after four decomposition cycles. This work provides a new strategy to design cellulose-based catalysts for dye removal from wastewater.
