Hybrid polypyrrole (PPy) nanoparticles were prepared using a low-temperature oxidative polymerization process in an acidic solution with polyethyleneimine (PEI) as a template and amine source. The results showed that the nanoparticles have an amorphous structure in the X-ray diffractogram and exhibited good dispersibility in water, uniform size, and a specific conductivity ranging from 0.1 to 6.

This study aimed to assess the UV-shielding features of the PMMA-based thin film coatings with the addition of TiO and ZnO nanoparticles as nanofillers considering different contents. Furthermore, the effect of TiO/ZnO nanohybrids at different ratios and concentrations was examined. The XRD, FTIR, SEM, and EDX analyses characterized the prepared films' functional groups, structure, and morphology.

In this study, we fabricated an economical, non-toxic, and convenient magnetic nanocomposite of CuFeO nanoparticles (NPs)/carbon quantum dots (CQDs) of citric acid via the co-precipitation method. Afterward, obtained magnetic nanocomposite was used as a nanocatalyst to reduce the ortho-nitroaniline (o-NA) and para-nitroaniline (p-NA) using a reducer agent of sodium borohydride (NaBH). To investigate the functional groups, crystallite, structure, morphology, and nanoparticle size of the prepared nanocomposite, FT-IR, XRD, TEM, BET, and SEM were employed.

The primary objective of this research is to investigate the reduction of 4-nitroaniline (4-NA) and 2-nitroaniline (2-NA) using synthesized copper ferrite nanoparticles (NPs) via facile one-step hydrothermal method as a heterogeneous nano-catalyst. Nitroanilines were reduced in the presence and without the catalyst with a constant amount (100 mg) of reducing agent of sodium borohydride (NaBH ) at room temperature in water to amino compounds. To characterize the functional groups, size, structure, and morphology of as-prepared magnetic NPs, FTIR, XRD, SEM, and TEM were employed.
