3 mphyd

In this research work, the required chemicals were used as received without further purification. The inorganic salts of transition metals such as copper(II) chloride (CuCl₂), manganese(II) chloride (MnCl₂), gadolinium(III) chloride, and ammonium hydroxide (NH₄OH) were purchased from well-known Sigma-Aldrich, which was deployed to prepare ternary CuO/MnO₂/Gd₂O₃ NSs. As a part of these studies, the analytical grade chemicals 2,4-DNP (2,4-dinitrophenol), 3,4-DAT (3,4-diaminotoluene), pyridine, BH (benzaldehyde), 3-chlorophenol, THF (tetrahydrofuran), methanol, 3-MPHyd (3-methoxyphenylhydrazine), AH (ammonium-hydroxide), coating agent nafion (in 5% ethanol), NaH₂PO₄, and Na₂HPO₄ were also bought from the Sigma-Aldrich and deployed as-received. For the details characterization of synthesized CuO/MnO₂/Gd₂O₃ NSs, conventional XRD, XPS, FTIR, UV/Vis and FESEM were implemented to evaluate the structural, crystalline, functional, optical, morphological and elemental analyses. The reliable current versus potential (electrochemical method) was used to determine 3-MPHyd with active CuO/MnO₂/Gd₂O₃ NSs material by using Keithley electrometer (6517A, USA) at room conditions.
