This study focuses on the photocatalytic degradation of Rhodamine B (RhB) in heterogeneous and homogeneous photo-Fenton reactions. In system, iron(II) doped copper ferrite CuII(x)FeII(1-x)FeIII2O4 nanoparticles (NPs) prepared our previous work were employed as potential catalysts. The photodegradation RhB was carried out a quartz cuvette located diode array spectrometer. experimental conditions...
A Cu(II)-sensing, ratiometric, and selective fluorescent sensor 1, N-butyl-4,5-di[(pyridin-2-ylmethyl)amino]-1,8-naphthalimide, was designed and synthesized on the basis of the mechanism of internal charge transfer (ICT). In aqueous ethanol solutions of 1, the presence of Cu(II) induces the formation of a 1:1 metal-ligand complex, which exhibits a strong, increasing fluorescent emission centere...
We report a series of 3d-4f complexes {Ln2 Cu3 (H3 L)2 Xn } (X=OAc(-) , Ln=Gd, Tb or X=NO3 (-) , Ln=Gd, Tb, Dy, Ho, Er) using the 2,2'-(propane-1,3-diyldiimino)bis[2-(hydroxylmethyl)propane-1,3-diol] (H6 L) pro-ligand. All complexes, except that in which Ln=Gd, show slow magnetic relaxation in zero applied dc field. A remarkable improvement of the energy barrier to reorientation of the magnetis...
Jahn–Teller distortions are often observed in CuII-containing complex oxides resulting remarkable changes of physical properties. Tuning the with pressure has attracted considerable interest but is less studied high-entropy (HEOs). We found that can suppress structural originating from effect CuO6 octahedra rock salt-type (Mg0.2Ni0.2Co0.2Zn0.2Cu0.2)O HEO and significantly modify its electronic ...
