“…The Dy 2 Cu 2 O 5 of SSM showed type III isotherm profiles according to IUPAC classification, indicating weak adsorbent-adsorbate interaction without the appearance of “ink-bottle”pores between particles 33,34 . By comparison, the Dy 2 Cu 2 O 5 of CCM depicted type III isotherm curves with approximate H2 hysteresis loop.…”

Dy2Cu2O5 nanoparticles with perovskite structures were synthesized via a simple solution method (SSM) and a coordination compound method (CCM) using [DyCu(3,4-pdc)2(OAc)(H2O)2]•10.5H2O (pdc = 3,4-pyridinedicarboxylic acid) as precursor. The as-prepared samples were structurally characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), x-ray photoelectron spectroscopy (XPS) and standard Brunauer–Emmett–Teller (BET) methods. Compared to the aggregated hexahedral particles prepared by SSM, the Dy2Cu2O5 of CCM showed hollow spherical morphology composed of nanoparticles with average diameters of 100–150 nm and a larger special surface area up to 36.5 m2/g. The maximum adsorption capacity (Q m) of CCM for malachite green (MG) determined by the adsorption isotherms with different adsorbent dosages of 0.03–0.07 g, reached 5.54 g/g at room temperature. The thermodynamic parameters of adsorption process were estimated by the fittings of the isotherms at 298, 318, and 338 K, and the kinetic parameters were obtained from the time-dependent adsorption isotherms. The results revealed that the adsorption process followed a pseudo-second-order reaction. Finally, the adsorption mechanism was studied using a competitive ion (CI) experiments, and the highly efficient selective adsorption was achieved due to strong O-Cu and O-Dy coordination bonds between Dy2Cu2O5 and MG.
