“…The transmittance enhancement of the broad peak at 1411 cm -1 may be caused by the C=C stretching vibration in the benzene ring of MG. The Mg-O-Mg vibration modes of MgO [37] appeared between 750 cm -1 and 583 cm -1 . The peak at 1624 cm -1 and 3420 cm -1 was due to H-O-H bending vibration and stretching vibration of -OH of adsorbed water, respectively [9, 38].…”

The environmental pollution caused by organic dyes has damaged serious harm to human life. Hence, a series of Zr-Mg composite oxide nanoclusters with different metal ratios were synthesized by solvothermal method for adsorption of malachite green in aqueous solution. The optimal adsorbent with Zr/Mg metal molar ratio of 1 : 2 presented good adsorption performance, which adsorption capacity reached 12647.60 mg/g, and removal rate of malachite green reached more than 99%. These adsorbents were characterized by X-ray diffraction, Fourier-transform infrared spectra, nitrogen adsorption-desorption, scanning electron microscope, transmission electron microscope, and other methods. Influence of initial concentration of malachite green solution, pH, adsorption temperature, and contact time on absorption efficiency was investigated through batch experiments. Pseudo-second-order kinetic model can well describe the adsorption kinetic data. The three-parameter Sips isotherm model was more suitable for predicting the experimental results than Langmuir and Freundlich, and the adsorption process was endothermic.

“…Many studies have shown that double cation doped ZrO 2 could reduce the test temperature and improve its conductivity when compared to the single cation stabilized zirconia [25,26,27,28,29,30]. For instance, Liu et al found that 1 wt % Al 2 O 3 doped 8 mol % Y 2 O 3 stabilized ZrO 2 (8YSZ) reduced the sintering temperature of YSZ and improved the output of the fuel cell [26].…”

Yb3+ and Y3+ double doped ZrO2 (8YSZ+4Yb2O3) samples were synthesized by a solid state reaction method. Moreover, 8YSZ+4Yb2O3-NaCl/KCl composites were also successfully produced at different temperatures. The 8YSZ+4Yb2O3, 8YSZ+4Yb2O3-NaCl/KCl (800 °C), and 8YSZ+4Yb2O3-NaCl/KCl (1000 °C) samples were characterized by x–ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that a dense composite electrolyte was formed at a low temperature of 800 °C. The maximum conductivities of 4.7 × 10−2 S·cm−1, 6.1 × 10−1 S·cm−1, and 3.8 × 10−1 S·cm−1 were achieved for the 8YSZ+4Yb2O3, 8YSZ+4Yb2O3-NaCl/KCl (800 °C), and 8YSZ+4Yb2O3-NaCl/KCl (1000 °C) samples at 700 °C, respectively. The logσ~log (pO2) plot result showed that the 8YSZ+4Yb2O3-NaCl/KCl (800 °C) composite electrolyte is a virtually pure ionic conductor. An excellent performance of the 8YSZ+4Yb2O3-NaCl/KCl (800 °C) composite was obtained with a maximum power density of 364 mW·cm−2 at 700 °C.
