“…The synthesis of Nd 2 Zr 2 O 7 by several precursor routes such as the sol-gel and citrate methods has also been reported [12][13][14][15] [12,13]. Zhang assigns Nd 2 Zr 2 O 7 synthesised at 600 °C (for ten minutes) to the pyrochlore structure despite the PXRD data showing a poorly crystalline sample [15].…”

AbstractThe structural characterisation of Nd 2 Zr 2 O 7 prepared via a precursor route was performed using a combination of local and average structure probes (neutron total scattering, X-ray and neutron diffraction). We present the first total scattering and reverse Monte Carlo (RMC) modelling study of Nd 2 Zr 2 O 7 , which provides compelling evidence for the adoption of a disordered fluorite-type structure by Nd 2 Zr 2 O 7 prepared by a low-temperature precursor route.Annealing the material at high temperatures leads to a transformation to a pyrochlore-type structure; however, Rietveld refinement using powder neutron diffraction data shows that the oxygen sublattice retains a degree of disorder.

“…One of the considerable and attractive nanoscale materials is Ln 2 Zr 2 O 7 -kind ternary oxides (Ln is a lanthanide ion) that they find applications in high-temperature fuel cell, photocatalyst, oxide conductor, fluorescence centers, oxygen monitoring sensors, gas turbines, actinide transmutation, oxidation catalysts and nuclear waste form owing to their excellent and remarkable characteristics [5][6][7][8][9][10]. To date, different ways, such as hydrothermal, sol-gel combined electrospinning, complex precipitation, Pechini polymeric route, solid-state reaction and sol-gel have been presented for the production of Ln 2 Zr 2 O 7 [11][12][13][14][15][16][17][18]. The synthesis of Ln 2 Zr 2 O 7 and its nanocomposites through Pechini polymeric approach as friendly to the environment way provides a reliable, simple and cost effective process to control their grain size, shape and purity.…”

Nd 2 Zr 2 O 7 -ZrO 2 nanocomposites were prepared via a facile process with propylene glycol as novel connecting agent and benzene tricarboxylic acid as a new complexing agent. The as-obtained Nd 2 Zr 2 O 7 -ZrO 2 nanocomposites were characterized by transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy, energy dispersive X-ray microanalysis (EDX), Fourier transform infrared (FT-IR) spectroscopy, 2 field emission scanning electron microscopy (FESEM), and X-ray diffraction (XRD). According to the morphological studies of the as-synthesized nanocomposites, it was found that the shape and particle size of Nd 2 Zr 2 O 7 -ZrO 2 nanocomposites depended on the space-filling template type, dosage of space-filling template and tricarboxylic acid as complexing agent. Nd 2 Zr 2 O 7 -ZrO 2 nanocomposites with different shapes and grain sizes have been synthesized. The photocatalytic behavior of as-produced Nd 2 Zr 2 O 7 -ZrO 2 nanocomposites was also investigated through photodegradation of methylene blue dye and 2-naphthol as water pollutants.
