“…In accordance with some reports [2,42,43], the vibrations of the stannate group ( − SnO 3 2 ) produce high intensity infrared absorption bands in the ranges of 300-400 and 600-700 cm À 1 [42], with the stretching vibration of the Sn-O bond being located at about 674 cm À 1 [44]. Looking at Table 3.…”

a b s t r a c tDensity functional theory (DFT) and density functional perturbation theory (DFPT) calculations were used to investigate the vibrational and thermodynamic properties of orthorhombic stannate CaSnO 3 compound. Our approach was based on the generalized gradient approximation with dispersion correction (GGA þ D), considering the norm-conserved pseudopotentials. The phonon dispersion relation as well as theoretical peaks of the infrared (IR) and Raman spectrum in the frequency range of 100-800 cm À 1 was analyzed and assigned. The thermodynamic potentials and the specific heat at constant volume of the CaSnO 3 compound are also calculated, whose dependence with the temperature are discussed.

“…5). The appearance of SnO 2 and carbonates impurities in the materials was already observed in many doped and undoped alcalino earth stannates [41,42,22]. Strontium carbonate is difficult to remove completely in wet chemical method, and the remaining quantity should decomposing above 1073 K as mentioned in literature [43].…”

Acetamiprid, a type of new neonicotinoid pesticide, shows a high threat to water systems. Electro-catalytic degradation of acetamiprid was evaluated using an Er doped Ti/SnO 2 -Sb electrode prepared by the Pechini method. The acetamiprid degradation obeys first order reaction kinetics and is controlled by mass transport and oxygen evolution. TOC removal efficiency and UV scan curves revealed that some intermediate products were produced by the Er doped Ti/SnO 2 -Sb electrode. Through electrospray ionization quadrupole time-of-flight tandem mass spectrometry, the ion mass-to-charge ratio of intermediate products was determined. Combining the experimental results, a degradation pathway was proposed for the electro-catalytic degradation of acetamiprid. Electrodes were mainly characterized by linear sweep voltammetry and cyclic voltammetry. The acetamiprid and TOC concentrations were reduced to 87.45% and 69.31%, respectively, after 180 min of electrolysis at 10 mA cm À2 .
