Impact of low normality of cesium chloride (n=0.3 N) on the electrical features of nacrite-[(CsCl)(n)] nanohybrid subjected to excitation of frequency under controlled temperature

摘要

A series of nanohybrid materials with different (CsCl)(n) normalities (n = 0.05 N, 0.1 N, 0.3 N, 0.5 N, 1 N, 2 N and 3 N) was synthesized by indirect intercalation of nacrite. Systematic and kinetic X-ray diffraction surveys reveal that the optimal nanohybrid with the highest intercalation rate (tau = 0.943) and degree of reaction (alpha = 0.860) corresponds to (n = 0.3 N) normality value of aqueous CsCl solution and was labeled nacrite-[(CsCl)(n = 0.3 N)]. Its half-unit cell structural formula as deduced by agreement between experimental and simulated patterns (R-p = 7.30%) was Si2Al2O5(OH)(4)center dot CsCl center dot H2O with a d(002)-value equals to 1.05 nm. The atomic composition and the vibrational description of the nacrite-[(CsCl)(n = 0.3 N)] nanohybrid was made respectively by means of energy -dispersive X-ray spectroscopy coupled to transmission electron microscope and infrared spectroscopy techniques. The electrochemical impedance spectroscopy reveals that nacrite-[(CsCl)(n = 0.3 N)] nanohybrid material heated to higher temperatures exhibits an excellent ionic conductivity (sigma(ac) similar to 10(-2) Sm-1) and can be classified as a superionic conductor.
