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

Abstract 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 (τ = 0.943) and degree of reaction (α = 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 Si 2 Al 2 O 5 (OH) 4 ·CsCl·H 2 O 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 ( σ ac  ~ 10 − 2  S·m − 1 ) and can be classified as a superionic conductor.
