Abstract

Room-temperature synthesis of transition metal ( TM = Co, Ni and Mn ) oxide intercalated clays has been developed, which extends the potentiality of clay based materials for the design of electroactive nanophase. The structure was examined by using powder XRD - one-dimensional Fourier analysis, magnetic susceptibility measurement as well as conventional analytical methods. From the results, it was revealed that the oxidation by using NaClO as the oxidative reagent affords a new expanded layer structure with a basal spacing of about 1.96 nm wherein a conductive TM oxide sheetadjacent to two hydrated sodium ion layers resides in the gallery of the clay. The resultant sodium cobaltate interlayered smectite bears multi-functionality; an apparent bulk conductivity in the order of 10−5 Scm−1 and a cation exchange ability.

[5] The analysis was carried out by using the following equations, I001 = A*Lp(θ)*|F001|2 , where Lp(θ) = (1+cos2(2θ))/(sin2(θ)cos(θ)), and A stands for a instrumental constant. The electorn density ρ(z) was calculated by using a equation, ρ(z) = ∑F001cos(2πzl). The signs of Fobs were phased with the calculated ones on the basis of the structure model.Google Scholar
