Synthesis, Structure, and Electrical Conductivity of A′[A2B3O10](A′=Rb, Cs; A=Sr, Ba; B=Nb, Ta): New Members of Dion–Jacobson-Type Layered Perovskites

Mixed potential protonic?electronic conductivity in the Dion?Jacobson-type layered perovskites in hydrogen-containing atmosphere and their application in ammonia sensors

“…The activation energy obtained in air (Table 1) is due to migration of the alkali ions between the perovskite layers and is comparable to that of other ionic conductors based on perovskite-related structure [4b, 11,[14][15][16].…”

“…Accordingly, the observed EMF in the H 2 ||air cell is mainly due to ion (most likely proton) migration from anode to cathode according to Eqs. (12), (13), and (14). We also found that that hydrogen gas concentration cell ( P H 2 W ||P H 2 V ) using as-prepared KCa 2 Nb 3 O 10 as electrolyte shows theoretical EMF at room temperature for the as-prepared sample, according to the equation:…”

“…The D-J phases have low interlayer cation density compared to the R-P phases. Accordingly, among the two types of structures, the D-J phases exhibit several superior properties such as fast ion exchange and high electrical conductivity [11][12][13][14][15][16] compared to R-P phases. Fig.…”

Synthesis and electrochemical properties study of novel intercalation compound of KCa 2 Nb 3 O 10 with cationic methylene blue

“…The layered material, KCa 2 Nb 3 O 10 , was prepared by the solid-state reaction of stoichiometric quantities of a high-purity mixture of K 2 CO 3 , CaCO 3 and Nb 2 O 5 at 1250°C for 24 h [10]. The intercalation compound of KCa 2 Nb 3 O 10 with MB + is difficult to prepare by a direct reaction because of the bulkiness of MB, thus a two-step intercalation with PrNH 3 + -Ca 2 Nb 3 O 10 as a precursor was taken to prepare the nanocomposite MB + -Ca 2 Nb 3 O 10 .…”

Electronic, optical and photocatalytic properties of three-layer perovskite Dion–Jacobson phase CsBa2M3O10(M = Ta, Nb): a DFT study

“…In the DJ and RP phases, the thickness of perovskite slabs relies on the number of BO 6 octahedral (n) corner shared along the c-axis [1][2][3][4] . In the DJ and RP phases, the thickness of perovskite slabs relies on the number of BO 6 octahedral (n) corner shared along the c-axis [1][2][3][4] .…”
