“…Substitution of Co ion in Ba 2 Ni x Co 2−x O 6 enhanced the oxygen desorption amount compared to Ni ion. Compared to single BaCoO 3 perovskite, which have been investigated in our pervious study, the double Ba 2 Ni x Co 2−x O 6 in this study exhibited the novel oxygen desorption performance 25 . To our understanding, Co‐based perovskite‐type oxygen‐permeable membrane materials have relatively high oxygen permeability.…”

Summary Novel oxygen‐deficient double‐perovskite type oxide Ba2NixCo2−xO6 was applied to produce O2/CO2 mixed stream gas for oxyfuel combustion application. A series of different Co concentration substituted Ba2NixCo2−xO6 was synthesized by an EDTA‐citrate sol‐gel combustion method. The oxygen carriers, Ba2Ni0.25Co1.75O6, Ba2Ni0.45Co1.55O6, Ba2Ni0.65Co1.35O6 and Ba2Ni0.85Co1.15O6 were c\characterized by scanning electron microscopy and cyclic oxygen adsorption/desorption experiments. The results showed that the capacity of provided O2 was improved by the partial substitution of Ni by Co. In addition, the synthesized perovskites exhibit good regeneration ability. The optimal degree of Co substitution was x = 0.25 for Ba2NixCo2−xO6 with consideration of oxygen desorption ability. Therefore, Ba2Ni0.25Co1.75O6 was selected to examine the influence of the operating parameters on the oxygen release performance. It was found that the desorption temperature and CO2 partial pressure are the two main operating parameters for the oxygen desorption performance. Further, the proposed novel double perovskite Ba2Ni0.25Co1.75O6 provided excellent performance, the O2 production of Ba2Ni0.25Co1.75O6 can still reach 120 mg/g after 10 cycles.

“…The physical and chemical properties and the catalytic activities of these perovskites are greatly affected by the nature, oxidation states and the stochiometry of the elements of A and B . Their compositions, with different combinations of charged cations in the A and B sites (A cation can be mono, di or trivalent, whereas B can be a di, tri, tetra, penta or hexavalent cation) , can be varied over a wide range by partial or total substitutions with a great range of metal cations, the resulting formula is in

{{A A}^{^{'}} B B}^{^{'}} O_{3}

form (

In this study, the perovskite‐type oxides Ba0.5Sr0.5Ni0.2Co0.6Fe0.2O3‐δ (BSNCF) with different B‐site transition metal elements were investigated as a new catalyst for methanol oxidation. They were prepared by the partial substitution of cobalt by nickel in Ba0.5Sr0.5Co0.8Fe0.2O3‐δ (BSCF) sample. Both materials prepared using a combined citrate/EDTA complexing method and their catalytic activitiesfor methanol oxidation were comparativelystudied using cyclic‐voltammetry (CV) and chronoamperometry (CA) in alkaline media at room temperature. Structural, textural, morphological and redox properties of the synthesized solids were investigated by several physicochemical methods such as XRD, FTIR, LRS, SEM‐EDX, BET and H2‐TPR. The as‐prepared materials were obtained with high purity and high crystallinity. The partial substitution of cobalt by nickel in BSCF perovskite changes the structure of the solid which pass from cubic structure to a mixture of cubic and hexagonal forms. This change is accompanied by an increase in BET surface area and a decrease in crystalline size. For the electro‐catalysis measurements, results demonstrated that partially substituting of Co by Ni in BSCF structure enhance the electro‐catalytical activity towards the oxidation of methanol under alkaline conditions, making it an electro‐catalyst candidate for practical utilization in DMFCs.
