In this review, the recent progress in the application of an important category of materials, i.e. ABO 3 perovskite-type compounds in the fields of energy storage and conversion, is reviewed. Four main areas, as materials for oxygen transporting membrane toward the application in oxy-fuel combustion, as key material for solid oxide fuel cells for efficient power generation from fuels, as room-temperature electrocatalysts for oxygen reduction reaction and oxygen evolution reaction, and as material for solar cells for solar energy harvest, are referred. Our past efforts in these research areas are emphasized. Some prospects about the future development in the application of perovskite materials in energy storage and conversion is proposed.

Metal-air batteries (MABs), particularly rechargeable MABs, have gained renewed interests as a potential energy storage/conversion solution due to their high specific energy, low cost, and safety. The development of MABs has, however, been considerably hampered by its relatively low rate capability and its lack of efficient and stable air catalysts in which the former stems mainly from the sluggish kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) and the latter stems from the corrosion/oxidation of carbon materials in the presence of oxygen and high electrode potentials. In this review, various carbon-composited bifunctional electrocatalysts are reviewed to summarize progresses in the enhancement of ORR/OER and durability induced by the synergistic effects between carbon and other component(s). Catalyst mechanisms of the reaction processes and associated performance enhancements as well as technical challenges hindering commercialization are also analyzed. To facilitate further research and development, several research directions for overcoming these challenges are also proposed.

“…As mentioned in Section 1, Yuasa et al reported the synthesis of perovskite‐type solid solution particles by the same RM methods with the carbon support at 873 K calcination, however, the size of them was large, about 20 nm. [ 31–34 ] The surface of TiO 2 , especially in an aqueous solution, has high density of hydroxyl groups compared to the carbon support. Therefore, it is speculated that the surface hydroxyl groups formed stronger interaction with the CFCO precursor, and such an interaction acts as the “linker” between the precursors and the TiO 2 surface to stably hold the small particles and to suppress the diffusion and aggregation of them during calcination at the high temperature.…”

“…The RM method is one of the proven methods to synthesis of nanosized metal oxides. [ 31–34 ] Yuasa et al reported the syntheses of perovskite‐type LaMnO 3 [ 31,32 ] and La 1− x Ca x Mn 1− y Fe y O 3 [ 33,34 ] on a carbon support prepared by the RM method. The particle size of LaMnO 3 and La 1− x Ca x Mn 1− y Fe y O 3 synthesized by the RM method was smaller than those by the conventional methods, even though the particle sizes of the former ones were not several nanometer scales, i.e., ≈20 nm.…”

transfer processes. [2,3] For highly efficient water splitting method, we believe it is quite important to find an effective photocatalyst for OER. Many researchers have attempted to improve photocatalytic activity by loading cocatalysts, which are active for the OER step on photocatalysts or semiconductors. [1][2][3] Although noble metal oxides such as RuO 2 [4,5] and IrO 2 [6] show higher catalytic activity for OER and have also been used as cocatalysts of photocatalysts, the lack of sufficient reserves prohibits their large-scale uses. Therefore, it is necessary to find a promising OER cocatalyst consisting of only transition metal elements. Among transition metal cocatalysts, cobalt-containing materials, such as cobalt oxides (CoO x ) [8][9][10] and cobalt phosphate (Co-Pi), [11,12] are ones of the most frequently studied as the OER cocatalysts, whereas their OER activity are not higher than those of the noble metal oxides. Recently we found that brownmillerite (BM)-type Ca 2 FeCoO 5 (CFCO) possessed higher catalytic OER activity than the noble metal oxides in an alkaline solution. [13,14] The BM structure is categorized as an oxygen-deficiencyordered perovskite-type structure containing a layered arrangement of octahedral (Oh) BO 6 and tetrahedral (Td) BO 4 . [15][16][17][18] Such Oh-and Td-sites are likely to play distinct roles in the enhanced OER activity: the former mainly decreases the overpotential, and the latter enhances the OER current. [13] Therefore, BM-type CFCO is expected to act as a new active cocatalyst for OER by combination with photocatalysts.In general, the particle size of cocatalyst is several nanometers due to increasing interface between the parent catalyst and the cocatalyst, and exposure of the active sites. [4][5][6][7][8][9][10][11][12] For example, Liu et al. reported size influence of metal oxide cocatalysts on photocatalytic activity of TiO 2 nanosheets for OER. [19] Charge-transfer process in TiO 2 was significantly accelerated by loading the metal oxides clusters with ≈2 nm diameter, leading to enhance the photocatalytic water oxidation rate to oxygen. In solutions, on the other hand, nanometric oxide particles have been utilized as the OER cocatalysts. [20][21][22][23] For example, Maeda and co-workers reported OER catalytic activity of Fe(III)-Cr(III) oxide solid solution [20] combined with PdCrO x[21] on SrTiO 3Brownmillerite-type Ca 2 FeCoO 5 (CFCO) is one of the most effective catalysts for oxygen evolution reaction (OER), comparable with noble metal oxides. In this study, crystalline CFCO ultrasmall particles with nanometric dimension are synthesized by a reverse micelle method on TiO 2 nanoparticles. The particle size decreases with decreasing molar ratio of water to surfactant. The precursors of CFCO must be calcined after loading on TiO 2 nanoparticles to achieve CFCO ultrasmall particles with several nanometers in size. Interaction between the precursors and TiO 2 is speculated to suppress aggregation of the precursors during calcination. The photocatalytic activity...
