“…LaFeO 3 is photocatalytic active in visible-light due to its unique optoelectronic properties and narrow bandgap [13,14]. Tijare et al [15] found that Pt/LaFeO 3 exhibited hydrogen generation through sacrificial donor assisted photocatalytic water splitting. CuO x and Cu [16] have both been frequently studied as efficient and economically feasible cocatalysts for TiO 2 to facilitate the charge-separation process and thus enhance the activity of the photocatalytic H 2 production.…”

“…The LaFeO 3 has received considerable attention because of its strong photocatalytic activity [15][16][17][18]. It was found that the structures and properties of the materials were highly dependent on synthesis process of its precursor powders, so the improvement of preparation method of these powders is paid much attention by researchers [19].…”

LaFeO 3 nanospheres were synthesized by hydrothermal method followed by calcination. Citric acid was found to be key factor to the purity and the surface morphology of the LaFeO 3 nanospheres. The obtained nanospheres have been structurally characterized by XRD which confirms the single crystalline orthorhombic structure. The structural information of the nanosphere was also confirmed from the Raman spectrum. HRSEM and AFM revealed that the prepared sample has been composed of spherical like morphology with an average size of about 45 nm. From XPS analysis, the chemical state of the LaFeO 3 nanospheres was confirmed. Magnetic measurement indicates the products shows weak magnetic behaviour. The UV-Vis spectroscopy analysis shows strong absorption at 466 nm which confirms that the obtained material has excellent visible light absorption ability. Furthermore, the photocatalytic experiment demonstrates that the prepared LaFeO 3 nanospheres exhibit well and stable photocatalytic activity for decomposition of methyl orange under visible-light irradiation.

“…Performance and hydrogen absorption mechanisms of rare-earth perovskite-type electrode materials in Ni/MH batteries RE-perovskite ABO 3 oxides are known to show catalytic behavior in hydrogen-rich media [72,73], thus it is not a surprise that these materials can be useful for hydrogen storage. Their application to hydrogen batteries is based on the advantages shown in the catalysis and ionic conduction fields.…”

Rare-earth perovskites-type oxides are compounds with the general formula ABO 3 . There are many industrial and research applications related to their properties such as photocatalytic activity, magnetism, or pyroferro and piezo-electricity, and interest in these compounds in the field of energy storage and conversion is growing. Rare-earth perovskite-type oxides may be used in nickelmetal hydride (Ni/MH) battery technology because these materials may store hydrogen in strong alkaline environments, and also because of their abundance and low cost. In this review, the use of rare-earth perovskite-type oxides in Ni/MH batteries is described, starting from their crystalline structure and production methods. In each category, a description concerning the latest advances and future research direction is presented. Electrochemical performance of the perovskite-type electrodes is reviewed extensively. In addition, various strategies for enhancing their hydrogen storage capacity as a negative electrode in hydrogen batteries are discussed. Drawbacks and challenges of this technology are also presented.
