“…The large amount of ferromagnetic Fe dopant in the present compound and the dominance of the twofold exchange contact between the ferromagnetic cations (Fe/Mn 3+ -O-Fe/Mn 4+ ) confirm the ferromagnetic property of CBFMO double perovskite. 72 The ferromagnetic functionality of the material is demonstrated by the hysteresis loop, where the remnant magnetization (M r ) is found to be 0.149 emu g À1 . However, the saturation magnetization (M s ) value is not evident from the figure.…”

“…The radius of the A ions is larger than that of B metal ions [ 98 , 99 , 100 ]. Single perovskite is used in many different applications, such as gas permeation membranes, metal–air batteries, magnetic devices, and heterogeneous catalysis [ 101 , 102 ]. However, single perovskite may not provide sufficient stability or performance.…”

The many pollutants detected in water represent a global environmental issue. Emerging and persistent organic pollutants are particularly difficult to remove using traditional treatment methods. Electro-oxidation and sulfate-radical-based advanced oxidation processes are innovative removal methods for these contaminants. These approaches rely on the generation of hydroxyl and sulfate radicals during electro-oxidation and sulfate activation, respectively. In addition, hybrid activation, in which these methods are combined, is interesting because of the synergistic effect of hydroxyl and sulfate radicals. Hybrid activation effectiveness in pollutant removal can be influenced by various factors, particularly the materials used for the anode. This review focuses on various organic pollutants. However, it focuses more on pharmaceutical pollutants, particularly paracetamol, as this is the most frequently detected emerging pollutant. It then discusses electro-oxidation, photocatalysis and sulfate radicals, highlighting their unique advantages and their performance for water treatment. It focuses on perovskite oxides as an anode material, with a particular interest in calcium copper titanate (CCTO), due to its unique properties. The review describes different CCTO synthesis techniques, modifications, and applications for water remediation.

Herein, a series of perovskite‐type hydride materials RMnH3 (R = Ca, Sr, and Ba) are investigated by density functional theory for solid‐state hydrogen storage. Their structural, mechanical, electronic, and optical properties are calculated and their thermodynamic, dynamic, and mechanical stability is assessed. All compounds crystallize in the undistorted cubic perovskite system with the Pm‐3m symmetry. The results from mechanical properties, based on parameters such as Poisson's ratio (ν) and the G/B ratio, indicate that CaMnH3 and SrMnH3 exhibit brittle behavior, primarily attributed to the dominance of ionic bonds, while BaMnH3 is distinguished by its ductility, resulting from a prevalence of covalent bonds. Additionally, the electronic structure analysis reveals that all examined hydrides possess metallic behavior. Further calculations of the optical properties are also performed, providing supplementary insights into the physical features of the hydrides. The gravimetric hydrogen storage capacities (Cwt%) are calculated, with values of 2.96 wt% for CaMnH3, 2.019 wt% for SrMnH3, and 1.513 wt% for BaMnH3, accompanied by respective desorption temperatures of 214.83, 193.42, and 145.43 K. Overall, these results highlight the potential of perovskite hydrides RMnH3 as promising materials for hydrogen storage applications, significantly contributing to a sustainable energy future.
