“…However, the less intense peak of Ti 3+ (2p 3/2 ) core levels proves the minor presence of Ti 3+ cations. The peak separation of 5.6 eV between the Ti(2p 3/2 ) and Ti(2p 1/2 ) core levels suggest Ti 4+ cations [ 18 , 19 , 31 ]. The compound peak characteristic for O(1s) XPS spectrum deconvoluted using Voigt fitting function ( Figure 3 (c)) revealed 2 peaks at a binding energy of 529.5 and 531.1 eV.…”

“…Moreover, perovskite oxides are contemplated to be an exhilarating group of visible-light photocatalytic materials in current times [ 16 ]. Perovskite oxides delivered excellent structural stability and flexibility to accommodate a wide range of cations with different oxidation states, which guided them for excellent catalytic activity and consequently for applications in photocatalysis [ 17 , 18 , 19 , 20 , 21 ]. Various research groups have explored the photocatalytic dye degradation activities of the perovskite materials such as ZnTiO 3 , SrTiO 3 , BaTiO 3 , NiTiO 3 , CoTiO 3 , and MnTiO 3 , respectively [ 20 , 22 , 23 , 24 , 25 , 26 ].…”

MTO nanodiscs synthesized using the hydrothermal approach were explored for the photocatalytic removal of methylene blue (MB), rhodamine B (RhB), congo red (CR), and methyl orange (MO). The disc-like structures of ~16 nm thick and ~291 nm average diameter of stoichiometric MTO were rhombohedral in nature. The MTO nanodiscs delivered stable and recyclable photocatalytic activity under Xe lamp irradiation. The kinetic studies showed the 89.7, 80.4, 79.4, and 79.4 % degradation of MB, RhB, MO, and CR at the rate constants of 0.011(±0.001), 0.006(±0.001), 0.007(±0.0007), and 0.009 (±0.0001) min −1 , respectively, after the 180 min of irradiation. The substantial function of photogenerated holes and hydroxide radicals pertaining to the dye removal phenomena is confirmed by radical scavenger trapping studies. Overall, the present studies provide a way to develop pristine and heterostructure perovskite for photocatalysts degradation of various organic wastes.

“…Subsequently, Zhang et al reported that the Na and Bi cations were simultaneously doped into the A site of SrTiO 3 to reduce the potential polarization of SCs. ,, However, the stability of SrTiO 3 modified by heteroatom doping needs to be intensely considered, despite its good prospects in dielectric materials. Considering the ultrahigh capacitance of NiO, Kitchamsetti et al synthesized the mesoporous NiTiO 3 rods as an electrode for SCs, revealing the capacitance of 542.26 F g –1 in KOH electrolytes, owing to the rapid interfacial reaction …”

Perovskite oxides, with the general formula of ABO 3 , are considered as one of the promising candidates of electroactive materials for supercapacitors (SCs) as a result of their stable structure, rich oxygen vacancies, and highly reversible redox capability. According to the oxygen ion intercalation mechanism, the concentration of oxygen vacancy in perovskite oxides is proportional to the capacitance of SCs. Meanwhile, various strategies, e.g., doping, compositing, and specific synthesis processes, are proposed to increase the capacitance for perovskite oxide electrodes. Herein, this review mainly emphasizes the relationship between the energy storage mechanism and the key role of oxygen vacancies in perovskite. In terms of structural design, preparation methods, and various approaches to improve the electrochemical performance of the latest reported perovskite-type oxides for SCs, we give a detailed discussion and summarize the characteristics of them, which is expected to have impact on the fields of perovskite oxide science. Furthermore, we pointed out the challenges and perspectives of perovskite-oxide-based SCs.

“…Kitchamsetti et al, [ 165 ] used meso porous interlocked nickel titanate (NTO) rod-based perovskite for fascinating materials in a supercapacitor application, and showed a unique rod morphology and significantly better capacitance properties (542.26 F g −1 ) with better cyclic stability (2100 cycles). Using cyclic voltammetry and the charge–discharge method, Pious et al [ 166 ] prepared an 0D (CH 3 NH 3 ) 3 Bi 2 I 9 lead-free thin-film electrode as a potential perovskite electrode material for electrochemical double-layer capacitors (EDLC).…”
