Development of clean and sustainable renewable energy sources is imperative to deal with the future energy crises. Various technologies have been developed in this context, for example, water electrolysis, reversible fuel cell and metal-air batteries etc. However, the sluggish kinetics of oxygen evolution reaction (OER) occurring at the anode of these energy storage/conversion systems becomes a significant hurdle. Recently, researchers utilized noble metals as electrocatalysts to enhance their efficiency still the high cost and scarcity of these materials draw the attention of researchers towards the costeffective Perovskite oxide nanomaterials due to their extraordinary flexibility. In this review, the importance of perovskite oxide nanomaterials as electrocatalysts for OER is discussed, followed by related reaction mechanisms and series of activity descriptors. Fundamental understanding about the instrumentation, parameters and protocols for the experimental measurements including concerned issues are also summarized. Moreover, various activation strategies adopted in recent years to enhance the electrocatalytic performance of perovskite oxides are also underlined. The article concludes with an outlook of existing challenges and future scope of these materials as electrocatalysts. The challenges and prospects discussed herein may pave the ways to rationally design the highly active and stable perovskites to outperform noble metal-based OER electrocatalysts.

“…Therefore, Li–air batteries require an extra-sophisticated water-proof layer to protect the anode active materials which would add to the complexity of these batteries. , Therefore, metal–air batteries other than Li–air are explored to a greater extent. In this regard, Al–air, Zn–air, and to some extent Na–air batteries (under nonaqueous) are considered as potential candidates considering their low cost owing to abundant raw materials. − As far as nonaqueous batteries are concerned, a Na–air battery could provide an output energy density of about 1600 Wh kg –1 . However, both Na–air and Li–air systems use nonaqueous electrolytes because of their reactivities with air, moisture, and water.…”

“…However, in selected cases, very thin monolayers can be used to stabilize the cathode–electrolyte interface in solid-state batteries. Nevertheless, a good number of high-performance bifunctional electrocatalysts have been developed for the cathode recently. ,,,, However, they cannot continue their good activity and stability if the cycle period is over 2 h at higher current density (typically ∼20 mA cm –2 or higher). A tough problem is the degradation of most OER catalysts including IrO 2 and RuO 2 catalysts, especially under high current densities.…”

Surface states of solids provide a unique way to graft organic molecules into monolayers by simple dip chemistry. Such interfaces can be highly functional and serve as a foundation for the formation of precisely controlled nanostructures of other materials via atomic/molecular diffusion, adsorption, and growth. The coverage, orientation, consistency, and functionality of these monolayers can be easily tailored to create technologically important materials. On the other hand, research on batteries has skyrocketed in recent times due to a paradigm shift toward nonconventional energy resources and the pledge of the transport sector to go soon all electric. Therefore, meeting energy demands by coping with global climate protocols is important for sustainable development. In this regard, the fabrication of efficient, stable, and long-lasting electrodes for lithium as well as nonlithium batteries is needed. However, they suffer from several electrode issues which ultimately limit their storage capacity and cycle life. Recently, there has been a scientific trend to incorporate suitably chosen organic monolayers for controlled syntheses of active materials that are highly catalytic and functional to improve the performances of metal–air and other batteries. Moreover, molecular surface modification techniques have been commercially adopted for corrosion inhibition, moletronics, surface activation/protection, etc. Looking at the resurgence of molecular engineering and unconventional energy storage systems in recent times, it is necessary to bring molecular dynamics and versatility in designing novel electrode materials. This review intends to increase the attention to address the challenges of battery electrodes using cutting-edge surface chemistry and molecular engineering techniques by providing critical insights on molecular monolayers for the development of futuristic metal–air batteries.

“…To date, most perovskite oxide composites have been reported with conductive carbon-based support materials, such as graphene, carbon black, carbon nanotubes, acetylene black, Vulcan carbon, etc. − However, these carbon-based materials are not suitable for long-term stability because of the occurrence of electrochemical corrosion under a high oxidative potential, leading to a reduction in the number of active sites. However, the successful synthesis of perovskite composites with other OER active electrocatalysts encounters the difficulty of forming secondary phases and rationally controlling the composition.…”

It is essential to design high-efficiency, stable, and inexpensive electrocatalysts for the oxygen evolution reaction (OER). We fabricate a hybrid system of perovskite LaCoO 3 with spinel NiCo 2 O 4 denoted LaCoO 3 /NiCo 2 O 4 via an in situ hydrothermal process. In situ incorporation of LaCoO 3 nanoparticles on the NiCo 2 O 4 nanoflower surface is confirmed by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) images. Benefiting from the interface engineering, the obtained LaCoO 3 / NiCo 2 O 4 hybrid nanoflowers exhibit the lowest overpotential of 353 at a current density of 10 mA/cm 2 and a small Tafel slope of 59 mV/dec in alkaline media compared with pristine LaCoO 3 (401 mV, 116 mV/dec) and NiCo 2 O 4 (386 mV, 73 mV/dec). The optimized sample possesses a higher electrochemical surface of 111.45 cm 2 than LaCoO 3 perovskite (35.37 cm 2 ) and NiCo 2 O 4 spinel oxide (61.37 cm 2 ) structures. The enhanced OER performance of the LaCoO 3 /NiCo 2 O 4 composite structure is due to the accumulation of LaCoO 3 nanoparticles over NiCo 2 O 4 petals, which introduces a substantial number of electrochemically active sites for the catalysis process to promote charge and mass transport. In addition to this, LaCoO 3 / NiCo 2 O 4 exhibits long-term stability over 20 h. Thus, it is believed that the excellent OER activity of the LaCoO 3 /NiCo 2 O 4 composite structure is associated with strong interaction between LaCoO 3 and NiCo 2 O 4 as well as a large surface area and a unique flower structure.
