High-Efficiency of Bi-Functional-Based Perovskite Nanocomposite for Oxygen Evolution and Oxygen Reduction Reaction: An Overview

Abstract

High efficient, low-cost and environmentally friendly-natured bi-functional-based perovskite electrode catalysts (BFPEC) are receiving increasing attention for oxygen reduction/oxygen evolution reaction (ORR/OER), playing an important role in the electrochemical energy conversion process using fuel cells and rechargeable batteries. Herein, we highlighted the different kinds of synthesis routes, morphological studies and electrode catalysts with A-site and B-site substitution co-substitution, generating oxygen vacancies studies for boosting ORR and OER activities. However, perovskite is a novel type of oxide family, which shows the state-of-art electrocatalytic performances in energy storage device applications. In this review article, we go through different types of BFPECs that have received massive appreciation and various strategies to promote their electrocatalytic activities (ORR/OER). Based on these various properties and their applications of BFPEC for ORR/OER, the general mechanism, catalytic performance and future outlook of these electrode catalysts have also been discussed.

Recent progress in ZnCo2O4 and its composites for energy storage and conversion: a review

“…As mentioned in the previous topic, both oxygen reduction/oxygen evolution reactions (ORR/OER) play an important role in the electrochemical energy conversion process, not only metal-air rechargeable batteries but also in fuel cells 260 . In fact, because of high associated activation energies, such reactions are usually sluggish and require catalysts to enhance the kinetics 213 .…”

“…In fact, because of high associated activation energies, such reactions are usually sluggish and require catalysts to enhance the kinetics 213 . In this sense, great efforts have been directed towards the development of inexpensive, efficient, noble metal-free and stable electrocatalysts for next-generation sustainable energy technologies 260 . Thereby, ZnCo2O4 and their composites show great potential as electrocatalysts due to their high intrinsic activity 261 , and in many cases exhibiting both ORR and OER activity simultaneously.…”

Recent Progress in the Development of Advanced Functionalized Electrodes for Oxygen Evolution Reaction: An Overview

“…The prepared LNMO NFs had more OER and ORR activity than LaNiO 3 , as well as a higher positive half-wave potential (0.63 V) and a lower overpotential of 0.45 V at a current density of 10 mA cm −2 . Because the LNMO has a strong oxygen-binding surface that enhances OER activity, it could be employed as a promising bifunctional catalyst for zinc-air battery applications [ 97 ]. Exploration of non-noble metals and high-activity electrocatalysts via simple and controlled techniques continues to be a significant problem for zinc-air batteries.…”

Effect of calcium doping on the electrocatalytic activity of the Bi1−xCaxFeO3−δ oxygen electrode for solid oxide fuel cells

“…[3][4][5] In recent years, some efforts have been devoted to bismuth ferrite oxide (BiFeO 3 , BFO) with low thermal expansion coefficient and excellent chemical compatibility, giving rise to efficient utilizations for the ORR and oxygen evolution reaction (OER). [6][7][8] Nevertheless, a secondary phase appears in BFO at 447-767 °C, which limits its practical applications. 9 Thus, improving thermodynamic stability is considered to be crucial to the BFO catalyst.…”
