The development of high‐performance transition metal−based electrocatalysts for the oxygen evolution reaction (OER) is paramount for electrochemical secondary metal‐air batteries and water splitting. Two‐dimensional (2D) metal‐organic framework (MOF) nanosheets have recently emerged as a novel class of efficient electrocatalysts for OER, due to a high specific surface area, ultrasmall thickness and abundance of active sites. Here, we summarize recent progress in the preparation and characterization of 2D transition metal−based MOFs (e. g. Ni, Co and Cu), as well as their composites and derivatives, including metals/alloys, metal oxides/chalcogenides and metal phosphides/hydroxides, as OER electrocatalysts reported over the past several years. Design principles and preparation routes are presented. The performance of the electrocatalysts is directly compared in terms of overpotential (η) (thermodynamics) and electrocatalytic current density (kinetics), as well as operational stability (economics). Many of these materials exhibit superior catalytic activity compared to the noble metal−based catalysts such as RuO2 (η<300 mV at 10 mA cm−2), and considerable stability with negligible decay with operation over several hours to days. Challenges and perspectives of applying 2D MOFs and their derivatives for OER electrocatalysis are also discussed.

The attention to renewable materials is amazingly increased in recent years to decrease environmental pollutions. Zea mays (corn) is one of the most produced plants by humans to provide food and energy. Hence, corn wastes as abundant and low-cost biomass are easily found throughout the world. Tremendous efforts have been accomplished in recent years to fabricate electrochemical energy storage devices (EES) from renewable biomass materials because of increasing attention to the environment. All main parts of EES devices include electrodes, binder, electrolyte, and membrane (separator) can be produced via corn waste biochar and corn derivatives. The low-cost corn-based EES devices not only decrease environmental pollution but also have significant electrochemical properties include specific capacitance and electrochemical durability. This review investigates state-of-the-art development in the corn-based EES devices.

The fast growth in human population and the quick cultural advancement of human society leads to the tremendous increase in energy demand. [1] During the past, fossil fuels were used as the main energy sources, while their excessive use based on the conventional combustion technology releases excessive greenhouse gases into the environment, causing adverse impact on the sustainability of ecosystem. To cope with the challenges of stringent environmental legislations and the reliance on fossil fuels, renewable Secondary Zn-air batteries (ZABs) are recognized as one of the most promising power sources for the future with lucrative features of low cost, high energy density, eco-friendliness, and high safety. However, the widespread implementation of ZABs is still hampered by the sluggish oxygen redox reactions. Thus the deployment of cost-effective and highly efficient air electrodes to substitute precious metals (Pt/Ir), is highly challenging, however, highly desired. Zeolitic imidazolate frameworks (ZIFs) are emerging functional materials, which demonstrate several outstanding characteristics, such as high specific surface area, high conductivity, self-doped N, open pore structure, versatile compositions and favourable chemical stability. Through varying the metal/organic moiety or by employing different synthesis protocols, ZIFs with different properties could be obtained. Being adaptable, desired functionalities may be further incorporated into ZIFs through pre-treatment, in situ treatment, and post treatment. Thus, ZIFs are the ideal precursors for the preparation of variety of bi-functional air electrodes for ZABs by materials tuning, morphological control, or by materials hybridization. Here, the recent advances of ZIFs-based materials are critically surveyed from the perspective of synthesis, morphology, structure and properties, and correlated with performance indicators of ZABs. Finally, the major challenges and future prospects of ZIFs associated with ZABs are discussed.
