Advancements in two-dimensional covalent organic framework nanosheets for electrocatalytic energy conversion: current and future prospects

“…Research pertaining to hydrogen storage and production using various methods is currently being conducted. In particular, a method for generating hydrogen by decomposing water via an electrochemical method is receiving attention because it requires a precursor other than water; this is referred to as the HER [105] . Rare or transition metals (Pt, Pd, Ru, Co, etc.)…”

Advances in the mechanism investigation for the oxygen evolution reaction: fundamental theory and monitoring techniques

“…7 The complexity of the OER adds significant overpotential to the realistic water splitting procedure, resulting in sluggish reaction kinetics. [8][9][10][11][12] With the aim of significantly reducing the reaction overpotential, several studies have been published focusing on powerful OER electrocatalysts with different composites and structures [13][14][15][16][17][18][19][20][21][22][23][24][25][26] such as noble metals, metal single-atoms, 27,28 layered double hydroxides (LDHs), and metal oxides or chalcogenides. 29,30 The exploration and development of the best-fit catalysts depend critically on a thorough knowledge of the fundamental catalytic mechanisms, which necessitates the mapping of actual reaction pathways.…”

RuSe2 and CoSe2 Nanoparticles Incorporated Nitrogen-Doped Carbon as Efficient Trifunctional Electrocatalyst for Zinc–Air Batteries and Water Splitting

“…The rising consumption of fossil fuels has led to global energy shortages and air pollution, making the adoption of renewable energy solutions vital for addressing the energy crisis. Recently, there has been a growing focus on electrochemical energy devices including fuel cells, metal–air cells, and water electrolyzers. − However, the practical application of these technologies are greatly restricted due to inefficient electrocatalytic reactions, such as oxygen reduction/evolution reactions (ORR/OER), hydrogen evolution reactions (HER), etc. − Therefore, it is crucial to develop effective electrocatalysts tailored for the aforementioned electrocatalytic processes. In general, noble metal based electrocatalysts (Pt, RuO 2 ) possess satisfactory electrocatalytic properties (ORR half-wave potential >0.85 V and OER/HER overpotential <300/50 mV at a current density of 10 mA·cm –2 ). − Unfortunately, the widespread utilization of these precious metals is constrained by their high costs and insufficient production. ,, Multifunctional electrocatalysts enable multiple electrocatalytic processes to be implemented in the same energy conversion device, which helps to simplify the system structure and ultimately reduces costs. , As a result, it is important to develop low-cost and high-performance multifunctional electrocatalysts to promote the widespread application of metal–air batteries and water electrolyzers.…”
