A novel monoclinic metal oxide catalyst for oxygen evolution reactions in alkaline media

Abstract

The main bottleneck of electrolytic water for hydrogen production in alkaline media is the oxygen evolution reaction (OER) involving four-electron transfer. Designing highly efficient OER catalysts is attractive to accelerate...

Mesoporous Mn–Fe oxyhydroxides for oxygen evolution

“…17 Therefore, the development of Earth-abundant and inexpensive transition-metal oxyhydroxides is highly desirable for water splitting application. 18,19 Manganese is the third most abundant transition metal in the crust of the Earth, which has a much lower price than cobalt and nickel. 20 In addition, manganese has excellent redox properties, which make it have good electrocatalytic application potential.…”

“…1,11 Currently, precious metals like Ir-or Ru-based oxides are used as electrocatalysts for the oxygen evolution reaction (OER) but their high cost and low abundance hinder their large-scale application. 12,13 In addition to the high cost, the sluggish fourelectron transfer kinetics involved in the OER compels researchers to develop highly efficient and cost-effective electrocatalysts for upgrading the energy conversion technologies. 14 Several research studies, based on these aspects, envisaged that 3d-transition metal-based (e.g.…”

Improved Catalytic Activity and Stability of Co9S8 by Se Incorporation for Efficient Oxygen Evolution Reaction

“…Electrocatalytic water splitting is a promising sustainable energy production technology, effectively alleviating the temporal and spatial discontinuities of natural friendly energy such as tidal energy, wind energy, and solar energy to a certain extent. − Typically, oxygen evolution reaction (OER) occurs at the anode with a four-electron-transfer process, leading to O–H bond breaking and O–O bond formation. , Therefore, OER limits the large-scale development of water splitting due to the sluggish four-electron-transfer process. , Precious metal catalysts (such as RuO 2 and IrO 2 ) are recognized as excellent OER catalysts. − Nevertheless, their low reserves and high cost limit large-scale commercial applications. , Therefore, the search and development of efficient and robust electrocatalysts with low energy barriers for OER and efficient water electrolysis conversion are critical for building future clean/sustainable energy systems …”
