Better living through water-splitting Chemists have known how to use electricity split water into hydrogen and oxygen for more than 200 years. Nonetheless, because the electrochemical route is inefficient, most of made nowadays comes from natural gas. Seh et al. review recent progress in electrocatalyst development accelerate water-splitting, reverse reactions that underlie fuel cells, related oxygen, nitrogen, carbon dioxide reductions. A unified theoretical framework highlights need catalyst design strategies selectively stabilize distinct reaction intermediates relative each other. Science , this issue p. 10.1126/science.aad4998

A highly active and stable IrO _x /SrIrO ₃ catalyst for the oxygen evolution reaction

Science, Год журнала: 2016, Номер 353(6303), С. 1011 - 1014

Опубликована: Сен. 1, 2016

Oxygen electrochemistry plays a key role in renewable energy technologies such as fuel cells and electrolyzers, but the slow kinetics of oxygen evolution reaction (OER) limit performance commercialization devices. Here we report an iridium oxide/strontium oxide (IrO x /SrIrO 3 ) catalyst formed during electrochemical testing by strontium leaching from surface layers thin films SrIrO . This has demonstrated specific activity at 10 milliamps per square centimeter (OER current normalized to area), with only 270 290 millivolts overpotential for 30 hours continuous acidic electrolyte. Density functional theory calculations suggest formation highly active IrO or anatase 2 motifs. The outperforms known ruthenium (RuO systems, other OER catalysts that have reasonable

Transition‐Metal (Co, Ni, and Fe)‐Based Electrocatalysts for the Water Oxidation Reaction

Advanced Materials, Год журнала: 2016, Номер 28(42), С. 9266 - 9291

Опубликована: Авг. 29, 2016

Increasing energy demands and environment awareness have promoted extensive research on the development of alternative conversion storage technologies with high efficiency environmental friendliness. Among them, water splitting is very appealing, receiving more attention. The critical challenge this renewable-energy technology to expedite oxygen evolution reaction (OER) because its slow kinetics large overpotential. Therefore, developing efficient electrocatalysts catalytic activities great importance for high-performance splitting. In past few years, much effort has been devoted OER based transition-metal elements that are low-cost, highly efficient, excellent stability. Here, recent progress design, synthesis, application elements, including Co, Ni, Fe, summarized, some invigorating perspectives future developments provided.
