- Traditionally, catalysts for splitting water involve expensive precious metals such as iridium oxide, ruthenium oxide and platinum,”
- “An additional problem has been stability, especially for the oxygen evolution part of the process.
- “What we have found is that we can use two earth-abundant cheaper alternatives—cobalt and nickel oxide with only a fraction of gold nanoparticles – to create a stable catalyst to split water and produce hydrogen without emissions. “
- From an industry point of view, it makes a lot of sense to use one catalyst material instead of two different catalysts to produce hydrogen from water.”
-
- the stored hydrogen could then be used in fuel cells.
- “Fuel cells are a mature technology, already being rolled out in many makes of vehicle. They use hydrogen and oxygen as fuels to generate electricity – essentially the opposite of water splitting.
- “With a lot of cheaply ‘made’ hydrogen we can feed fuel cell-generated electricity back into the grid when required during peak demand or power our transportation system and the only thing emitted is water.”
- “Gold Doping in a Layered Co-Ni Hydroxide System via Galvanic Replacement for Overall Electrochemical” was published in Advanced Functional Materials.
- cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.
- the potential for the chemical storage of renewable energy in the form of hydrogen was being investigated around the world.
- “In principle, hydrogen offers a way to store clean energy .
- “current methods that use carbon sources to produce hydrogen emit carbon dioxide, a greenhouse gas that mitigates the benefits of using renewable energy from the sun and wind.
- electrochemical water splitting into hydrogen and oxygen using cheap and readily available elements as catalysts.
