A Tohoku University group of researchers have unraveled the mysteries behind a recently identified material – zirconium nitride ZrN – that helps power clean energy reactions. Their proposed framework will help future designs for transition metal nitrides, paving a path for generating cleaner energy. The study was published in the journal Chemical Science, where was it featured as the front cover article.
C are devices that use hydrogen and oxygen to make clean electricity through chemical reactions, specifically the hydrogen oxidation reaction and the oxygen reduction reaction ORR. Cs, with their ability to operate in alkaline conditions, provide a suitable environment for earth-based catalysts, offering a cheaper alternative to other efficient catalyst materials, such as platinum. Recent studies have shown that ZrN exhibits efficient performances – even outperforming platinum – when used for the ORR in alkaline media. ZrN, whilst not an earth-abundant material, is still more cost-effective than alternatives.
