pentlandite; hydrogen evolution reaction

Abstract
We herein present a series of hitherto unprecedented seleno-pentlandites (Fe4.5Ni4.5S8−YSeY). By analysing the influence of S/Se exchange on the catalyst structure and activity in the electrochemical hydrogen evolution reaction we herein showcase the potential and limitations of homologous S/Se exchanges within pentlandite HER catalysts.
