Mai-Anh Ha

Researcher III-Computational Science


Mai-Anh Ha has expertise in electronic structure studies of catalysis, with publications and manuscripts spanning a range of topics; catalytic processes on supported clusters; boration reaction mechanisms; dehydrogenation as a function of cluster size; stability of layered materials (platinum skins atop platinum-nickel alloys, iridium oxide skins on iridium facets); and, most recently, facet dependence on water-splitting reactions. The broad range of structural morphologies and catalyst chemistries Ha has examined has allowed NREL to predict the catalytic activity of fuel cell and electrolyzer reactions on various catalysts with experimental validation of predicted activities under application-relevant conditions.
