DOI: 10.1002/smtd.202101328
Abstract: Development of efficient electrocatalysts usually relies on half‐cell electrochemical tests for rapid material screening, which however are not always consistent with the associated full cell evaluation. This study designs a tensile‐strained Pd anode and reveals… read more here.
