Single yttrium sites on carbon-coated TiO2 for efficient electrocatalytic N2 reduction†
Abstract
We report single yttrium sites anchored on carbon-coated TiO2 for efficient and stable electrocatalytic N2 fixation, delivering an NH3 faradaic efficiency exceeding 11.0% and an NH3 yield rate as high as 6.3 μgNH3 h−1 mgcat.−1 at low overpotentials, thus surpassing many reported metal electrocatalysts.
