Fe3O4/carbon quantum dots hybrid nanoflowers for highly active and recyclable visible-light driven photocatalyst

Abstract

Water dispersible Fe₃O₄@carbon quantum dots (CQDs) hybrid nanoflowers show highly efficient photocatalytic activities because of their strong absorption in the visible light range and upconversion photoluminescence. The magnetic Fe₃O₄ nanocrystals not only allow efficient magnetic separation and recycling of the photocatalyst, but also promote the photocatalytic activities of the CQDs.
