Broadband photocatalysis using a Z-scheme heterojunction of Au/NaYF4:Yb,Er/WO3·0.33H2O-W18O49via a synergetic strategy of upconversion function and plasmonic effect

Employing upconversion hosts and plasmonic Au, this work deals with the synthesis of a novel heterojunction via a hydrothermal followed by a photo-reduction method.
