Abstract
Ultrathin ZIF-8 wrapping was constructed on Au-dotted Ag-nanowires to obtain Ag@Au@ZIF-8. A thin film (Ag@Au@ZIF-8 NWs/TF) was constructed to selectively adsorb and enrich CO2 molecules, which solved the problem that SERS signals could not be detected due to the poor affinity of the metal surface and the low concentration of gas molecules.
