摘要：Plasmonic MoO3-x@MoO3 nanosheets obtained from surface oxidation of MoO3-x were employed as a SERS substrate for methylene blue detection. They exhibit extraordinary sensitivity comparable to noble metals, which is attributed to shell-isolated electromagnetic enhancing by the plasmonic MoO3-x core and elimination of the photocatalytic degradation by the MoO3 shell.
