An Electrochromic Ag-Decorated WO_3-x Film with Adjustable Defect States for Electrochemical Surface-Enhanced Raman Spectroscopy.

ABSTRACT: Electrochemical surface-enhanced Raman scattering (EC-SERS) spectroscopy is an ultrasensitive spectro-electrochemistry technique that provides mechanistic and dynamic information on electrochemical interfaces at the molecular level. However, the plasmon-mediated photocatalysis hinders the intrinsic electrochemical behavior of molecules at electrochemical interfaces. This work aimed to develop a facile method for constructing a reliable EC-SERS substrate that can be used to study the molecular dynamics at electrochemical interfaces. Herein, a novel Ag-WO_3-x electrochromic heterostructure was synthesized for EC-SERS. Especially, the use of electrochromic WO_3-x film suppresses the influence of hot-electrons-induced catalysis while offering a reliable SERS effect. Based o
