Engineering large-scaled electrochromic semiconductor films as reproductive SERS substrates for operando investigation at the solid/liquid interfaces
文献摘要：
Although surface-enhanced Raman spectroscopy(SERS)has been applied for gathering fingerprint infor-mation,even in single molecule analysis,the decayed Raman signals in aqueous solutions largely ob-struct the on-site insight reaction process.In this study,large-scaled semiconductor films with multi-walled(TiO2/WO3/TiO2)nanopore distribution are fabricated by combining electrochemical anodization and sputtering technique,and then employed as the SERS substrates for detection of molecules at the solid/liquid interfaces.Given the remarkably improved electrochromic property of the multi-walled film,such SERS substrates were endowed with tunable oxygen vacancy(Vo)density and distribution via sim-ply applying electrochemical bias voltage,which enabled one to achieve an enhanced charge transfer efficiency and thus a remarkably increased Raman signal even in solution.The Vo-rich SERS substrate is highly repeatable,thus providing a reliable platform for in-situ monitoring of the target molecules or intermediates at the solid/liquid interfaces.
