Facile and rapid growth of Ag2S microrod arrays as efficient substrates for both SERS detection and photocatalytic degradation of organic dyes.

A novel bifunctional substrate derived from well-aligned Ag2S microrod arrays was obtained via a facile and cost-effective solvothermal process rapidly within 1 h. It demonstrates great activity for both SERS detection and photocatalytic degradation of organic dyes, and thus holds great potential for environmental monitoring devices and other applications.
