Abstract

In the present work, flower-like Cu₂SrSnS₄ (CSTS) sample is successfully prepared by solvothermal method. The XRD and Raman analysis confirm that pure CSTS phase with trigonal structure is obtained. The band gap of as-obtained CSTS naocrystals is estimated to be 1.49eV. The removal of methylene blue (MB) within 100min under simulated solar light irradiation is around 90%, depicting that CSTS is a potential material for effective solar light photocatalytic application. Meanwhile, The Seebeck coefficient and electrical conductivity of CSTS material can reach to 128.57μV•K^-1 and 20.35S·m^-1 at 675K, respectively, indicating its potential for thermoelectric application.
