摘要：
Amicrosphere-shaped CuS/Ag2S nanocomposites were synthesized by hydrothermal method. The morphology and optical properties of CuS/Ag2S nanocomposites were characterized by transmission electron microscopy, UV-Vis absorption spectroscopy, and Raman spectroscopy. The peroxidase-like properties were investigated, and peroxidase-like reactions catalyzed by CuS/Ag2S nanocomposite were detected by surface-enhanced Raman scattering in situ. The colorimetric reaction was performed using 3, 3', 5, 5'-tetramethyl-benzidine (TMB) as a substrate, and it was proved that CuS/Ag2S nanocomposite has peroxidation-like properties in the presence of hydrogen peroxide( H2O2) which can oxidize colorless TMB to blue oxTMB. And the detection of H2O2 are realized.
