Abstract:

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.

Key words: Nanocomposite, Peroxidase-like, Raman spectroscopy, H2O2
