We present a novel method for the synthesis of nanosize CdS particles with a silk fibroin membrane, which were characterized with UV spectrometry, X‐ray diffraction (XRD), and atomic force microscopy. The UV spectra showed a clear blueshift in the absorption edge for the CdS particles prepared at different concentrations. XRD showed the prevailing crystal were the cube ZnS crystals formed. The particle sizes were calculated from the band gaps with the effective mass approximate model, suggesting that they were dependent on the concentration of the precursors. Meanwhile, nanosize CdS had good photocatalytic activity throughout the photocatalytic degradation experiments. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 2162–2166, 2006
