Multifunctional Ag2S-Ag heterogeneous porous nanorods were synthesised by the irradiation of microwave in 210s .The nanorods were characterized by scanning electron microscopic (SEM) and X-ray diffraction (XRD). The photocatalytic activity for degradation of crystal violet and the lowest detectable limit of crystal violet are tested. Results show that the degradation rate of crystal violet can reach almost 100% within 50 min, the detection limit of crystal violet as low as 1×10-6 M. They indicate that the Ag2S-Ag heterogeneous porous nanorods would be a promising material for environmental protection.
