摘      要：Low dimension nano photocatalysts show great potential in the field of treating contaminated water for their large surface area and size *** this study,a 0 D/1 D AgI/MoO_(3)Z-scheme photocatalyst with striking photocatalytic performance was constructed *** one-dimensional MoO_(3)nanobelts were prepared by a simple hydrothermal method,and then it was modified by AgI nanoparticles in a handy deposition *** choosing sulfamethoxazole(SMZ)as the target contaminant,the rate constant value of the optimal 0 D/1 D AgI/MoO_(3)composite could hit up to 0.13 min^(-1),which is nearly 22.4 times and 32.5 times as that of pure MoO_(3)(0.0058 min^(-1))and AgI(0.0040 min^(-1)),respectively.A series of detailed characterizations give evidences that the charge transfer in the composite followed Z scheme ***,efficient separation/transfer and the remained high redox activity of photogenerated carriers played a vital role in the sharply enhanced photocatalytic *** possible degradation pathways of SMZ were proposed based on the intermediates detected by high-performance liquid chromatography-mass spectrometry(HPLC-MS).Meanwhile,the magnificent cyclic stability makes the material a promising material in the practical application.
