摘　　要：以CTAB作模板剂合成正交相和六方相的MoO3微米棒,分别用XRD、SEM、TEM、FT-IR等手段对产物进行表征.结果表明:合成的产物在有无太阳光照射的条件下都能够使含氮染料脱色.比较了两个相的MoO3对含氮染料的催化脱色性能,发现α-MoO3的脱色率高于h-MoO3,这可能归因于α-MoO3具有高的结晶性.此外,还观察到MoO3样品对染料刚果红的变色性,且太阳光的照射对此过程没有影响.Self-assembly orthorhombic and hexagonal MoO3 microrods were successfully synthesized using CTAB as the template.The as-synthesized products were characterized by XRD,SEM,TEM and FT-IR.The results showed that the products could make azo dyes decolor with or without sunlight irradiation.The catalytic behaviors of the as-synthesized MoO3 microrods were observed： α-MoO3 exhibited much better efficiency than that of h-MoO3,which might be attributed to the higher crystalline of α-MoO3 and the differences of crystal structure between the two phases MoO3.Furthermore,it was found that both phases of MoO3 could change the color of Congo red dye and sunlight irradiation had little effect on this process.
