【摘要】 <正>以MnOOH纳米棒作为前驱体,氯金酸为原料,利用3-氨丙基三乙氧基硅烷为连接剂,成功制备了MnOOH/Au纳米复合材料。分别利用X射线粉末衍射(XRD)、扫描电子显微镜(SEM)、X射线能谱(EDS)对产物进行了表征。SEM图片显示Au纳米粒子均匀负载在MnOOH纳米棒表面,粒子尺寸约为50nm。通过紫外吸收光谱研究产物的催化性能,结果表明该MnOOH/Ag纳米复合材料对催化4-硝基苯酚(4-NP)的还原更多还原

【Abstract】 MnOOH/Au nanocomposite materials have been successfully synthesized via MnOOH nanorods as precursor, employing HauCl4 as the reactants and(3-aminopropyl) triethoxysilane as coupling reagent. The product was characterized by X-ray powder diffraction(XRD), scanning electron microscopy(SEM), and energy dispersive X-ray spectrometry(EDS). SEM observations showed that the Au nanoparticles were loaded on the surface of MnOOH nanorods evenly, and with average size of 50 nm. Ultraviolet spectrum analysis indicated that the MnOOH/Au nanocomposites had a very good catalytic effect on the reduction reaction of 4-nitrophenol.更多还原
