摘要/Abstract

摘要：

许多微生物对金属离子有较强的吸附还原能力. 本文利用大肠杆菌(DH5α)对金属离子较强的吸附与还原能力制备了Au@DH5α, 再利用大肠杆菌的水分来水解钛酸四丁酯, 得到Au@DH5α-Ti(OH)₄样品, 焙烧去除大肠杆菌后得到氧化钛包裹的纳米金粒子催化剂Au@TiO₂. 以N₂吸附, X 射线衍射(XRD), 紫外-可见漫反射光谱(UV-Vis DRS), 热重-差热分析(TG-DTA), 透射电镜(TEM)对所得材料进行表征. 结果表明:该催化剂具有与大肠杆菌类似的杆状结构, 以大肠杆菌为生物模板生成的氧化钛孔道结构在一定程度上抑制了金粒子的聚集长大.随菌体用量的增加, 金粒子减小,等离子共振吸收发生紫移, 催化剂有较大的比表面积, 但催化剂中积炭量也会增加. 将该催化剂用于CO 氧化反应, 发现当菌体用量为100 或150 mL 时, 制得的金催化剂可在80 ℃下将CO完全氧化为CO₂.

Abstract:

Many microorganisms can adsorb metal ions strongly and even reduce them to their metal states. We studied the adsorption of gold nanoparticles on Escherichia coil (DH5α) to form Au@DH5α. Titanium tetrabutoxide was added to Au@DH5αto prepare Au@DH5α-Ti(OH)₄ by hydrolysis. The DH5αtemplate was removed by calcination in air to obtain the Au@TiO₂ catalyst. These materials were characterized by N₂ adsorption, X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS), thermogravimetry-differential thermal analysis (TG-DTA), and transmission electron microscopy (TEM). The results show that the gold catalyst maintains a rod-like structure similar to DH5αand the porous structure of the titanium oxide prepared using DH5αas a biological template can prevent the aggregation of gold nanoparticles to some extent. With higher amounts of DH5αdosage, smaller gold nanoparticles were obtained and the surface plasmon absorption of gold nanoparticles shifted toward shorter wavelengths. The obtained gold catalyst has a larger surface area than the catalyst prepared by the impregnation method. However, this increases the coke content of the catalyst. Catalytic activity was evaluated by the CO oxidation reaction. We found that with a DH5αdosage of 100 or 150 mL, the obtained gold catalyst can convert CO to CO₂ completely at 80 ℃.
