Aligned polypyrrole (PPy) micro/nanotubules were synthesized via a self-assembly method using FeCl3 as oxidant and Acid Red 1 (C.I. 18050, 5-(acetylamino)-4-hydroxy-3-(phenylazo)-2,7-naphthalenedisulfonic acid) as dopant. PPy has a typical length of 530 mm and a unique rectangular-sectioned morphology. Its general morphology could be manipulated by varying synthetic conditions including polymerization time, monomer concentration, oxidant species, and stirring. The synthesized PPy and reaction intermediates were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD), and solubility tests in methanol and water. Our observation and results suggest a plausible formation mechanism of rectangular-sectioned PPy micro/nanotubules. AR1eFe(II) complex formed from the complexation of Acid Red 1 and Fe2þ(reduced from Fe3þ), which precipitated in the aqueous solution, might have functioned as"template"during the polymerization of pyrrole monomers. The conductivity of PPy with different morphologies was also measured and compared.

以四氯化钛（TiCl4） 为原料，用溶胶凝胶法制备了纳米氮杂二氧化钛光催化剂（TiO2Ox Nx），并利用化学还原法在纳米TiO2Ox Nx的表面负载了铂单质（Pt/TiO2Ox-Nx），X射线衍射（XRD） 结果表明，Pt/ TiO2Ox Nx光催化剂为锐钛矿型结构，由紫外-可见漫反射光谱显示催化剂的能隙与纯TiO2不同，而与TiO2Ox-Nx 相一致。产氢实验结果表明，Pt的负载可以明显提高光催化剂的产氢活性，并且催化剂的产氢活性与Pt的质量分数之间呈现双峰现象，当Pt的质量分数为0.05%和0.35%时，产氢活性分别达到极大值。研究结果表明，当Pt的质量分数为0.05%时，表面Pt粒子的大小约为10nm且分布均匀，显示该尺度的Pt粒子对于催化剂的产氢活性有较大的促进作用。

Non-woven poly (lactic-co-glycolic acid) (PLGA) nanofibers were prepared by electrospinning technology. The morphology of the electros pun fibers was observed using scanning electron Microscopy (SEM) and the fiber diameter was calculated. Primary human dermal fibroblasts (HDFs) were cultured to evaluate the biocompatibility of the electrospun PLGA nanofibers. The results of MTT testing and SEM showed that the PLGA nanofibers have the morphology of interwoven and highly porous structure and can support the attachment and proliferation of HDFs. It is can be expected to be a potential scaffold material for tissue engineering.

以钛酸四丁酯和重铬酸铵为原料，采用溶胶凝胶法制备Cr2O3-TiO2复合型光催化剂!并利用浸渍法在Cr2O3-TiO2表面分别负载Fe、Mn、Mo过渡金属，制备了Fe-Cr2O3-TiO2、Mn-CrO3-TiO2、Mo-CrO3-TiO2三元复合型光催化剂。通过X射线衍射（XRD）、比表面分析（BET）和紫外可见吸收光谱（Uv-Vis）对催化剂进行了表征。XRD结果表明：TiO2为金红石结构；Cr2O3为绿铬矿结构。催化剂在紫外光和可见光条件下均具有光催化分解水产氢活性，紫外光条件下三元复合型光催化剂可以明显提高光催化产氢活性，其中Mo-CrO3-TiO2活性最高，而在可见光条件下，三元复合型光催化剂产氢活性略低于Cr2O3-TiO2。

合成了Ni掺杂中孔TiO2光催化剂，其吸收光谱阈值红移至500mg，500℃焙烧后依然保持中孔结构。喇曼光谱证实，这种催化剂具有锐钛矿晶型。在Na.5/Na.SO。复合牺牲剂体系下，对Ni掺杂中孔TiO2和Ni掺杂颗粒TiO2两种催化剂的产氢活性进行了考察，发现前者比后者提高了近1倍。
