After surface modification, Pt and Pd can be supported on the surface of CNTs. These novel catalysts were successfully used in the selective hydrogenation of cinnamaldehyde and halogenated aromatic nitro compounds.

经过表面修饰后，可以在纳米碳管表面均匀负载上Pt和Pd；分别把它们应用于肉桂醛和卤代硝基化合物的选择性加氢，取得较好的结果。

Infrared spectroscopic analysis shows that the water glass is chemically adsorbed on the surface of titanaugite but this reaction is weaker between the water glass and ilmenite; hetero-coagulation will occur easily under weak acidic condition because of the opposite surface charge of ilmenite and titanaugite.

红外光谱分析表明：水玻璃与钛辉石发生化学吸附，而在钛铁矿表面吸附较弱；在弱酸性条件下，由于钛铁矿与钛辉石表面带异相电荷而容易发生异相凝聚，添加水玻璃使二者表面电位均显负电性，矿粒间静电斥力迅速增大，从而减弱矿粒间的异相凝聚。

Surface modified magnesium hydroxide particles were synthesized by one-step process using magnesium sulfate,ammonia liquor and sodium laurate as raw materials in alcohol-water system ac- cording to the spectra of FTIR,it was inferred that sodium laurate was bound on the surface of Mg_2 particles and an organic coat- ing layer also formed.

0引官Mg2是一种无机添加型无毒阻燃剂，具有阻燃、消烟、阻滴、填充等多重性能，与川3相比，具有高的热稳定性，高效促基材成炭作用和强除酸能力等特性，但也存在颗粒表面亲水疏油、易团聚、难分散、吸湿性强等缺点，导致材料加工成本增加和综合性能降低川。

Metallographic microscope and SEM results show that the surface and structure of nano-diamond/Ni brush electroplated composite coating are more smooth and compact than that of Ni coating. And on the surface of brush electroplated composite coatings, which appear to be the typical cluster crystals in a cauliflower shape, nano-diamonds are wrapped by nickel crystal grains.

金相显微镜和扫描电镜分析结果表明，与普通镍镀层相比，nano-diamond/Ni复合刷镀层的表面更加平整、致密，组织更加细化：nano-diamond/Ni复合刷镀层表面呈典型的&菜花头&形状，弥散分布的纳米金刚石被镍包裹。
