  6. The temperature from amorphous to crystal of tungsten oxide sol - gel films with catalyst is increased and the reason is in studying. as results of tunnel scan - afm, both pt sputtered tungsten oxide films and pt sputtered tungsten oxide sol - gel films there is distinct and out - of - order parallel line structure on the surface of amorphous. molecules of the sample tend to tetrahedron and the former has more planarer structure

    隧道-原子力顯微鏡測試結果表明:非晶態時，磁控濺射摻鉑薄膜樣品表面和溶膠凝膠摻鉑樣品表面都有明顯的平行線狀結構，長程無序，分子趨於四面體結構，只是前者比後者表面較平整;晶態時，磁控摻鉑樣品在自然生長面上原子呈平面分佈，長程有序，溶膠摻鉑樣品則呈wo6面心結構。
  7. Synthesis and activity of hydrofining catalyst - tungsten phosphie

    加氫精製磷化鎢催化劑的合成與活性
  8. Preparation of tungsten phosphide catalyst and its hydrodesulfurization performance

    磷化鎢催化劑的制備及加氫脫硫性能
  9. Study on hydro - denitrogenation and activation of novel phosphide tungsten catalyst

    新型磷化鎢催化劑加氫脫氮及活化性能研究
  10. Preparation condition and hydrogenation capacity on the novel tungsten phosphide catalyst

    新型磷化鎢催化劑合成條件及加氫性能考察
  11. Because the tungsten from the phosphotungstic acid could pull out and deposit on the surface of catalyst, and the electronegativity of mo - o is smaller than that of w - o. the smaller the electronegativity is, the higher oxidation activity is. thus phosphomolybdic acid shows better catalytic oxidation activity than phosphotungstic acid

    由於磷鎢酸中的鎢可以脫出並少量沉積到催化劑表面，而且從電負性來說mo - o的鍵能小於w - o ，鍵能小的雜多酸有較強的氧化性，所以鉬系雜多酸催化活性要好於鎢系雜多酸。
  12. The tungsten oxide films with catalyst by two methods were characterized by x - diffractometer, tunnel scan - atomic force microscope, ft - ir, double - beam uv - vis - nir spectrophotometer and speediness volt - ampere cycle meter. as results of x - diffractometer, pt / wo3 sputtered film samples are crystal when annealed at 400 with distinct diffractive acuti - apices

    本文分別用x衍射儀、隧道-原子力顯微鏡、傅立葉變換紅外光譜儀、雙束紫外可見分光光度計、快速伏安循環法等表徵了用以上兩種方法制備的三氧化鎢摻雜薄膜。
  13. Atoms of the film by dc reactive magnetron with pt sputtered tend to plane ordinal structure. molecules of the the film by sol - gel with pt sputtered tend to be surface center structure as wo6. as results of ft - ir, the characteristic oscillation of the tungsten oxide sol - gel film with pdcl2 catalyst is more distinct with the higher temperature at the wave band

    這兩種方法結合制備的三氧化鎢摻雜薄膜中溶膠摻鉑樣品綜合了溶膠凝膠法與直流磁控濺射法的優點，其薄膜疏鬆多孔，充分快速響應了鉑催化劑離化的氫，具有良好的氫敏性能，是制備氫氣傳感器薄膜的首選方法。
  14. For the existence of w2c, tungsten carbide catalyst is not resistant to corrosion very well

    由於w2c的存在導致催化劑的抗腐蝕性能不好，而mo _ 2c催化劑抗腐蝕性能相對較好。
