graphite catalyst 中文意思是什麼
graphite catalyst
解釋
石墨催化劑-
The catalyst for this reaction is iron chromium oxide with graphite as a binder.
進行這種反應的催化劑是以石墨為粘接劑的鐵鉻氧化物。 -
According to the results of the interface action, the metals are classified as following three kinds. one is the affine metals that can react with the diamond to form steady carbides, such as ti, w, cr, mo etc. other is the inert metals that have not any action with the diamond, such as cu etc. the third is catalyst metals that promote the transformation of the diamond into graphite when the metals come into contact with the diamond at high temperature, such as fe, co, ni etc
按照金屬與金剛石的界面作用結果，將典型金屬分為：與金剛石界面反應形成穩定碳化物的親和性金屬，如鈦、鎢、鉻、鉬等；與金剛石界面不反應的惰性金屬，如銅等；與金剛石界面接觸促使金剛石石墨化的石墨化金屬，如鐵、鈷、鎳等。 -
The main research findings were as follows : nickel had a higher catalysis than iron in the growth of cnts, and the thickness of catalyst affected the diameter of cnts. compared graphite and iron, when monocrystalline silicon was used as the substrate, cnts had a higher purity
通過sem和tem分析了不同條件下產物的形貌和結構，取得以下主要結果：在兩種單金屬催化劑中，鎳的催化活性高於鐵的催化活性，催化劑薄膜的厚度決定著生長納米碳管的直徑。
