中文摘要 | 本文研究一氧化碳在氧化銅/γ-氧化鋁和鉑-氧化銅/γ-氧化鋁觸媒上的氧化反應。結果顯示這些觸媒的行為會隨銅含量的不同而改變。最佳的銅含量約為6 wt%銅金屬。在氧化銅/γ-氧化鋁觸上,燒結會對較低含銅量者有益而對較高含銅量者有害。在硫毒害下,在鉑-氧化銅觸媒上的銅表面的活性要比在氧化銅上者來得高。 |
英文摘要 | C uO/γ-Al₂O₃ and Pt-CuO/γ-Al₂O₃ catalysts for CO Oxidation were studied. It was shown that these catalysts may exhibit different behavior with different copper content. An optimum copper content of about 6 wt% Cu metal was observed. On CuO/γ-Al₂O₃ catalysts, sintering may have a beneficial effect with lower copper content but a detrimental effect with higher copper content. Under sulfur polsoning, the activity of the copper surface is higher in the Pt-CuO catalysts than in the CuO catalysts. |
