| 摘 要： | 探索了以活性炭为载体制备负载型金催化剂的可行性。大量实验表明,将金直接负载在活性炭上,不能够得到具有很好催化活性的催化剂。而以MOx/C作为复合载体能够制备得到具有较高催化活性的金催化剂。进一步探讨了焙烧条件,以及不同载体材料对金催化剂活性的影响。

| Abstract: | The feasibility of preparation of gold catalyst supported on active carbon with good performance on carbon monoxide oxidation was investigated. No high active gold catalyst on active carbon was gained though several preparations were employed. However, gold catalysts on composite supports of MOx/C exhibited higher activity than Au/C catalyst. The influences of pretreatment conditions and nature of supports on CO catalytic oxidation over gold catalyst were further studied. |
