| 摘 要： | 选用典型的非活性载体MgO、γ-Al2O3和活性载体TiO2、CeO2,采用硼氢化钠直接还原法制备4种负载型纳米金催化剂,催化甲醛氧化。结果表明,其对甲醛氧化的活性规律为Au/CeO2>Au/TiO2>Au/γ-Al2O3>Au/MgO,并对其进行了金含量、比表面测定和TEM形貌分析,为净化甲醛污染提供了有效依据。

| Abstract: | Typical nonactive supports MgO,γ-Al2O3 and active supports TiO2,CeO2 were choosed to prepare the supported gold catalysts.NaBH4 was used as reductant,formaldehyde was treated by catalytic oxidation.The results indicated the activity regularity for formaldehyde oxidation was Au/CeO2>Au/TiO2>Au/γ-Al2O3>Au/MgO.Specific surface area(SBET) and transmission electron microscopy(TEM) were used to characterize the catalysts.It gave an effective basis for the purification of formaldehyde pollution. |
