| 摘 要： | 采用沉积-沉淀法(deposition precipitation,简称DP法)和共沉淀法(coprecipitation,简称 CP法)制备了负载型纳米金催化荆Au/Fe2O3,催化剂中金含量(质量分数)小于1%.并以甲醛完全氧化反应作为研究的目标反应.这个反应可以有效地去除室内空气中的有害成分甲醛.通过催化活性的测试和XRD、TEM、TPR等技术对催化剂进行了表征.结果表明,两种方法制备的催化剂有各自的优势和特点,其中DP法制备的催化剂金含量(质量分数)只有0.67%的情况下,经过条件优化,甲醛完全转化温度为80℃,是一个较好的结果;而CP法制备的样品有较好的抗热性,可能有利于催化剂的使用寿命.因此,本工作为该类催化剂实用化提供了有价值的信息和依据. |

| Abstract: | Owing to the use of decorative materials containing formaldehyde in homes,the content of formaldehyde in indoor air frequently exceeds the National Standards.Accordingly,people's health may be affected.In this work,supported nanogold catalysts Au/Fe2O3 were prepared by deposition precipitation(DP)and coprecipitation(CP)methods.The gold content in the catalysts is less than 1 wt%.The complete oxidation of formaldehyde(HCHO)was used as a test reaction,to check if this could be an effective approach to remove ... |
| Keywords: | gold nanocatalysts full oxidation of formaldehyde cleaning of the indoor air catalyst preparation method |
