应该是沉积-沉淀法!或者沉积-浸渍法...

沉积—沉淀法(Deposition-precipitation,简称DP法)是将金属氧化物载体加入到HAuCl4的水溶液中形成悬浮液,在充分搅拌的条件下,控制一定的温度和pH值,使之沉积在载体表面上,随后进行过滤、洗涤、干燥、焙烧等处理,得到负载金催化剂。对于制备高活性的纳米金催化剂,该方法是广泛使用并且比较有效的方法之一。
似乎也不是沉积沉淀法吧!

很少有人这么称呼,把你的步骤列出来看看如何定义!
有“沉淀沉积”法:precipitation,An aqueous solution containing 0.01 g/mL H2PtCl6 was added dropwise to a stirred suspension of 2.0 g support (HNO3-MWNTs, H2O2-MWNTs and S-MWNTs). The slurry was stirred for 30 min at room temperature and sonicated for 2 h, reduced by an aqueous solution of KBH4. And then the catalyst was filtered and washed with distilled deionized water to remove residual chlorine. The loading amount of Pt was controlled and confirmed by ICP as 5.0 wt.% of the support.
文献:Applied Catalysis B: Environmental, Volume 106, Issues 3–4, 11 August 2011, Pages 423-432

有“直接浸渍”法:Ni catalysts sized from 4.5 to 45.0 nm were prepared via direct impregnation of [Ni(en)3]2+ (en, ethylenediamine), [Ni(EDTA)]2− (EDTA; ethylenediaminetetraacetic acid), nickel(II) acetylacetonate dihydrate (99+%), nickel(II) acetate, and Ni(NO3)2⋅6H2O onto a spherical SiO2 support。

有“共沉淀”法:A series of Cu0.4Zn5.6−xMgxAl2(OH)16CO3 LDHs were prepared by co-precipitation. Cu(NO3)2·3H2O (0.01 mol), Al(NO3)3·9H2O (0.05 mol), Zn(NO3)2·6H2O, and Mg(NO3)2·6H2O (AR, Sinopharm Chemical Reagent Co. Ltd., China) were dissolved together in 400 mL deionized water. The total amount of Zn(NO3)2·6H2O and Mg(NO3)2·6H2O was controlled to 0.14 mol, and this mixed solution is referred to as A. Solution B was a mixture of Na2CO3 and NaOH (AR, Sinopharm Chemical Reagent Co. Ltd., China) with concentrations of 0.25 and 0.8 mol/L, respectively. Solutions A and B were simultaneously added into a glass reactor under vigorous stirring at room temperature and of a pH value of 9.5. The slurry was transferred into a custom-designed stainless autoclave (1000 mL) equipped with a Teflon inner layer, put into an oil bath, and aged at 120 °C for 20 h under stirring, filtered off, and washed thoroughly with distilled water. The precipitate was then dried overnight at 80 °C and identified as Cu0.4Zn5.6−xMgxAl2(OH)16CO3, in which x refers to the amount of Mg (0 < x < 5.6).

汉文的有许多叫共沉淀-浸渍法!主要就是用酸或碱把浸渍液中和,生产沉淀,搅拌均匀,滴加到载体上浸渍。不知道这是不是应该叫沉淀浸渍法!
