For the preparation of CeO2 nanoparticles, cerium nitrate and azodicarbonamide were used as starting materials and other materials were used as additives. Typically, 0.434 g Ce(NO3)3 ¢ 9H2Owas dissolved in 50mLdoubly distilledwater, and 0.11 g AZOwas added to the aqueous solution of Ce(NO3)3. This is followed by the addition of a different amount of additives.The solution was sonicated at room temperature for 3 h by a high-intensity ultrasonic probe (Misonix, XL sonifier, 1.13-cm-diameter Ti horn, 20 KHz, 100 W/cm2). During sonication,the temperature of the reaction mixture rose to ca. 80±C. The suspension was then centrifuged, and the precipitate was washed with distilled water and ethanol and then dried under vacuum at room temperature. A yellow fine powder was obtained. The pH of the solution is measured before and after the sonication and is found to increase after the reaction. |

我們以硝酸鈰和偶氮二甲酰胺為原料,其他物質(zhì)為添加劑來(lái)制備納米CeO2,。通常,將0.434gCe(NO3)3 ¢9H2O(分子式不太理解)溶解在50ml的二次蒸餾水中形成溶液,再向該溶液中加入0.11g的偶氮,接著加入不同量的添加劑。在室溫下將該溶液用高強(qiáng)度的超聲波探頭(Misonix, XL 聲波降解器,直徑1.13cmTi探頭, 超聲頻率20 KHz, 功率100 W/cm2)聲處理3h。聲處理期間,反應(yīng)混合物的溫度升至約80℃。將懸浮物離心處理,得到的沉淀物用蒸餾水和乙醇洗滌之后,再在室溫下進(jìn)行真空干燥。最終得到黃色細(xì)粉末。聲波降解前后對(duì)溶液的pH值測(cè)量發(fā)現(xiàn)反應(yīng)后pH值較之有所上升。 希望對(duì)樓主有所幫助! |

| 為了制備納米氧化鈰,我們以硝酸鈰和偶氮甲酰胺作為起始原料,其他的物質(zhì)作為添加劑。通常,將0.434g的Ce(NO3)3•9H2O(該物質(zhì)名稱的翻譯需要確認(rèn)下給的英文原文)溶解在50ml的雙蒸餾水中形成溶液,再向該溶液中加入0.11g的偶氮,接著加入不同量的各種添加劑。該溶液在室溫下由一個(gè)高強(qiáng)度的超聲探頭(Misonix, XL sonifier, 1.13cm直徑的Ti探頭, 超聲頻率20 KHz, 功率100 W/cm2)進(jìn)行超聲輻射3h。在超聲輻射的過(guò)程中,反應(yīng)混合物的溫度升到了約80攝氏度左右。然后將得到的懸浮物通過(guò)離心分離,將得到的沉淀物分別經(jīng)過(guò)蒸餾水洗滌和乙醇洗滌,再在室溫下進(jìn)行真空干燥。最終得到一種黃色的細(xì)粉。在超聲輻照前后分別對(duì)溶液的pH值進(jìn)行了測(cè)量,發(fā)現(xiàn)超聲后pH值有所上升。 |
