請問能否直接在管式爐里加熱三聚氰胺的弱酸性溶液得到g-C3N4? 從這篇文章里看到的Effect of morphology on the photocatalytic activity of g-C3N4 photocatalysts under visible-light irradiation 原文:First, 5 g of melamine (purchased from A.R., Sinopharm Chemical Reagent Co., Ltd.) powder was dissolved in 150 ml of hot water. Then, a drop (about 1 ml) of concentrated hydrochloric acid (37.5%, bought from Sinopharm Chemical Reagent Co.,Ltd.) was introduced into the solution under magnetic stirring. Subsequently, the solution was transferred into two porcelain crucibles placed at a high temperature and a medium temperature site with a tube furnace. In consequence, the temperature of tube furnace was raised to and maintained at 550 1C for 2 h under Ar protection. After the temperature fell into the room temperature, the deposited yellow powders in the two crucibles and on the quartz pipe orifice (low temperature range) were collected. The as-prepared three samples were washed with deionized water before drying at 60 1C for 24 h. 翻譯:首先,將5g三聚氰胺(購自A.R.,Sinopharm Chemical Reagent Co.,Ltd。)粉末溶于150ml熱水中。 然后,在磁力攪拌下將一滴(約1ml)濃鹽酸(37.5%,購自Sinopharm Chemical Reagent Co.,Ltd。)引入該溶液中。 隨后,用管式爐將溶液轉(zhuǎn)移到放置在高溫和中溫位置的兩個瓷坩堝中。 結(jié)果,在Ar保護下,管式爐的溫度升高并保持在550℃并保持2小時。 在溫度降至室溫后,收集兩個坩堝中和石英管孔(低溫范圍)上沉積的黃色粉末。 將所制備的三個樣品用去離子水洗滌,然后在60℃下干燥24小時。 但是另外我都搜遍了也沒有用這種方法的,請問有沒有人試過? |
