g-C3N4催化剂的制备方法？请问能否直接在管式炉里加热 三聚氰胺 的弱酸性溶液得到g-C3N4？ 从这篇文章里看到的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. 翻译：首先，将5g三聚氰胺（购自A.R.，Sinopharm Chemical Reagent Co.，Ltd。）粉末溶于150ml热水中。 然后，在磁力搅拌下将一滴（约1ml）浓盐酸（37.5％，购自Sinopharm Chemical Reagent Co.，Ltd。）引入该溶液中。 随后，用管式炉将溶液转移到放置在高温和中温位置的两个瓷坩埚中。 结果，在Ar保护下，管式炉的温度升高并保持在550℃并保持2小时。 在温度降至室温后，收集两个坩埚中和石英管孔（低温范围）上沉积的 黄色粉末 。 将所制备的三个样品用 去离子水 洗涤，然后在60℃下干燥24小时。 但是另外我都搜遍了也没有用这种方法的，请问有没有人试过？查看更多1个回答 . 4人已关注
