| 摘 要： | 采用高能球磨法, 以氮化锂和酰氯氰脲作为前驱物, 并在反应物中滴入少量丙酮制备石墨相氮化碳. 将获得物在真空条件下的管式炉中热处理, 制备出球形体材料. XRD结果表明, 合成的样品为结晶的石墨相氮化碳. FTIR和XPS给出合成的石墨相氮化碳内部氮原子和碳原子的主要键合状态. 通过透射电子显微镜分析可知, 合成样品主要由直径为200~300 nm的球形粒子组成.

| Abstract: | The mechanochemical reaction between C3N3Cl3 and Li3N with acetone as the additive medium was carried out via high\|energy ball milling. Carbon nitride was obtained by baking the acquisition in a tube furnace in vacuo. XRD reveals the transformation of crystalline structure and it also shows that the product was transformed to graphitic carbon nitride after being milled for 80 hours at 200 r/min and baked at 573 K for 2 h. FTIR spectrum implies the existence of C-N and C=N bonds. XPS analysis also reveals the existence of sp2 CN bonds in the final product. TEM investigation shows that the product mainly consisted of particles with their diameters ranging from 200 to 300 nm. |
