摘要:
采用了简单的软模板水热合成法,制备了十二面体形状的有序介孔聚合物(OMP),在高温碳化下转化为有序介孔碳(OMC)。之后将有序介孔碳用氨气活化,制备得到有序介孔氮掺杂碳(OMNC)。通过TEM,SEM,BET,XPS,XRD,拉曼光谱仪等方法对制备的产品进行表征分析,探究氮掺杂过程对材料结构和性能影响。将不同活化温度下制备的OMNC负载钨酸铋,在可见光的照射下对一定浓度的罗丹明B溶液进行光降解反应,探究在不同温度活化的OMNC负载相同量的钨酸铋的光催化效果,结合光催化反应的活性和效果揭示OMNC活化温度-孔道结构-光催化性能之间的构效关系。
Abstract:
In this research, a novel soft templating method was employed to synthesize ordered mesoporous polymer(OMP)under hydrothermal process. It was then converted to ordered mesoporous carbon(OMC)under high temperature carbonization. The ordered mesoporous carbon was then activated with ammonia gas to prepare ordered mesoporous nitrogen-doped carbon(OMNC). Such obtained products were characterized by TEM, SEM, BET, XPS, XRD, Raman spectroscopy, etc. The effects of nitrogen doping on the properties of the materials were investigated. After loading bismuth tungstate with OMNC which were activated under different temperature, a certain concentration of Rhodamine B solution was subjected to explore the photo-catalytic behaviour of OMNC under visible light irradiation. According to these results, the structure-activities relationship among activated temperature, porous structure and photo-catalytic effects were investigated in detail.
