中文摘要:氮化碳(g-C3N4)是一种新型二维碳纳米材料,目前已在催化降解、生物传感、能源存储和生物医药等领域得到了广泛应用。g-C3N4材料结构中丰富的含氮官能团和电子离域特性,赋予其独特的理化性质,使之能够与一些离子或分子产生络合、疏水、π-π键、氢键和静电力等相互作用。此外,g-C3N4材料比表面积大、性质稳定且制备简单,价格低廉,在样品前处理领域展现出良好的应用潜力。近几年,基于g-C3N4材料的样品前处理新方法不断涌现,该文总结了g-C3N4及其复合材料在固相萃取、磁性固相萃取和固相微萃取等领域的应用并进行了展望。

Applications of Graphitic Carbon Nitride and Its Composites in Sample Pretreatment
Abstract:Graphitic carbon nitride(g-C3N4),a novel two dimensional carbon based nanomaterial,has been widely applied in catalysis degradation,biosensor,energy storage and biomedicine.The in built N rich functional groups and electronic delocalization properties endow g-C3N4 with complex adsorption capabilities,including complexion,hydrophobic effect,π-π conjugation,hydrogen bond and electrostatic interaction.Particularly,the large specific surface area,satisfactory pH tolerance,facile and inexpensive preparation of g-C3N4 make itself qualified as an extraordinarily wonderful adsorbent.In recent years,g-C3N4 and its composites have been applied to the sample pretreatment in solid phase extraction,magnetic solid phase extraction and solid phase microextraction.In this review,the applications of g-C3N4 materials in sample pretreatment are summarized,and the future trends and prospects of g-C3N4 and its composites in sample pretreatment are also presented.
