介孔石墨相氮化碳吸附材料在环境中的应用

Applications of Mesoporous Graphitic Carbon Nitride Adsorption Materials in Environment

石墨相氮化碳(Graphitic carbon nitride,g-C_3N_4)是一种由碳(C)和氮(N)元素组成的共轭聚合物材料,具有平面的三嗪聚合物(Poly(tri-s-triazine))网络结构。比起大部分其他碳材料,氮化碳是富电子体,因而赋予了其特殊的性质。然而目前对于g-C_3N_4的研究主要集中在其相关催化作用(光催化,电催化和光电催化),对于g-C_3N_4的吸附作用的研究相对很少涉及。本文探讨了g-C_3N_4材料在吸附领域中的应用,简要综述了G-C_3N_4的性质、制备方法及其作为吸附材料的应用现状,最后展望了石墨型氮化碳在吸附应用领域的未来发展方向。

Graphitic carbon nitride（g-C3N4）is a conjugated polymer material composed of carbon（C）and nitrogen（N）elements with a planar tri-s-triazine network structure.Compared to most other carbon materials,carbon nitride is an electron rich body,which endows its various special and interesting properties.The current research on g-C3N4 mainly focuses on its related catalytic ability（photo-catalysis,electrocatalysis and photo-electrocatalysis）,however,studies on the adsorption application of g-C3N4 is relatively few.The purpose of this paper is to review the application of g-C3N4 in the field of adsorption.In this paper,the properties and preparation methods of g-C3N4 and their applications as adsorbents are briefly introduced.Finally,the future research direction of graphite carbon nitride in adsorption applications is anticipated.
