中文摘要:石墨相氮化碳是一种新兴的二维蜂窝状纳米材料,其结构中C原子和N原子以sp2方式杂化,通过PZ轨道上的孤对电子相互作用形成类似于苯环的π键,构成高度离域的共轭体系。这一独特结构使其可与一些离子或分子产生疏水、π-π键、氢键和静电力等相互作用,进而成为一种颇具潜力的吸附剂。但同时石墨相氮化碳本身紧密堆叠的层状结构导致其比表面积较小(< 10 m2/g)。介孔氮化碳应运而生,其具有孔尺寸为2~50 nm的典型介孔结构,与石墨相氮化碳相比,比表面积和孔体积获得有效提高且吸附位点更加丰富。该文总结了介孔氮化碳的合成方法及其在环境卫生领域的应用,并展望了其发展方向。

Synthesis of a Mesoporous Graphitic Carbon Nitride and Its Application in the Field of Environmental Sanitation
Abstract:Graphitic carbon nitride,an emerging two-dimensional honeycomb nanomaterial,is composed of π-conjugated graphitic planes via sp2-hybridized of C and N through the interaction of lone pair electrons on the PZ orbital. This highly delocalized conjugated structure endows it multiple interactions with target molecules or ions,such as hydrogen bonds,π-π interaction,hydrophobic effects,and electrostatic interactions. Thus,graphitic carbon nitride is regarded as a potential adsorbent. However,the aggregated layer-by-layer structure resulted in its limited surface area(< 10 m2/g). Compared with bulk sample,mesoporous graphitic carbon nitride with typical pore size ranging from 2-50 nm possesses larger surface area and higher pore volume,which could provide more active sites exposed on its surface. The synthesis of mesoporous graphitic carbon nitride and its application in the field of environmental sanitation are herein summarized,and its development trend is also prospected.
