| 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. |
