“…designed and synthesized porous PCN nanosheets by treating the MA with citric acid and then thermal condensing under an N 2 atmosphere. [ 327 ] The obtained PCN nanosheets improved significantly in HCHO decomposition with LED light, which is contributed to the reduced diffusion distance of charges, improved reactive sites for HCHO ( Figure 13 A ). This work opens the avenue for PCN in the application of VOC degradation under solar irradiation.…”

The techniques for the production of the environment have received attention because of the increasing air pollution, which results in a negative impact on the living environment of mankind. Over the decades, burgeoning interest in polymeric carbon nitride (PCN) based photocatalysts for heterogeneous catalysis of air pollutants has been witnessed, which is improved by harvesting visible light, layered/defective structures, functional groups, suitable/adjustable band positions, and existing Lewis basic sites. PCN-based photocatalytic air purification can reduce the negative impacts of the emission of air pollutants and convert the undesirable and harmful materials into value-added or nontoxic, or low-toxic chemicals. However, based on previous reports, the systematic summary and analysis of PCN-based photocatalysts in the catalytic elimination of air pollutants have not been reported. The research progress of functional PCN-based composite materials as photocatalysts for the removal of air pollutants is reviewed here. The working mechanisms of each enhancement modification are elucidated and discussed on structures (nanostructure, molecular structue, and composite) regarding their effects on light-absorption/utilization, reactant adsorption, intermediate/product desorption, charge kinetics, and reactive oxygen species production. Perspectives related to further challenges and directions as well as design strategies of PCN-based photocatalysts in the heterogeneous catalysis of air pollutants are also provided.

“…[1][2][3][4] It is extensively regarded as a known human carcinogen. [5][6][7][8][9] Because more than 80% of the people spend their time in an indoor environment, removing indoor HCHO is of great importance to human health. Many approaches including adsorption, [10][11][12][13] photocatalysis, [14][15][16] plasma oxidation, [17][18][19] and thermal catalysis oxidation [20][21][22][23][24][25] have been adopted to eliminate indoor HCHO.…”
