A Solvent‐Polarity‐Induced Interface Self‐Assembly Strategy towards Mesoporous Triazine‐Based Carbon Materials

Abstract

Triazine-based materials with porous structure have recently received numerous attentions as af ascinating new class because of their superior potential for various applications.H owever,i ti ss till af ormidable challenge to obtain triazine-based materials with precise adjustable meso-scaled pore sizes and controllable pore structures by reported synthesis approaches.H erein, we develop as olvent polarity induced interface self-assembly strategy to construct mesoporous triazine-based carbon materials.I nt his method, we employamixed solvent system within as uitable range of polarity (0.223 Lippert-Mataga parameter (Df) 0.295) to induce valid self-assembly of skeleton precursor and surfactant. The as-prepared mesoporous triazine-based carbon materials possess uniform tunable pore sizes (8.2-14.0 nm), high surface areas and ultrahigh nitrogen content (up to 18 %). Owing to these intriguing advantages,t he fabricated mesoporous triazine-based carbon materials as functionalizedporous solid absorbents exhibit predominant CO 2 adsorption performance and exceptional selectivity for the capture of CO 2 over N 2 .

Carbazole-Based Porous Organic Polymers with Ag(I) Doping and Derived Porous Carbon for Enhanced Adsorption of Polycyclic Aromatic Hydrocarbons

“…These advantages are beneficial for the large scale up and adsorption of PAHs. Also, the rigid aromatic skeletons make POPs desired precursors to prepare porous carbon materials that possess abundant porosity and higher S BET by direct pyrolysis. , The porous carbon materials also have been widely used in adsorption, catalysis, and energy storage because of the high conjugated system and designable porous structures . Especially, the introduction of heteroatoms (e.g., N, O, S) that possessed lone pair electrons into porous carbon materials can increase active sites and improve the adsorption capacity by the more abundant p−π conjugation interaction. , Furthermore, for the adsorption of PAHs, coordinating metal ions to introduce cation−π force between ions and PAHs is helpful to improve the adsorption capacity.…”

Synthesis of Different Nano‐layer Shells (Mono‐, Bi‐, and Alloy Layers)‐Coated Gold Spherical Nanoparticles Core for Catalysis

“…Catalysis is an important for the growth of a sustainable world and it helps to elimination of atmospheric pollution. Qiao and co‐workers extensively studied the catalytic activity of various porous materials [28–30] . In catalysis, reduction of nitroaromatics is an important because nitroaromatics are environmental pollutants, carcinogenic and the reduced products of aromatic amines are found in various applications including medicines and dyes.…”

“…Qiao and co-workers extensively studied the catalytic activity of various porous materials. [28][29][30] In catalysis, reduction of nitroaromatics is an important because nitroaromatics are environmental pollutants, carcinogenic and the reduced products of aromatic amines are found in various applications including medicines and dyes. Hence, the synthesis of important aromatic amines from hazardous nitroaromatics is an important task for both to minimize the pollutant and enhancing the economy.…”
