Graphdiyne (GDY), a rising star of carbon allotropes, features a two-dimensional all-carbon network with the cohybridization of sp and sp 2 carbon atoms and represents a trend and research direction in the development of carbon materials. The sp/sp 2 -hybridized structure of GDY endows it with numerous advantages and advancements in controlled growth, assembly, and performance tuning, and many studies have shown that GDY has been a key material for innovation and development in the fields of catalysis, energy, photoelectric conversion, mode conversion and transformation of electronic devices, detectors, life sciences, etc. In the past ten years, the fundamental scientific issues related to GDY have been understood, showing differences from traditional carbon materials in controlled growth, chemical and physical properties and mechanisms, and attracting extensive attention from many scientists. GDY has gradually developed into one of the frontiers of chemistry and materials science, and has entered the rapid development period, producing large numbers of fundamental and applied research achievements in the fundamental and applied research of carbon materials. For the exploration of frontier scientific concepts and phenomena in carbon science research, there is great potential to promote progress in the fields of energy, catalysis, intelligent information, optoelectronics, and life sciences.

“…Taking P / P 0 = 0.5 as the dividing point, when P / P 0 < 0.5, the adsorption of gas in the coal depends on the van der Waals force, and the adsorption amount has a strong correlation with the surface roughness of the coal, so the fractal dimension D 1 can be used to reflect the pore surface roughness. When P / P 0 > 0.5, the gas adsorption is mainly controlled by multilayer adsorption and depends on the volume structure of the pores. − The more complex the pore volume structure is, the stronger the adsorption capacity is, so the fractal dimension D 2 can reflect the complexity of the pore volume structure. − The fractal dimensions D 1 and D 2 should be between 2 and 3. The closer D 1 and D 2 are to 3, the greater the pore surface roughness and pore volume structure complexity are.…”

There is a positive feedback mechanism of desorption, pulverization, and redesorption in the process of coal and gas outburst. The coal pore structure changes to some extent in the process of coal pulverization and has a related impact on the dynamic parameters of coal particle gas desorption. To understand the impact of desorption damage on the dynamic characteristics of coal particle gas desorption, in this paper, a self-developed coal particle gas desorption test device is used to measure the amount of methane desorption of different coal samples repeatedly desorbed under the same adsorption equilibrium pressure. The results show that the methane desorption kinetic curves of the four coal samples based on desorption damage basically have the same trend. Nie’s diffusion model can better describe the methane desorption characteristics of coal particles. After desorption, the methane desorption amount, initial desorption velocity, diffusion ability, and ultimate amount of methane desorption of the coal samples are greater than those before desorption. The desorption damage affects the relevant dynamic parameters of the coal particle gas diffusion model, and its impact on the outburst coal is greater than that on raw coal. In addition, the pore size distribution and change characteristics of the coal samples before and after desorption are analyzed quantitatively via a low-temperature liquid nitrogen adsorption test and fractal dimension-related theory. It was found that the pore volume peak area of the coal samples affected by desorption damage within each pore size range was significantly larger than that before desorption. Among them, micropores have the most significant impact on the desorption damage of coal samples, and the peak area of the pore volume of protruding coal is greater than that of raw coal, indicating that the internal pores of coal after desorption damage are more developed than those of raw coal.

“…Porous organic polymers (POPs), which are composed of lightweight elements linked by strong covalent bonds, have become a research hotspot in recent years [1][2][3][4][5][6][7][8]. As a result of their large specific surface area, tunable pore sizes, and good thermal and chemical stability, POPs are extensively applied in various fields, such as gas storage and separation [9][10][11][12], pollutant removal [13][14][15][16][17], organic electronics [18][19][20], heterogeneous catalysis [21][22][23][24][25], etc. In order to endow them with new functionalities, the design and synthesis of POPs bearing novel structural motifs, especially polycyclic aromatic cores, is highly desired.…”

A new triazaisotruxene-based porous organic polymer (POP) was designed and successfully synthesized by a FeCl3-promoted crosslinking reaction. As a result of its porosity and good thermal stability, the designed POP can be utilized as a promising adsorbent for iodine, not only in the gaseous phase, but also in organic and aqueous solutions. Compared to its triazatruxene (TN) analogue, the ITN-based POP shows equal iodine uptake in the gaseous phase and in hexane solution, and better uptake in aqueous solution.
