N-rich porous organic polymers based on Schiff base reaction for CO2 capture and mercury(II) adsorption

Nitrogen‐rich melamine cyanurate derived hollow porous carbon microspheres prepared through CuCl2 activation for VOCs adsorption

“…[32] Besides, the rise at narrow relative pressure from 0.9 to 1 implies NPC-800-4 also poses a portion of macopores. [33] This hierarchical porous structure is more clearly illustrated in Figure 3c and Figure 3d. For the NPC-800-0 sample without CuCl 2 activation, the pore diameters mainly distribute at the range of 0.7-1.5 nm and 2.3-30 nm.…”

Freundlich Isotherm: An Adsorption Model Complete Framework

“…Thus, the use of Equations ( 4) and ( 5) enables one to perform this without an introduction of a rigorous boundary between the saturation regime (grey curves) and the intermediate Freundlich isotherms in all concentration ranges. Blue f 1 (x): experimental data (a) [6]: the source graphical data were digitalised for further analysis; (b) [9]: available supplementary digital data were used). Grey f 3 (x): saturation regimes according to Equation (4).…”

“…The Dubinin-Radushkevich AM is to be mentioned again as well but this is more applicable for adsorption on materials with pronounced porous properties). A huge variety of realizations of the Freundlich AM, among whose are the works having studied the adsorption of organic and inorganic substances on substrates of different nature in the framework of chemical, physical, biophysical processes including nano-particles as just examples [2][3][4][5][6][7][8][9][10], seems to represent a substantial reason for revisiting the basics of the Freundlich AM. While the monograph by McBain first convincingly elucidated the meaning of Equation (1) for interpretation of experimental data [11], the proper theoretical model was developed by Zeldowitch (1934) [12,13], and later reproduced as one of parametrical limits while expanding the general solution for energetically heterogeneous surfaces, expressed through a hypergeometric function into an infinite series [14,15].…”

Two mono‐ and dinuclear Cu (II) complexes derived from 3‐ethoxy salicylaldehyde: X‐ray structures, spectroscopic, electrochemical, antibacterial activities, Hirshfeld surfaces analyses, and time‐dependent density functional theory studies

“…Due to the flexibility and variability of Schiff bases in terms of structure and physical and chemical properties, it has become an attractive research object. [ 1,2 ] Schiff bases form metal complexes with various structures under certain conditions, [ 3–5 ] and these complexes have distinguished roles in photovoltaic materials, [ 6 ] magnetism, [ 7 ] nanomaterial catalysts, [ 8,9 ] capture performance, [ 10 ] nonlinear optical properties, [ 11 ] chemical sensors, [ 12,13 ] fluorescent materials, [ 14 ] and antiviral activity and other fields. [ 15,16 ] Quinazoline has the skeleton of a variety of alkaloids, its derivatives have multiple biological activities and show unusual high affinity for metal ions, also form all kinds of coordination compounds with many transition metals.…”
