“…This was explained by the fact that, upon contact of MCPCM@La 2 O 2 CO 3 with MB solution, where surface adsorption originally occurred, MB molecules rapidly migrated in a significant number of micropores and mesopores. This explains the steep initial slope and the quick adsorption that take place . The NL-DFT analysis estimated an average pore diameter of 2.113 nm.…”

Biochar porous carbon material (BPCM) has extraordinary adsorption properties and is being widely used in different fields around the world. The pore structure of BPCM is liable to collapse, and mechanical properties are inferior; hence, the focus is on developing a new ″powerful″ structure of functional BPCM. Rare earth elements with characteristic f orbitals are used as pore and wall strengthening units in this work. The new ″beam and column structure″ BPCM was synthesized by the aerothermal method, and then, the magnetic BPCM was prepared. The results showed that the designed synthesis route was reasonable, BPCM with a steady-state beam and column structure was attained, and the La element played a stabilizing role in maintaining the overall BPCM. The La hybridization exhibits the characteristic of ″the stronger column and weaker beam″, and the La group is the ″column″ to strengthen the BPCM as the ″beam″. The functionalized BPCM (lanthanum-loaded magnetic chitosan-based porous carbon materials, MCPCM@La2O2CO3) obtained exhibited a transcendent efficient adsorption capacity with an average adsorption rate of 6.640 mg·g–1·min–1 and over 85% removal of different types of dye pollutants, which exceeded the adsorption performance of the materials of most other BPCMs. Ultrastructural analysis revealed that MCPCM@La2O2CO3 has a huge specific surface area of 1458.513 m2·g–1 and a magnetization value of 16.560 emu·g–1 for MCPCM@La2O2CO3. A new theoretical model for the adsorption of MCPCM@La2O2CO3 (multiple adsorption coexistence equation) was established. The theoretical equations clarify that the mechanism of pollutant removal by MCPCM@La2O2CO3 is different from the traditional adsorption model, presenting a mechanism of coexistence of multiple adsorption types, displaying a monolayer–multilayer adsorption mechanism, influenced by the synergistic effects of H bonding, electrostatic attraction, π–π conjugation, and ligand interaction. The rapid coordination of the d orbitals of La is an obvious factor in enhancing the adsorption efficiency.

Engineering porous organic polymers (POPs) into 1D morphology holds significant promise for diverse applications due to their exceptional processability and increased surface contact for enhanced interactions with guest molecules. This article reviews the latest developments in nanofibrous POPs and their derivatives, encompassing porous organic polymer nanofibers, their composites, and POPs‐derived carbon nanofibers. The review delves into the design and fabrication strategies, elucidates the formation mechanisms, explores their functional attributes, and highlights promising applications. The first section systematically outlines two primary fabrication approaches of nanofibrous POPs, i.e., direct bulk synthesis and electrospinning technology. Both routes are discussed and compared in terms of template utilization and post‐treatments. Next, performance of nanofibrous POPs and their derivatives are reviewed for applications including water treatment, water/oil separation, gas adsorption, energy storage, heterogeneous catalysis, microwave absorption, and biomedical systems. Finally, highlighting existent challenges and offering future prospects of nanofibrous POPs and their derivatives are concluded.

“…In comparison, adsorption technology is widely used due to its low cost, ease of operation, and high efficiency [ 14 ]. Metal oxides [ 15 ], carbon materials [ 16 ], metalorganic frameworks (MOF) [ 17 ], graphene [ 18 ], zeolites [ 19 ], and polymers [ 20 ] have all been used as adsorbents in the treatment of polluted water. Among them, activated carbon (AC) is one of the most commonly used adsorbents, which is one kind of low-cost adsorbent, and the corresponding adsorption performance is primarily determined by the carbon pore structure, which is derived by the carbon resource and carbonization process.…”

Porous ZnCl2-Activated Carbon from Shaddock Peel: Methylene Blue Adsorption Behavior

It is of great interest and importance to resource utilization of waste biomass to produce porous carbon for environmental treatments. Pore structure and properties of the obtained carbon mainly relate to carbonization conditions and biomass types. In this work, a series of porous, biomass-activated carbons (AC) were prepared using shaddock peel, with ZnCl2 as a pore-forming agent. The effect of carbonization temperature and the mass ratio between ZnCl2 and shaddock peel were thoroughly investigated. The material composition, surface chemical properties, and surface structures of samples were carefully characterized. The specific surface area and adsorption capacity to methylene blue (MB) of adsorbents were changed with the carbonization temperature and the mass ratios between ZnCl2 and shaddock peel; when the temperature was at 1000 °C and the mass ratio was equal to 2:1, the resulting adsorbent had the largest specific surface area of 2398.74 m2/g and average pore size of 3.04 nm, which showed the highest adsorption capacity to MB to be 869.57 mg/g. The adsorption processes of biomass AC adsorbent matched the pseudo-second-order kinetic model and Langmuir isotherm model. This efficient and environmentally friendly biomass AC adsorbent from shaddock peel, activated by ZnCl2, is a promising candidate for the treatment of water pollution.
