Summary: By using an organocatalytic polymerization method, well-defined amphiphilic block copolyethers can be prepared and applied as structure-directing agents in a standard soft templating process to deliver ordered mesoporous carbons with monomodal and narrowly distributed pore diameters. Selective tuning of pore diameters in the range of 6-18 nm is achievable by judiciously choosing the properties of the structure-directing agents, potentially reducing the effort required to obtain systematically altered materials.

Summary: In this study, an acid-free green synthesis strategy was proposed for the one-pot synthesis of highly ordered mesoporous materials via the radical route with singlet oxygen promotion. The synthesis approach overcomes the challenge in the direct one-pot acid-free synthesis of highly ordered materials and provides a facile and environmentally friendly route for the future large-scale production of ordered mesoporous materials.

Summary: A new and rapid synthetic route for N-doped ordered mesoporous carbon structure was reported by preferential heating of iron oxide nanoparticles by microwaves. The well-defined cubic mesoporous carbon structure showed remarkable improvement in hydrogen desorption kinetics as a host scaffold for NaAlH4, attributed to their ordered pore structure and N-doping effect.

Summary: Conventional ordered mesoporous carbon (OMC) production requires long processing times, but this work demonstrates accelerated synthesis of OMCs using dielectric barrier discharge plasma, achieving carbonization within 15 minutes. The use of plasma enables faster production rates and does not require additional substrates within the OMC precursor systems.

Summary: The alcohol-soluble fraction of humins can be directly transformed into ordered mesoporous carbons (OMCs) using the solvent evaporation-induced self-assembly (EISA) method. The resulting OMCs have well-defined mesoporous structures and high adsorption capacity for macromolecular organic pollutants.

Summary: Incorporation of magnesium nitrate into the precursors during the synthesis of ordered mesoporous carbons improved pore uniformity and volume. The addition of magnesium nitrate lowered the melting point of resorcinol, increased diffusivity, and promoted self-assembly. It resulted in a modification of the pore structure and prevented shrinkage under high-temperature conditions, enhancing uniformity and mesopore volume. This novel method also significantly increased the capacity of electric double-layer capacitors.

Summary: The study introduces a new method for evaluating pore structures in carbon materials, using high-pressure CO2 adsorption isotherms to determine the pore size distribution in both micro- and mesopores. By utilizing Monte Carlo simulations and meso-canonical ensemble methods, capillary condensation transitions in mesopores were successfully predicted, demonstrating the feasibility of the technique in micro-mesoporous carbon materials.

Summary: N/S-doped carbon materials show great promise for the oxygen reduction reaction (ORR), and the key to enhancing their performance lies in constructing uniform doping with desirable configurations and engineering the pore structure. A single-precursor design and a solvent-free nanocasting approach were utilized to synthesize N/S/O-doped ordered mesoporous carbons with high surface areas, large pore volumes, and excellent ORR performance.

Summary: D-glucosamine was used as a non-toxic and sustainable C/N source to synthesize nitrogen-containing CMK-8 ordered mesoporous carbons. The resulting NOMCs exhibited large surface area and excellent pore ordering, with high CO2 adsorption capacity and selectivity under various conditions. The combination of a suitable C/N precursor and hard templating synthetic route proved effective in obtaining high-performing, sustainable, and reusable selective CO2 sorbents.

Summary: The influences of porous carbon's physicochemical properties on CO2 adsorption at different pressures were investigated in this study. N-doped hierarchically ordered micro-mesoporous carbons (NHOMCs) were synthesized and their characteristics and CO2 uptake were analyzed. The results showed that NHOMCs exhibited high CO2 adsorption capacity and the adsorption performance was correlated with the physicochemical properties of the materials.

Summary: Mesoporous carbons with highly ordered body centred cubic (bcc) arrangement of pores were prepared using a halide- and metal-free synthesis method. The materials had Specific Surface Areas ranging from 422 to 988 m(2)g(-1) and pore diameters around 7 nm, with high quality Digital Diffraction Patterns obtained from TEM images related to the ordered mesopore structure. The structure and texture of the materials were influenced by polymerisation time and the concentrations of NH4OH and oxalic acid catalysts, with shorter polymerisation times and lower catalyst concentrations resulting in the most well-ordered products.

Summary: A coarse grained lattice gas model is proposed for analyzing the thermodynamics and dynamics of adsorption and desorption in three dimensionally ordered mesoporous carbons. The study shows that the model accurately describes experimental behavior, particularly highlighting the important effect of the spherical geometry of the pores on hysteresis behavior.
