Figure 6. (A) Schematic diagram of the closed-pore formation mechanism in the pyrolysis process of ZG^[140] (Copyright 2024, American Chemical Society). (B) Schematic synthetic procedure at macroscopic and molecular level. (i) Molecular structure of PEO_n-b-PHA_m block copolymers. (ii) Schematic representation of initial precursor dispersion with fixed mass ratios of template, carbon precursors, and aqueous glyoxal solution (1.731:1:1.216). and (iii) molecular assembly due to hydrogen bonding interaction. Furthermore, (iv) ordered mesophase after the EISA process and thermopolymerization with (v) the resulting covalent bonding. (vi) Mesoporous carbon after carbonization at 900 °C, respectively 1,300 °C, in a nitrogen atmosphere^[141] (Copyright 2023, American Chemical Society).
