Pyrolysis process of precursors at low temperatures critically influences the HC structure by modulating the transformation of gas, liquid, and solid phases, yet its mechanistic impact remains poorly understood. Herein, the heating rate during low-temperature pyrolysis is investigated for the HC structure evolution and Na-ion storage performance. By increasing the heating rate, the thermochemical kinetics of pyrolysis process can be enhanced, facilitating non-carbonaceous (H, O, etc.) atom removal. When an ultrafast heating rate is applied, high pyrolysis kinetics promote the generation of thermally stable ester functional groups, thereby inhibiting the aromatic aggregation and facilitate to form random carbon skeleton. Furthermore, the ester functional groups decompose into volatiles at high-temperature carbonization, resulting in porous structure suitable for Na-ion storage. The optimized HC achieves a reversible capacity of 426.2 mAh g<sup>−1</sup> with an initial Coulombic efficiency of 88.7 %.

In contrast to conventional electrochemical oxidation of graphite, which yields rough surfaces, CEEL produces mechanically robust, vivid photonic structures with intense structural colors.

Second, we \"rewrite\" these films with a tightly focused laser to produce laser-reduced graphene oxide (LrGO) vertical interconnects. This enables us to draw all-carbon free-form, high-resolution LrGO circuits within the larger, electrochemically defined GO structure. Finally, we exploit this hierarchical control to \"direct\" the selective assembly of plasmonic nanostructures onto the LrGO patterns, integrating plasmonic microreactors and chemical sensing capabilities.
