Summary: Lignin-derived carbon electrode materials with a high carbon content and a rich benzene ring structure were studied for supercapacitors, and it was found that the nanoporous structure significantly affects the capacitive performance. Three nitrogen-doped nanoporous carbons were prepared using alkali lignin as a carbon source, and the effect of different nanopore distributions on the electrochemical performance was examined. The carbon activated by ZnC2O4 showed a hierarchical porous structure composed of nanosheets, enabling it to store charge and transfer ions simultaneously. It achieved a maximum specific capacitance of 254F/g at 0.5 A/g, surpassing the microporous-dominated carbon activated by K2CO3 and mesoporous-dominated carbon obtained by the SiO2 template method. This study provides theoretical guidance for the preparation of excellent lignin-derived carbon electrode materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
