Summary: The fabrication of low-cost, effective, and highly integrated nanostructured materials for high-energy-density supercapacitors is highly desired. In this study, an activated carbon cloth (ACC) is designed as the functional scaffold for supercapacitors and modified with various nanomaterials. The resulting structured core-shell heterostructure ACC@NiCo@NiOOH@CoMoO4 electrode exhibits exceptional specific areal capacitance and cycling stability. Moreover, this electrode is developed into an asymmetric supercapacitor, demonstrating excellent areal capacitance, energy density, and power density with a high cycling life.

Summary: Co@C/CC immobilized catalyst shows enhanced catalytic activity and lower Co ion leaching in persulfate activation for organic pollutant degradation. The Co@C/CC/PMS system efficiently degrades tetracycline with high durability, interference resistance, and wide pH adaptability. Non-free radical pathway (1O2) dominates the degradation process. Density functional theory calculations indicate C-C as the primary attack site in tetracycline and provide possible degradation pathways. Importantly, the Co@C/CC catalyst enables fast and simple collection and regeneration.
