Summary: Orthorhombic iron-based fluorosulfate KFeSO4F is a promising cathode material for potassium-ion batteries due to its high capacity, voltage plateau, and unique potassium ion conduction pathway. However, its poor thermostability and low electronic conductivity present challenges for its synthesis and electrochemical performance. In this study, carbon nanotubes (CNTs) were introduced into KFeSO4F microspheres to enhance their electronic conductivity and create high-performance potassium-ion batteries. The KFSF@CNTs/DEG cathode exhibited excellent reversible capacity, high working voltage, and long-term capacity retention. The results demonstrated that the addition of CNTs and the use of diethylene glycol (DEG) contributed to the improved electrochemical performance of KFSF@CNTs/DEG through the formation of microspheres with interwoven CNTs and enhanced structural stability and potassium ion diffusion rate.

Summary: Composite structural supercapacitors (SSC) were manufactured using aerospace-grade composite materials and CNT mat electrodes. A new design methodology was explored where the supercapacitor electrolyte was localized within the composite structure, achieving good electrochemical performance within the active region, whilst maintaining excellent mechanical performance elsewhere. The morphology of these localized SSC designs was characterized and found to be directly correlated with both electrochemical and mechanical performance. One configuration using an ionogel with an ionic liquid electrolyte achieved high energy density and corresponding short beam shear strength, while another configuration with only an ionic liquid electrolyte also achieved high energy density and shear strength. Both configurations provide a combined energy and strength superior to previous results in the literature for composite SSCs.

Summary: A three-dimensional carbon nanofiber (CNF) with Pt/NiCo2O4 alloy nanosheets (Pt/NiCo2O4/CNF) catalyst was fabricated for the oxidation of formaldehyde (HCHO) at room temperature. The CNF structure inhibits the aggregation of NiCo2O4 nanosheets and provides a hierarchically porous structure, facilitating the dispersion of Pt nanoparticles and reactant diffusion. Additionally, the presence of oxygen vacancies from the Pt-loading process enhances the HCHO oxidation. Moreover, the microporous structure of CNF promotes strong HCHO adsorption, leading to accelerated formaldehyde oxidation. The Pt/NiCo2O4/CNF catalyst with 0.5 wt% Pt exhibits excellent HCHO oxidation activity, achieving a conversion of 92.4% in 60 minutes due to the combination of adsorption and oxidation. This study provides insights into the development of CNF-based 3D catalysts for indoor HCHO elimination.
