Synthetic Engineering of Manganese Oxide–Carbon Nanocomposites for Maximized Metal Utilization in Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐pot metal–ammonia synthesis enables uniform Mn2O3 nanoparticle deposition on activated carbon, yielding composites with excellent electrochemical performance in supercapacitors. The method maximizes manganese utilization, eliminates toxic solvents, and achieves 34% of the theoretical maximum capacitance, significantly outperforming existing Mn–C ...

Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their

Synergistic SnSe2@Ti3C2Tx MXene Heterostructured Separator for Highly Efficient Polysulfide Adsorption, Catalytic Redox Acceleration, and Enhanced Electrochemical Stability in Advanced Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional SnSe2@MXene heterostructure coated on a separator serves as a catalytic interlayer in Li‐S batteries. This design synergistically integrates the strong polysulfide adsorption and catalytic activity of SnSe2 with the high electrical conductivity of the MXene matrix, effectively suppressing the shuttle effect and enabling long‐term ...
