Nanoarchitectonics of N‐ and S‐Doped Nanoporous Biocarbons with High Specific Surface Area from Casein and Dithiooxamide for Supercapacitor Applications

Advanced Energy and Sustainability Research, EarlyView.
N, S codoped nanoporous biocarbons are synthesized using casein and dithiooxamide via a low‐cost chemical activation approach. Reasonable high surface areas and concentrations of codopants were observed. This leads to a good capacitance of 178 F g−1 along with good cycling stability of 93.2% retention after 300 cycles, which demonstrates the ...

Metal‐Organic Open‐Framework Molecular Magnet Based on Vanadium Hexacyanoferrate Prussian Blue Analogs as Cathode Material for Advanced Potassium Ion Aqueous Battery

Advanced Energy and Sustainability Research, EarlyView.
An aqueous potassium‐ion battery using vanadium hexacyanoferrate (VHCF) as the cathode and graphite as the anode is presented. During charge/discharge, K+ ions shuttle between electrodes through the electrolyte, enabling energy storage. The VHCF material demonstrates high capacity (≈121 mAh g−1), fast kinetics, and eco‐friendliness, making it a ...

Zero‐Valent Iron Nanoparticles Supported on Si/N Codoped Carbon Materials: From Biomass to Oxygen Reduction Electrocatalysts and Supercapacitors

Advanced Energy and Sustainability Research, EarlyView.
Zero‐valent iron nanoparticles on Si/N codoped carbon support are prepared from hydrothermal carbonization and pyrolysis of biomass, silica, and iron salt. The Fe nanoparticles are evenly distributed on the support and encapsulated in graphitic or iron oxide shells.

Pyrazine‐Embedded 2D Conjugated Metal–Organic Framework with Quasi‐Honeycomb Lattice for High‐Capacitance Lithium‐Ion Storage

Angewandte Chemie, EarlyView.
A Cu‐OHDDQP 2D conjugated metal–organic framework (2D c‐MOF) was synthesized possessing a unique quasi‐honeycomb topology, from a pyrazine‐fused, D2‐symmetric ligand. The achieved 2D c‐MOF electrode displayed a remarkable gravimetric capacitance up to 452 A g−1 for electrochemical lithium storage.
