Templated N‐Doped Carbon Nanospheres with Tailored Porosity for High Performance PEM Fuel Cell Catalysts Under a Wide Range of Conditions

Advanced Energy Materials, EarlyView.
Monodisperse mesoporous N‐doped carbon nanospheres (MPNCs with 10 and 28 nm pores, >100 nm particle sizes) are used as advanced supports for Pt‐based PEMFC cathode catalysts. Their tailored intra‐ and interparticle porosity boosts oxygen transport and mass activity.

Addressing Degradation of Ni/YSZ Cermet Fuel Electrode in Reversible Solid Oxide Cells

Advanced Energy Materials, EarlyView.
Infiltrating nanostructured ceria (CGO) into Ni/YSZ electrodes significantly enhances durability in reversible solid oxide cells. Performance remains stable over 650 h and 24 redox cycles at 750 °C, despite Ni agglomeration. This approach shifts electrochemical activity toward CGO surfaces and reduces reliance on microstructure optimization, offering 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.
