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

open access: yesAdvanced 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.

Advancing Direct Alcohol Fuel Cells: Innovations in Composite‐Based Electrocatalysts and Polymer Support Materials for Enhanced Efficiency

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This graphical abstract emphasizes the working principle and the various essential factors of the direct methanol fuel cell (DMFCs). Additionally, various parameters, such as the nanoparticle's size and shape, the nature of the electrolyte, the type of support materials, and their fabrication process, also play essential roles in the functioning of the

Sulfonated Diels–Alder Poly(Phenylene)s in Membrane Electrode Assemblies for Fuel Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study reveals that ionomer adsorption is the key performance‐limiting factor for sulfonated Diels–Alder poly(phenylene)s in fuel cell cathodes, with interfacial incompatibility and hydrophilicity also contributing. High performance is retained in membranes and anodes, but significant losses occur when used as cathode binders.
