Spike‐Embedded Nanocatalysts via Metal‐Directed Carbonization for Highly Efficient and Robust Semi‐Hydrogenation

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
A metal‐directed carbonization strategy transforms hierarchical organic microspheres into spiky carbon catalysts with Pd nanoparticles embedded at the tips. This approach resolves the activity‐stability trade‐off, achieving exceptional poison resistance in semi‐hydrogenations, offering a versatile, scalable platform for designing high‐performance ...

The Role of Native Binder in Controlling the Polytetrafluoroethylene Distribution in Gas Diffusion Layers for Proton Exchange Membrane Fuel Cells

open access: yesFuel Cells, Volume 26, Issue 4, August 2026.
ABSTRACT Gas diffusion layers (GDLs), a critical component in H2${\rm H}_{2}$/O2${\rm O}_{2}$ proton exchange membrane fuel cells (PEMFCs), are commonly treated with polytetrafluoroethylene (PTFE) for controlling hydrophobicity. However, the influence of the GDL's native microstructure on the final PTFE spatial distribution is still poorly understood ...
