Front Cover:Tuning Structure and Properties of Pt Catalysts Confined in Single‐Walled Carbon Nanotubes (SWNTs) for Electrocatalysis (ChemNanoMat 3/2023)

The structure of Pt nanocatalysts confined in single-walled carbon nanotubes (SWNTs) can be tuned through a facile two-step process in which Pt was firstly co-filled with different ratios of Co in SWNTs and followed by acid treatment to remove Co. The resulting Pt nanocatalysts can function efficiently for two typical electrocatalytic applications of hydrogen evolution and hydrogen sensing, and the correlation between structure and catalytic activity was demonstrated. The approach provides a general route to tune structure and properties of metal catalyst confined in carbon nanotubes for applications in the H2 energy industry and other fields.
