     View Summary

    Increasing the performance of Pt-based electrocatalysts for the oxygen reduction reaction (ORR) is essential for the widespread commercialization of polymer electrolyte fuel cells. Here we show the synthesis of double-layer Pt nanosheets with a thickness of 0.5 nm via the topotactic reduction of 0.9 nm-thick single-layer PtOx nanosheets, which are exfoliated from a layered platinic acid (HyPtOx). The ORR activity of the Pt nanosheets is two times greater than that of conventionally used state-of-the-art 3 nm-sized Pt nanoparticles, which is attributed to their large electrochemically active surface area (124 m² g⁻¹). These Pt nanosheets show excellent potential in reducing the amount of Pt used by enhancing its ORR activity. Our results unveil strategies for designing advanced catalysts that are considerably superior to traditional nanoparticle systems, allowing Pt catalysts to operate at their full potential in areas such as fuel cells, rechargeable metal–air batteries, and fine chemical production.

  • Synthesis of three-dimensional architecture composed of two-dimensional nanowalls

     View Summary

    In this study, a new electrocatalyst with a three-dimensional architecture composed of a framework of NiO nanowalls was prepared. The electrocatalytic activity of three-dimensional architecture was higher than that of nanoparticles. The result strongly indicates that the 3D structure with 2D nanowall is a superior design for electrocatalyst. Considering the diffusion path of evolved molecules, the enhanced activity could also be attributed to the meso pore nature of 3D-NiO.
