MOF-Derived Pt/ZrO₂ Carbon Electrocatalyst for Efficient Hydrogen Evolution

Abstract

One type of porous carbon nanomaterial decorated by abundant Pt/ZrO2 nanoparticles can be conveniently prepared, which is pyrolyzed from flower-shaped Zr-based UiO-67 precursor with a small amount of H2PtCl6 molecules in its large pores. In addition, the obtained Pt/ZrO2 carbon electrocatalyst can bring efficient electrocatalytic hydrogen evolution performance and long-term stability.

Monodispersed PtCo alloy nanoparticles with a modulated d-band center exhibiting highly efficient hydrogen evolution

“…26 Since PtCo alloys are seriously inuenced by the anchoring substrate, porous carbon with a large specic surface area and abundant pores act as an ideal support to anchor alloy nanoparticles through moderate van der Waals forces. [27][28][29][30] Metalorganic framework (MOF) derived carbon nanomaterials provide a stable framework that effectively anchors and supports alloy nanoparticles, reducing aggregation and enhancing long-term stability. [31][32][33] Among them, zeolitic imidazolate frameworks (ZIFs) stand out as excellent precursors for tailor-made carbon due to their vast surface area, diverse pore diameters, and abundant nitrogen content.…”
