Reverse microemulsion prepared Ni–Pt catalysts for methane cracking to produce COx-free hydrogen

Abstract

A monodispersed 15 nm Ni₉Pt₁ catalyst synthesized via a reverse microemulsion method, shows a lower activation energy than both Ni and Pt catalysts during the methane cracking reaction. Thanks to the synergic effect of Ni–Pt alloy, this catalyst presents a stable H₂ formation rate at 700 °C, and forms carbon nanotubes, anchoring the catalyst particles on top.
