TLDR
In this paper, a top-down chemical reaction-induced dispersion process using rh nanoparticles as the starting materials was used to construct a single-atom catalysts supported on activated carbon (Rh1/AC).Abstract:
Rhodium (Rh) single-atom catalysts (SACs) supported on activated carbon (Rh1/AC) are prepared via a “top-down” chemical reaction-induced dispersion process using Rh nanoparticles as the starting materials. The as-obtained Rh1/AC exhibits hydrogen evolution activity and stability much better than those of the state-of-the-art Pt/C catalysts in alkaline solutions.read more
