Chem Commun (Camb). 2020 Oct 11;56(79):11787-11790. doi: 10.1039/d0cc04789a. Epub 2020 Sep 3.

Abstract

We present a novel fuel cell heterogeneous catalyst based on rhodium, nickel and sulfur with power densities 5-28% that of platinum. The NiRhS heterogeneous catalyst was developed via a homogeneous model complex of the [NiFe]hydrogenases (H2ases) and can act as both the cathode and anode of a fuel cell.
