Mature passive films (age > 10 s) were grown in aerated saturated calcium hydroxide solution, at the open circuit, on plain steel and alloys with 9% and 22% Cr, as well as austenitic stainless steels. The materials were commercially produced concrete reinforcing steels. Differences in the polarization of the oxygen reduction reaction were evidenced. Oxygen reduction rates at moderate cathodic p...

The metal–support interaction between Ni and VN contributes to an outstanding performance for Ni/VN towards hydrogen evolution electrocatalysis following the Volmer–Tafel mechanism.

The hydrogen evolution reaction (HER) via water splitting requires the development of advanced and inexpensive electrocatalysts to replace expensive platinum (Pt)-based catalysts. The scalable hydrothermal synthesis of SnS on N-reduced graphene (N-rGr) sheets is presented for the first time, which is used as a highly-active electrocatalyst with long-term stability in acidic, neutral, and alkali...
