Abstract

Abstract Bifunctional catalysis for water splitting is for the first time realized on Ru noble metal in the form of crystallized RuTe2 nanoparticles on graphene. Super activity to the state-of-the-art Pt and RuO2 is found for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) because of the high degree of crystallinity, uniform distribution of nanoparticles, and electronic effect in the catalyst system. It offers a low cell voltage of 1.57 V to drive 10 mA cm−2, 100 mV lower than that of Pt/C-RuO2 benchmark electrodes in an alkaline electrolyte, along with a pretty good chemical and structural stability in the strong corrosive environment. The theory calculation confirms the superior intermediates adsorption property because of the Ru/Te synergism, and Pt like/RuO2 like character for water splitting reaction. It is a very promising catalyst in the alkaline electrolyzer due to the reliable catalytic ability and relatively low price (1/4 Pt).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
