In a water electrolysis system, the cathode and anode produce H 2 and O 2 with HER and
OER, respectively. The energy conversion efficiency of the electrolysis systems is about 56 …

Electrochemical hydrogen evolution via water splitting has been regarded as a highly
promising technique for fossil-fuel substitution in the future to avoid environmental pollution …

The microstructure of active centers in bimetallic/multimetallic catalysts is under a long-time
debate toward oxygen evolution reaction (OER). Here, sulfur doping NiFe 2 O 4 nanocone …

This research investigates the hydrothermal synthesis and annealing duration effects on
nickel sulfide (NiS 2) quantum dots (QDs) for catalytic decolorization of methylene blue (MB) …

The inferior performance of non-precious metals on electrocatalytic hydrogen evolution can
be mainly attributed to the inappropriate adsorption strength of intermediates. A core–shell …

The exploration of efficient metal-based bifunctional catalysts for electrochemical water
splitting is a promising approach for large-scale applications. In this work, we constructed a …
