Abstract
The present description relates to metal alloy electrocatalysts, preferably composed of Ni and Co as transition metals and Se as a chalcogen. The electrocatalysts can take the form of nanochalcogenides that can be made using cryogenic milling followed by surfactant-assistant milling. The electrocatalysts can be used in the context of water electrolysis or electroreduction of CO2 gas into carbon based products.
