CoSe2 nanoparticles embedded MOF-derived Co-N-C nanoflake arrays as efficient and stable electrocatalyst for hydrogen evolution reaction

It is still challenging to develop highly efficient and stable non-noble metal-based electrocatalysts for hydrogen evolution reaction (HER). Herein, CoSe2 nanoparticles embedded Co-N-doped carbon nanoflake arrays ([email protected] NAs) are grown on carbon cloth (CC) through a co-precipitation and annealing process. The [email protected] NAs/CC hybrid electrocatalyst shows superior HER performance with a small Tafel slope of 38 mV dec−1, an...
