Ruthenium and cobalt bimetal encapsulated in nitrogen-doped carbon material derived of ZIF-67 as enhanced hydrogen evolution electrocatalyst

Due to the high price and low reserve of platinum (Pt) base precious catalysts, and non-noble metal catalysts are unable to catch up with the overpotential of Pt-based electrocatalysts, more and more attention has been paid to study low-noble metal catalysts. In this work, we report a highly active and steady electrocatalyst with ruthenium and cobalt bimetal encapsulated in nitrogen-doped carbon material derived of ZIF-67. ZIF-67 was firstly...
