MOF derived Co/C and Co3O4/C polyhedron for hydrogen evolution reaction
We have synthesized MOF derived cobalt-polyhedron by facile method and the same was characterized by various spectroscopic and analytical techniques. Prepared polyhedronhas rhombic dodecahedron shape and shows efficient electrocatalytic activity for hydrogen evolution in 0.5M H2SO4 solution. Acid washed (AW) samples shows better HER activity as compared to their only heat-treated counterpart. 900AW show maximum HER activity (Tafel slope 86.9 mV dec-1). It was found that temperature as well as porosity plays very important role in HER.We have synthesized MOF derived cobalt-polyhedron by facile method and the same was characterized by various spectroscopic and analytical techniques.
