Single source precursor route for the first graphene oxide-Pd 6 P nanocomposite: application in electrochemical hydrogen evolution reaction

For the first time, Pd P has been synthesised using a simple, straightforward and one-pot method , thermolysis of a Pd(II) complex of a bidentate (P, N) organophosphorus ligand (anthracene-9-yl-CHN-CH CH -PPh ). The electrocatalyst (obtained after grafting nanospheres of Pd P over layers of graphen...

Description
Summary:For the first time, Pd P has been synthesised using a simple, straightforward and one-pot method , thermolysis of a Pd(II) complex of a bidentate (P, N) organophosphorus ligand (anthracene-9-yl-CHN-CH CH -PPh ). The electrocatalyst (obtained after grafting nanospheres of Pd P over layers of graphene oxide) shows high activity in electrochemical hydrogen evolution reactions (HER) with an overpotential of 133 mV to drive 10 mA cm of cathodic current density. The GO-Pd P nanocomposite is robust and effective for a continuous HER run for up to 16 hours.
