Phosphate stabilized PdCoP@Nifoam catalyst for self-pressurized H2 production from the electrochemical reforming of ethanol at 150 °C

We report a highly active ethanol oxidation catalyst (PdCoNifoam) composed of Pd nanoparticles supported on nanostructured Co oxide structures grown on nickel foam. Treatment with phosphorous vapors at high temperature yields a thin coating of phosphate that confers enhanced stability to the electrode operating in an electrolysis cell at 150 °C. A combination of scanning electron microscopy (energy dispersive X-ray spectroscopy) and X-ray photoelectron spectroscopy reveal a 3D nano-flake surface with an external layer of phosphates that prevents Pd dissolution. The PdCoP@Nifoam catalyst was successfully used for ethanol electrochemical reforming at 150 °C with self-pressurization of the H2 produced by the electrochemical reaction.Graphical abstract
