摘要: A hybrid three dimensional (3D) hydrogen evolution reaction (HER) catalyst that is formed from a porous Ni foam support, a NiSe2 scaffold positioned on the support; and layered transition metal dichalcogenide (LTMDC) or first-row transition metal dichalcogenide particles positioned on the NiSe2 scaffold. The catalyst provides a low onset potential, large cathode current density, small Tafel slopes, and large exchange current densities, similar in catalytic power to Pt HER catalysts.

摘要: An electrochemical hydrogen compression apparatus and a method for the collection and compression of hydrogen. The apparatus includes a cathode having a surface that is modified with a Tafel inhibitor that inhibits the Tafel reaction at the cathode surface. The same cathode surface may also include a Volmer catalyst to enhance the Volmer reaction at the cathode surface. The apparatus and method can advantageously increase the pressure of collected hydrogen, and may be useful for supplying the hydrogen to energy producing devices, such as a fuel cell.
