Abstract
Methods and devices for generating hydrogen gas with an electrocatalytic energy conversion cell by introducing a tri-transition metal phosphide catalyst at or on an electrode of the electrocatalytic energy conversion cell. The electrocatalytic energy conversion cell includes a first electrode including a tri-transition metal phosphide catalyst, such as Mo3P, a second electrode of an anodic material, an electrolyte disposed between the first electrode and the second electrode, and an electric potential source connected to both electrodes. Oxidation and reduction reactions, such as hydrogen evolution reactions, occur at the first electrode.
Claims13
A method of generating hydrogen gas, comprising:
- providing an electrocatalytic energy conversion cell comprising a first electrode including a tri-transition metal phosphide catalyst, a second electrode comprising an anodic material, and an electrolyte disposed between the first electrode and the second electrode, wherein the catalyst is selected from the group consisting of Zr3Pm, Hf3Pm, Ta3Pm, Tc3Pm, and Re3Pm, wherein m is independently one of 1, 2, 3, 4 or 5;
- applying an electrical potential to the first and second electrodes;
- reducing hydrogen ions in the electrolyte at the first electrode;
- and
- collecting the hydrogen gas.
