] 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.
(Google Patents says "M03P", the PDF says "MO3P" in the abstract, but the text clearly has "Mo3P".)
Even if this isn't exactly the technology discussed - Supplementary Figure 20 shows how ImF-Mo3P catalyst improves on "pristine Mo3P nanoparticles" - the authors have several other related patents, so I have no doubt a patent was filed for this technology as well.
They have one in this space: "Methods and devices using tri-transition metal phosphides for efficient electrocatalytic reactions" at https://patents.google.com/patent/US20220154354A1/en with abstract:
