A cathode is provided for electrolysis of water wherein the cathode material comprises a multi-principal element, transition metal dichalcogenide material that has four or more chemical elements and that is a single phase, solid solution. The pristine cathode material does not contain platinum as a principal (major) component. However, a cathode comprising a transition metal dichalcogenide having platinum (Pt) nanosized islands or precipitates disposed thereon is also provided.

Electrocatalyst for water electrolysis

A method embodiment involves preparing single metal or mixed transition metal chalcogenide using exfoliation of two or more different bulk transition metal dichalcogenides in a manner to form an intermediate hetero-layered transition metal chalcogenide structure, which can be treated to provide a single-phase transition metal chalcogenide.

Preparation of metal chalcogenides

Certain method embodiments are described and useful for recycling permanent magnet materials (e.g. permanent magnet alloys) and battery materials (e.g. battery electrode materials) to extract critical and/or valuable elements including REEs, Co and Ni. Method embodiments involve reacting such material with at least one of an ammonium salt and an iron (III) salt to achieve at least one of a liquid phase chemical reaction and a mechanochemical reaction.

Chemical dismantling of permanent magnet material and battery material

In some examples, a method of forming alane (AlH), the method comprising reacting one of: 1) a MAlH, wherein M is an alkali metal; 2) alkali-metal hydride, MH; or 3) alkali-metal with one or more aluminum halides (AlX, where X is a halogen), via a mechanochemical process, to form the alane, wherein the reaction is substantially solvent free and carried out in an environment with a temperature between approximately 250 K and approximately 330 K.

Mechanochemical synthesis of alane

A method is provided for making alkali metal hydrides by mechanochemically reacting alkali metal and hydrogen gas under mild temperature (e.g room temperature) and hydrogen pressure conditions without the need for catalyst, solvent, and intentional heating or cooling.
