Claims29
A water oxidation catalyst splitting water into oxygen and hydrogen ions comprising:
- lithium cobalt germanate.
An oxygen evolution catalyst splitting water into oxygen and hydrogen ions comprising:
- lithium cobalt germanate.
An electrode for electrochemical water oxidation splitting water into oxygen and hydrogen ions comprising:
- a substrate;
- an active material in contact with the substrate, the active material including lithium cobalt germanate;
- wherein water is split into oxygen and hydrogen ions.
A process for oxidizing water comprising the steps of:
- providing an electrode including lithium cobalt germanate;
- providing water and a supporting electrolyte;
- and
- placing the water and supporting electrolyte into contact with the lithium cobalt germinate with an applied oxidative over-potential catalyzing the oxidation of water into oxygen and hydrogen ions.
A process of forming a water oxidation catalyst including the steps of:
- providing LiOH;
- providing GeO2;
- combining the LiOH and GeO2 forming a first solution;
- providing CoCl2 in a solvent;
- combining the first solution and CoCl2 in solvent forming a second solution;
- exposing the second solution to a hydrothermal reaction forming Li2CoGeO4.
