Abstract
Official abstract text for this publication.
An oxygen evolution reaction catalyst is a ternary metal oxide that includes Mn and is represented by Mn u Sb v O w in the rutile crystal phase and M x Mn y O z where M is selected from the group consisting of Ca, Ni, Sr, Zn, Mg, Ni, Ba, Co and where u/(u+v) is greater than 33%.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electro-oxidation system for oxygen evolution, comprising: a photoanode comprising an oxidation catalyst that includes Mn u Sb v O w in a rutile crystal phase where u is greater than 0, v is greater than 0, w is greater than 0 and u/(u+v) is greater than 33%. 2. The system of claim 1 , wherein u/(u+v) is greater than 55%. 3. The system of claim 2 , wherein u/(u+v) is greater than 55% and less than or equal to 70%. 4. The system of claim 1 , wherein the photoanode includes a catalytic layer on a current collector and the catalytic layer includes the catalyst. 5. The system of claim 4 , wherein the photoanode contacts an anolyte having a pH less than 3. 6. The system of claim 5 , wherein the Mn u Sb v O w catalyzes oxygen evolution. 7. The system of claim 1 , further comprising: a bias source that applies a bias at or below 1.23 V vs RHE to the photoanode during operation of the system so as to generate oxygen. 8. The system of claim 1 , wherein the photoanode absorb light and convert the absorbed light into excited electron-hole pairs during operation of the system so as to generate oxygen. 9. The system of claim 1 , wherein the photoanode catalyze the oxygen evolution reaction during operation of the system so as to generate oxygen.
