• Delafossite - Wikipedia

    en.wikipedia.org/wiki/Delafossite Delafossite is a copper iron oxide mineral with formula CuFeO 2 or Cu 1+ Fe 3+ O 2.It is a member of the delafossite mineral group, which has the general formula ABO 2, a group characterized by sheets of linearly coordinated A cations stacked between edge-shared octahedral layers (BO 6). Delafossite, along with other minerals of the ABO 2 group, is known for its wide range of electrical ...

  • Achieving delafossite analog by in situ electrochemical ...

    www.pnas.org/content/117/36/21906 Electrochemical water splitting to generate hydrogen and oxygen is proposed as a promising way for building a clean-energy future. One of the challenges facing this scenario is to develop robust electrocatalysts, especially for the kinetically sluggish oxygen evolution reaction (OER) process. In this work, the delafossite analog was proposed by mutation of metal oxyhydroxides and delafossite.

The values of the quantum efficiency are similar (ca. 0.6%) under light ...
