  • Metal-doped tin oxide for electrocatalysis applications
    Patent number: 11110433
    Abstract: The present invention relates to a metal-doped tin oxide which has a BET surface area of at least 30 m 2/g, and comprises at least one metal dopant which is Sb, Nb, Ta, Bi, W, or In, or any mixture thereof, wherein the metal dopant is present in an amount of from 2.5 at % to 25 at %, based on the total amount of tin and metal dopant atoms, and is in a mixed valence state containing atoms of oxidation state OS1 and atoms of oxidation state OS2, wherein the oxidation state OS1 is >0 and the oxidation state OS2 is >OS1 and the atomic ratio of the atoms of OS2 to the atoms of OS1 is from 1.5 to 12.0.
    Type: Grant
