Carbon supported catalyst comprising a modifier and process for preparing the carbon supported catalyst

A carbon supported catalyst comprising

• a carbon-comprising support with a BET surface area in a range from 400 m2/g to 2000 m2/g,
• a modifier comprising:
• at least one mixed metal oxide, comprising niobium and titanium;
• a mixture comprising niobium oxide and titanium oxide;
• or
• at least one mixed metal oxide comprising niobium and titanium and a mixture comprising niobium oxide and titanium oxide;
• a catalytically active metal compound, wherein the catalytically active metal compound is platinum or an alloy comprising platinum and a second metal or an intermetallic compound comprising platinum and a second metal, the second metal being selected from the group consisting of cobalt, nickel, chromium, copper, palladium, gold, ruthenium, scandium, yttrium, lanthanum, niobium, iron, vanadium and titanium,
• wherein the carbon supported catalyst comprises 0.5% to 20% by weight of niobium and 0.5% to 10% by weight of titanium.
