Abstract: The invention relates to aprocess for producing a catalyst comprising an intermetallic com-pound comprisingmixing of a salt comprising a metal selected from the group consisting of Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Auand Ru, a salt comprising a metal selected from the group consist-ing of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba,Sc, Y, La and the lanthanides, and a reducing agentcomprising a salt,wherein the mixing is carried out at a temperature where all compo-nents are solid; reacting the mixture obtained to form an intermetallic compound by heating said to a temperature in the range between the melting temperature of thereducing agent and the melting temperature of the intermetallic compound and holdingthe temperaturefor1 minute to 600 minutes; and washing the mixture to removeby-products andremainders of the salt of the cations of the reducing agent and at least one of the anions of the salts used in the first step. The invention further relates to a catalyst obtained by the process.
