Abstract:
A noble metal-free catalyst composition obtained by a process comprising:a) preparing an aqueous mixture comprisingi) a salt of at least one base metal (M) selected from the group consisting of the elements having atomic numbers 21-32, 39-42, 48-51, 57-75 and 81-83;ii) phosphate ions (P); andiii) at least one nitrogen source (N); andb) evaporating the aqueous mixture obtained and drying the catalyst composition thus formed at a temperature of about 30 to about 200.degree. C.wherein base metal (M), phosphate (P) and nitrogen (N) are present in the noble metal-free catalyst composition in a molar ratio of M:P:N=1:0.9-1.3:0.9-1.7.
