Abstract (en)

Novel rhodium based amorphous metal alloys having the formula RhrAa where: A is B, P, As and mixtures thereof; r is from about 50 to 96 percent; and a is from about 4 to 50 percent. Novel rhodium based amorphous metal alloys are also based on the formula RhrBbDd where: D is Ir, Pd, Ru, Ti, Zr, Nb, Ta, Y, Hf and mixtures thereof; r is from about 50 to 96 percent; b is from about 4 to 50 percent; and d is from about 0 to 60 percent; and r + b + d = 100. Novel process for the generation of halogens from halide-containing solutions can be performed by employing the rhodium based metal alloys of the present invention.
