Ultra-pure Pt/C or Pt-alloy/C catalysts
Further, most oxidization of carbon support methods imposes a potential contamination of the final catalyst product with various other unwanted metal ions, which exist in the acid solution used in the reaction or pre-treatment of the support. Even using extreme washing process, the contents of those contamination ions can reach 500 ppm to 1000 ppm in some well-sold commercial fuel cell catalyst products. Considering the contamination of iron, it has the ability to catalyze some intermediate product H2O2 from oxygen reduction reaction on platinum to form hydroxyl radicals, which is known to be a key factor of damaging the proton exchange membrane.
Blue-O Tech Pt-containing nanocatalysts show almost zero contents of any other metals other than the metals that were desired. Blue-O Tech process employees highly purity crystalline precursors and high purity non-aqueous organic solvents. This extreme high purity metallic NPs on carbon support is deemed to surpass other similar catalysts over durability, sustained activity, and safety of application.
