Tangfeng develops platinum-carbon, platinum-cobalt alloy, platinum core-shell and iridium oxide catalysts. Pt/C catalysts combine oxygen reduction activity with support durability. Pt-Co alloy catalysts offer high catalytic activity and resistance to potential-dynamic dissolution. Platinum core-shell catalysts use an ultrathin Pt shell design to improve platinum atom utilization. IrOx catalysts feature high specific surface area and uniform distribution of iridium oxide nanoparticles for PEM water electrolysis applications.
