Finally, it can be advantageous for the palladium rhodium mesh to contain an additional metal from {HEAD ~ the group} consisting of {TAIL ~ iridium}, ruthenium, rhenium, cobalt, nickel, copper, and gold to increase the mechanical stability of the palladium rhodium catalyst mesh elements without interfering with their catalytic function
