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