Finally, it can be advantageous for 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 {TAIL ~ the mechanical stability} of the palladium rhodium catalyst mesh elements without interfering with their catalytic function
