Ruthenium is often alloyed with platinum or palladium primarily to:

improve corrosion to make it soluble

harden and improve wear resistance of contacts

make the alloy more radioactive

Which catalytic application is ruthenium commonly used for in homogeneous or heterogeneous form?

Olefin metathesis and hydrogenation

Primary fuel for internal combustion engines
