Not any kind of chemist, but I'm seeing molybdenum disulfide plus (metal) coated on alumina support used as a catalyst, as well as magnetic Al/Fe composite nanoparticles used for same. Usually the metal is something more punk rock, like platinum, cobalt, or ruthenium, but copper is an obvious choice on the poisonous/cheap axis
