1. Ịrụ ọrụ dị elu: Nano platinum particles nwere ebe dị elu dị elu na ebe ndị na-arụ ọrụ, n'ihi ya, ha nwere ike nweta mmeghachi omume catalytic dị mma na obere okpomọkụ na nrụgide dị ala. Nke a na-ebelata ike oriri na mmeghachi omume mkpofu mmepụta, na-eme Pt nanoparticles dị mma maka akwụkwọ ndụ akwụkwọ ndụ catalysis.
2. Ntughari: E jiri ya tụnyere omenala omenala, nano Pt powders nwere nkwụsi ike ka mma na recyclability. Enwere ike iji ha ọzọ site na nkewa dị mfe na imegharị ihe, si otú ahụ belata oriri na-akpali akpali na mmetọ gburugburu ebe obibi.
3.
