Litšepe tsa sehlopha sa platinum li kenyelletsa platinum(Pt), rhodium(Rh), palladium(Pd), ruthenium(Ru), osmium(Os), le iridium(Ir), tseo e leng tsa tšepe tsa bohlokoa joalo ka khauta(Au) le silevera(Ag) . Li na le maqhama a matla a athomo a matla haholo, 'me ka hona li na le matla a maholo a tlamahano ea li-interatomic le bongata ba bongata bo boholo. Nomoro ea khokahanyo ea athomo ea litšepe tsohle tsa sehlopha sa platinum ke 6, e khethollang litšobotsi tsa tsona tse ikhethang tsa 'mele le lik'hemik'hale. Litšepe tsa sehlopha sa Platinum li na le lintlha tse phahameng tse qhibilihang, motlakase o motle oa motlakase le ho hanyetsa ho bola, matla a mocheso o phahameng le ho hanyetsa mocheso o phahameng, le botsitso bo botle ba mocheso o phahameng. Litšobotsi tsena li ba etsa lisebelisoa tsa bohlokoa bakeng sa indasteri ea morao-rao le kaho ea tšireletso ea naha, e sebelisoang haholo ho lifofane, sefofaneng, lirokete, matla a athomo, theknoloji ea microelectronics, lik'hemik'hale, khalase, ho hloekisa khase le liindasteri tsa metallurgical, 'me karolo ea bona liindastering tsa theknoloji e phahameng e ntse e eketseha. Ka hona, e tsejoa e le "vithamine" le "tšepe e ncha ea morao-rao" ea indasteri ea kajeno.

Lilemong tsa morao tjena, tšepe ea sehlopha sa platinum e 'nile ea sebelisoa ka ho eketsehileng liindastering tse kang ho hloekisa mosi oa likoloi le lithuthuthu, lisele tsa mafura, liindasteri tsa elektroniki le tsa motlakase, thepa ea meno le mabenyane. Lekholong la bo21 la lilemo le phephetsang, nts'etsopele ea lisebelisoa tsa tšepe tsa sehlopha sa platinum ka kotloloho e thibela lebelo la nts'etsopele ea masimo ana a theknoloji e phahameng, hape e ama ka ho toba boemo ba machaba moruong oa lefatše.

Mohlala, lipatlisiso mabapi le boits'oaro ba electrocatalytic oxidation ea limolek'hule tse nyane tse kang methanol, formaldehyde, le formic acid, tse ka sebelisoang e le lisele tsa mafura ke li-catalyst tsa nano platinum li na le bohlokoa ba lipatlisiso tsa mantlha tsa theory le tebello e pharaletseng ea ts'ebeliso. Liphuputso li bontšitse hore li-catalyst tse ka sehloohong tse nang le ts'ebetso e itseng ea electrocatalytic oxidation bakeng sa limolek'hule tse nyenyane tsa organic ke litšepe tse ntle tsa sehlopha sa platinum.

Hongwu Nano e khethehile tlhahisong ea thepa ea tšepe ea bohlokoa ea nano ka lilemo tse 15, ho kenyelletsa empa e sa felle feela ho nano platinum, iridium, ruthenium, rhodium, silevera, palladium, khauta. Hangata e fanoa ka foromo ea phofo, ho hasana ho ka boela ha etsoa, ​​​​'me boholo ba likaroloana bo ka fetoloa ho ea ka litlhoko tse itseng.
