Izinsimbi zeqembu lePlatinum zifaka iplatinum(Pt), i-rhodium(Rh), i-palladium(Pd), i-ruthenium(Ru), i-osmium(Os), ne-iridium(Ir), okungezezinsimbi eziyigugu njengegolide(Au) nesiliva(Ag) . Anamabhondi e-athomu aqine ngokwedlulele, futhi ngaleyo ndlela abe namandla amakhulu okuhlanganisa i-interatomic kanye nokuminyana kwenqwaba okukhulu. Inombolo yokuxhumana ye-athomu yazo zonke izinsimbi zeqembu leplatinamu ngu-6, okunquma izici zazo eziyingqayizivele zomzimba namakhemikhali. Izinsimbi zeqembu lePlatinum zinamaphuzu aphezulu ancibilikayo, ukuhamba kahle kukagesi nokumelana nokugqwala, amandla okushisa aphezulu kanye nokumelana nokukhuphuka kwezinga lokushisa eliphezulu, nokuzinza okuhle kwezinga lokushisa eliphezulu. Lezi zici zibenza zibe izinto ezibalulekile embonini yesimanje kanye nokwakhiwa kwezokuvikela kazwelonke, ezisetshenziswa kabanzi kwezokundiza, i-aerospace, amarokhethi, amandla e-athomu, ubuchwepheshe be-microelectronics, amakhemikhali, ingilazi, ukuhlanzwa kwegesi kanye nezimboni ze-metallurgical, futhi indima yabo ezimbonini zobuchwepheshe obuphezulu iyanda. Ngakho-ke, yaziwa ngokuthi "ivithamini" kanye "nensimbi entsha yesimanje" yemboni yesimanje.

Eminyakeni yamuva nje, izinsimbi zeqembu leplatinamu bezilokhu zisetshenziswa kakhulu ezimbonini ezifana nokuhlanzwa kokukhipha umoya wezimoto nezithuthuthu, amaseli kaphethiloli, izimboni zikagesi nezikagesi, izinto zamazinyo nobucwebe. Ekhulwini lama-21 eliyinselele, ukuthuthukiswa kwezinto zensimbi zeqembu leplatinamu kuvimbela ngokuqondile isivinini sokuthuthukiswa kwalezi zindawo zobuchwepheshe obuphezulu, futhi kuthinta ngokuqondile isikhundla samazwe ngamazwe emnothweni wezwe.

Isibonelo, ucwaningo ngokuziphatha kwe-electrocatalytic oxidation yama-molecule amancane e-organic njenge-methanol, i-formaldehyde, ne-formic acid, engasetshenziswa njengamaseli kaphethiloli yi-nano platinum catalysts inokubili ukubaluleka kocwaningo lwetiyori oluyisisekelo kanye namathemba okusebenza abanzi. Ucwaningo luye lwabonisa ukuthi ama-catalysts amakhulu anomsebenzi othile we-electrocatalytic oxidation wama-molecule amancane ezinto eziphilayo ikakhulukazi izinsimbi ze-platinum zeqembu.

I-Hongwu Nano ikhethekile ekukhiqizeni izinto zensimbi eziyigugu ze-nano eminyakeni engu-15, kuhlanganise kodwa ingagcini nje nge-nano platinum, i-iridium, i-ruthenium, i-rhodium, isiliva, i-palladium, igolide. Kuvame ukuhlinzekwa ngefomu lempushana, ukuhlakazeka kungabuye kube ngokwezifiso, futhi usayizi wezinhlayiyana ungashintshwa ngokuvumelana nezidingo ezithile.
