ʻO nā metala maikaʻiʻole nā ​​metalats i hoʻohana nuiʻia ma kaʻoihana maʻamau i hoʻohanaʻia i loko o kaʻoihana kemika i ko lākou hiki ke wikiwiki i ke kaʻina hana. Gold Gold, Palladium, Platunium, Rhoditium, Rhodium, a me nā kala, aʻo kekahi mau kala,ʻo kekahi o nā hiʻohiʻona o nā metala nui. Precious metal catalysts are those which consist of highly dispersed nano-scale precious metal particles supported on a high surface area such as carbon, silica, and alumina. Ua loaʻa i kēia mau papa hana nā noi i nāʻano hana likeʻole. Loaʻa i kēlā me kēia mea nui keʻano o nā mea i loaʻa i nā hiʻohiʻona. Hoʻohana muaʻia kēia mau catalyts no nāʻano synthes synthes. ʻO nā mea e like me ka uluʻanaʻana i nā koi mai nāʻaoʻao e hoʻohana ai, e pili ana i nā hopohopo kūlohelohe a me ko lākou mau kānāwai kānāwai e holo ana i ka ulu mākeke.
Nā waiwai o nā waiwai waiwai nui
1.ʻO nā hana a me ke kohoʻana o nā metala koʻikoʻi i loko o ka catlysis
ʻO nā mea kūʻai aku i loaʻa i nā catalysts nui o nā mea hao nui e like me nā mea hao nui e like me ke carbulage ʻO nā inoa inoaʻo nano sticard i nā haʻahaʻa adsorb hydrogen a me ka oxygen i ka lewa. ʻO ka hydrogen a iʻole ka oxygen ka ikaika loa ma muli o kāna hoʻolahaʻana e pili ana i ka D-Electron o waho o nā'āpana waiwai nui.

Ke kūpaʻa nei nā metala Precity. ʻAʻole lākou e hana maʻalahi i nā'āpana i ka oxdation. ʻO nā'ōmole o nā metala koʻikoʻi, ma ka lima'ē aʻe,ʻaʻole paʻa. ʻAʻole maʻalahi ka maʻalahi o nā metala i nā metala i ka acid a iʻole nā ​​alkaline result. Ma muli o keʻano kiʻekiʻe o ka getaly internaty, ua hoʻohana nuiʻia ka catalytast bearlyst e like me ke kaʻa kaʻa kaʻa kaʻa kaʻa.
