cas 13933-32-9 tetraammine platinum (ii) chloride

ʻO nā metala makamae he mau metala hanohano i hoʻohana nui ʻia i ka ʻoihana kemika ma muli o ko lākou hiki ke wikiwiki i ka hana kemika.ʻO ke gula, ka palladium, ka platinum, ka rhodium, a me ke kālā kekahi o nā laʻana o nā metala makamae.ʻO nā mea hoʻoheheʻe metala makamae nā mea i hoʻopuehu nui ʻia i nā mea metala makamae nano-scale i kākoʻo ʻia ma kahi ʻāpana kiʻekiʻe e like me ke kalapona, silica, a me ka alumina.He nui nā noi o kēia mau catalysts ma nā ʻano ʻoihana like ʻole.Loaʻa i kēlā me kēia catalyst metala makamae nā hiʻohiʻona kūʻokoʻa.Hoʻohana nui ʻia kēia mau catalysts no nā hopena synthesis organik.ʻO nā mea e like me ka ulu ʻana o ka noi mai nā ʻāpana hoʻohana hope, nā hopohopo kaiapuni a me kā lākou mau hopena kānāwai e alakaʻi nei i ka ulu ʻana o ka mākeke.
Nā waiwai o nā mea hoʻoheheʻe metala makamae
1.High hana a me ke koho o na metala makamae ma catalysis
ʻO nā mea hoʻoheheʻe metala makamae he mau ʻāpana metala makamae nano-scale i hoʻopuehu nui ʻia ma nā kākoʻo me kahi ʻili kiʻekiʻe e like me ke kalapona, silica, a me ka alumina.Hoʻopili maʻalahi nā ʻāpana metala nano scale i ka hydrogen a me ka oxygen i ka lewa.He ikaika loa ka hydrogen a i ʻole ka oxygen ma muli o kona hoʻoheheʻe ʻia ʻana ma o ka d-electron o waho o ka pūpū o nā mana metala makamae.
2. Paʻa
Paʻa nā metala makamae.ʻAʻole maʻalahi lākou e hana i nā oxides ma o ka oxidation.ʻO nā oxides o nā metala makamae, ma kekahi ʻaoʻao, ʻaʻole paʻa.ʻAʻole hiki ke hoʻoheheʻe ʻia nā metala makamae i loko o ka ʻakika a i ʻole ka hopena alkaline.Ma muli o ke kūpaʻa wela kiʻekiʻe, ua hoʻohana ʻia ka catalyst metala makamae e like me nā catalysts hoʻomaʻemaʻe kinoea.
