ʻO ka nui o ka metala cas 12135-22-7 75.78% palladium(ii) hydroxide
Nā Hoʻolauna
ʻO nā mea hoʻoulu metala makamae he mau metala hanohano i hoʻohana nui ʻia i ka ʻoihana kemika ma muli o ko lākou hiki ke hoʻolalelale i ke kaʻina hana kemika. ʻO ke gula, palladium, platinum, rhodium, a me ke kālā kekahi o nā hiʻohiʻona o nā metala makamae. ʻO nā mea hoʻoulu metala makamae nā mea i loaʻa nā ʻāpana metala makamae nano-scale i hoʻopuehu nui ʻia i kākoʻo ʻia ma kahi ʻili kiʻekiʻe e like me ke kalapona, silica, a me ka alumina. He nui nā noi o kēia mau mea hoʻoulu i nā ʻoihana like ʻole. Loaʻa i kēlā me kēia mea hoʻoulu metala makamae nā ʻano kūikawā. Hoʻohana nui ʻia kēia mau mea hoʻoulu no nā hopena synthesis organik. ʻO nā mea e like me ka ulu ʻana o ke koi mai nā ʻāpana hoʻohana hope loa, nā hopohopo kaiapuni a me ko lākou hopena kānāwai e hoʻokele nei i ka ulu ʻana o ka mākeke.
Nā waiwai o nā mea hoʻouluulu metala makamae
1. Hana kiʻekiʻe a me ke koho ʻana o nā metala makamae i ka catalysis
ʻO nā mea hoʻoulu metala makamae he mau ʻāpana metala makamae nano-scale i hoʻopuehu nui ʻia ma nā kākoʻo me ka 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 hana nui ka hydrogen a i ʻole ka oxygen ma muli o kāna adsorption dissociative ma o ka d-electron o waho o ka pūpū o nā ʻātoma metala makamae.
2. Paʻa
He paʻa nā metala makamae. ʻAʻole lākou e hana maʻalahi i nā oxides ma o ka oxidation. Ma ka ʻaoʻao ʻē aʻe, ʻaʻole paʻa loa nā oxides o nā metala makamae. ʻAʻole maʻalahi ka hoʻoheheʻe ʻana o nā metala makamae i loko o ka hopena waikawa a alkaline paha. Ma muli o ke kūpaʻa wela kiʻekiʻe, ua hoʻohana ʻia ka mea hoʻonui metala makamae ma ke ʻano he mea hoʻonui hoʻomaʻemaʻe kinoea hoʻopau kaʻa.
