cas 10139-58-9 brown solution rhodium nitrate
Fekitari yakananga simbi yemukati 18.5% cas 32005-36-0 dema yepepuru crystal bis (dibenzylideneacetone) palladium
Nhanganyaya
Akakosha simbi catalysts simbi dzakanaka dzinoshandiswa zvakanyanya muindasitiri yemakemikari nekuda kwekugona kwavo kukurumidzira kuita kwemakemikari. Ndarama, palladium, platinum, rhodium, uye sirivheri mimwe yemienzaniso yesimbi dzinokosha. Yakakosha simbi inokonzeresa ndeaya anosanganisira akaparadzirwa zvakanyanya nano-chiyero chesimbi yakakosha masitadhi anotsigirwa panzvimbo yakakwirira senge kabhoni, silica, uye alumina. Aya macatalyst ane akati wandei maapplication mumaindasitiri akasiyana siyana. Imwe neimwe yakakosha simbi catalyst ine yakasarudzika maitiro. Aya ma catalyst anonyanya kushandiswa kune organic synthesis reactions. Zvinhu zvakadai sekukura kuri kuda kubva kumagumo-ekushandisa zvikamu, zvinonetsa kwezvakatipoteredza uye zvazvinoreva zviri pamutemo zviri kufambisa kukura kwemusika.
Zvivakwa zvesimbi yakakosha inokonzeresa
1.Kushanda kwepamusoro uye kusarudzwa kwesimbi dzinokosha mu catalysis
Yakakosha simbi inokonzeresa inosanganisira yakaparadzirwa zvakanyanya nano-chiyero chesimbi yakakosha zvimedu pazvitsigiro zvine nzvimbo yakakwirira senge kabhoni, silica, uye alumina. Iyo nano scale metal particles inoshambadza nyore haidrojeni neokisijeni mumhepo. Iyo haidhirojeni kana okisijeni inoshanda zvakanyanya nekuda kweiyo dissociative adsorption kuburikidza ne d-electron yekunze kwegoko remaatomu esimbi anokosha.
2.Kugadzikana
Simbi dzakakosha dzakagadzikana. Havagadziri nyore maokisisi neoxidation. Maokisi esimbi anokosha, kune rumwe rutivi, haana kugadzikana. Simbi dzakakosha hadzinyungudike nyore muacid kana alkaline solution. Nekuda kwekugadzikana kwakanyanya kwemafuta, yakakosha simbi inokonzeresa yakashandiswa semotokari inopedza gasi rekuchenesa catalysts.
