Chii chinonzi metal catalyst inokosha?

Yakakosha simbi inokonzeresa, sekureva kunoita zita, shandisa simbi dzinokosha sechinhu chinoshanda uye monolithic ceramics senge alumina serutsigiro. Iwo ma catalysts akagadzirwa kuti achinje mwero wemakemikari reactions pasina kutora chikamu mukuita pachako.

Anokosha metal catalyst isimbi yakakosha inogona kushandura chiyero chemakemikari reaction pasina kutora chikamu mune zvekupedzisira zvigadzirwa. Anenge ese masimbi anokosha anogona kushandiswa sezvinokonzeresa, asi platinum, palladium, rhodium, sirivheri, uye ruthenium ndiyo inowanzoshandiswa, ine platinum nerhodium ndiyo inonyanya kushandiswa. D-electron orbitals dzavo hadzina kunyatsozadzwa, zvichiita kuti nzvimbo dzadzo dziwane kuita adsorbing reactants. Simba rine mwero reiyi orbitals rinogonesa kuumbwa kwepakati "active compounds," zvichiita kuti pave nepamusoro pekuita basa. Pamusoro pazvo, vane zvinhu zvakanakisa zvakakwana zvakaita seyepamusoro-kuramba tembiricha, oxidation resistance, uye corrosion resistance, zvichiita kuti zvive zvinhu zvinonyanya kukosha.
