Cov tshuaj catalysts hlau muaj nqis yog cov hlau zoo uas siv dav hauv kev lag luam tshuaj vim lawv muaj peev xwm ua kom cov txheej txheem tshuaj sai dua. Kub, palladium, platinum, rhodium, thiab nyiaj yog qee qhov piv txwv ntawm cov hlau muaj nqis. Cov tshuaj catalysts hlau muaj nqis yog cov uas muaj cov khoom me me nano-scale uas tau faib tawm ntau heev uas txhawb nqa ntawm thaj chaw siab xws li carbon, silica, thiab alumina. Cov tshuaj catalysts no muaj ntau daim ntawv thov hauv ntau yam lag luam. Txhua cov tshuaj catalyst hlau muaj nqis muaj cov yam ntxwv tshwj xeeb. Cov tshuaj catalysts no feem ntau yog siv rau cov tshuaj tiv thaiv organic synthesis. Cov yam xws li kev thov nce ntxiv los ntawm cov khoom siv kawg, kev txhawj xeeb txog ib puag ncig thiab lawv cov kev cuam tshuam raws li txoj cai yog tsav tsheb kev loj hlob ntawm kev ua lag luam.
Cov khoom ntawm cov hlau muaj nqis catalysts
1. Kev ua haujlwm siab thiab kev xaiv ntawm cov hlau muaj nqis hauv catalysis
Cov tshuaj catalysts hlau muaj cov khoom me me nano-scale uas tawg ua tej daim me me ntawm cov khoom txhawb nqa uas muaj thaj chaw siab xws li carbon, silica, thiab alumina. Cov khoom me me nano-scale yooj yim nqus hydrogen thiab oxygen hauv huab cua. Cov hydrogen lossis oxygen ua haujlwm heev vim nws qhov kev nqus dissociative los ntawm d-electron ntawm lub plhaub ntawm cov hlau muaj nqis.
2. Kev Ruaj Ntseg
Cov hlau muaj nqis ruaj khov. Lawv tsis yooj yim tsim cov oxides los ntawm oxidation. Cov oxides ntawm cov hlau muaj nqis, ntawm qhov tod tes, tsis ruaj khov. Cov hlau muaj nqis tsis yooj yim yaj hauv cov kua qaub lossis alkaline. Vim muaj kev ruaj khov thermal siab, cov catalyst hlau muaj nqis tau siv los ua cov catalysts ntxuav cov pa roj tawm hauv tsheb.
