Yog vim li cas nanohlau nickel cobalt alloyparticletau dav siv nyob rau hauv lub tshav pob ntawm catalysts?

Cov qauv tshwj xeeb thiab muaj pes tsawg leeg ntawm cov hlau npib tsib xee cobalt alloy nano cov khoom ua rau nws muaj kev ua haujlwm zoo catalytic thiab kev xaiv, tso cai rau nws ua kom pom kev ua tau zoo hauv ntau yam tshuaj tiv thaiv.

Nyob rau hauv uas catalyst teb yogHlau nickel cobalt alloy nano FeNiCofeem ntau siv?

1. Cov tshuaj tiv thaiv kev txo cov pa oxygen (ORR) catalyst: Cov tshuaj txo cov pa oxygen yog cov tshuaj tiv thaiv tseem ceeb hauv cov khoom siv hluav taws xob hloov pauv xws li roj hlwb thiab cov roj teeb hlau-air. Lub nano FeNiCo ternary alloy catalyst tuaj yeem ua kom cov pa oxygen txo cov tshuaj tiv thaiv thiab txhim kho kev ua haujlwm thiab kev ua haujlwm ruaj khov ntawm lub roj teeb.

2. CO2 hloov dua siab tshiab catalyst: hlau nickel cobalt alloy nanopowder kuj tseem siv tau los ua catalytic converter rau CO2, hloov CO2 rau hauv cov khoom muaj nqis ntxiv xws li formic acid, methanol thiab acetic acid. Qhov no pab txo qis cov pa hluav taws xob hauv tsev cog khoom thiab ua tiav cov peev txheej siv CO2.

3. Kev kho dej khib nyiab catalyst: hlau nickel cobalt alloy nanoparticle tuaj yeem siv rau catalytically oxidize organic pollutants hauv dej khib nyiab. Los ntawm catalyzing cov tshuaj tiv thaiv oxidation, lawv tuaj yeem hloov cov pa phem hauv cov khoom tsis zoo, txhawb kev kho dej khib nyiab thiab kev tiv thaiv ib puag ncig.

4. Hydrogenation cov tshuaj tiv thaiv catalyst: hlau npib tsib xee cobalt alloy nano hmoov qhia tau hais tias zoo catalytic kev ua si thiab selectivity nyob rau hauv hydrogenation cov tshuaj tiv thaiv.

5. Organic synthesis catalyst: FeNiCo alloy nano khoom muaj kev siv dav hauv thaj chaw ntawm cov organic synthesis. Lawv tuaj yeem siv los ua kom muaj ntau yam kev sib xyaw ua ke ntawm cov organic xws li hydrogenation, coupling tshua, cov tshuaj tiv thaiv carbonylation thiab cov tshuaj tiv thaiv alkylation, muab cov txiaj ntsig zoo, xaiv thiab ib puag ncig tus phooj ywg catalysts.

Dab tsi yuav cuam tshuam rau kev ua haujlwm catalytic ntawm hlau nickel cobalt alloy nano particle?

Lub catalytic kev ua tau zoo ntawm nano ternary alloy FeNiCo yog cuam tshuam los ntawm cov yam xws li grain loj, morphology tswj, thiab nto hloov kho. Los ntawm qhov tsim nyog alloy muaj pes tsawg leeg, cov txheej txheem kev npaj catalyst thiab kev hloov kho saum npoo av, kev ua haujlwm thiab kev ruaj ntseg ntawm nano hlau-nickel-cobalt catalysts tuaj yeem txhim kho ntxiv thiab nws daim ntawv thov muaj peev xwm hauv thaj tsam ntawm catalysts tuaj yeem nthuav dav.
