No ke aha e hiki ai ke nanohao nickel cobalt alloyʻāpanae hoʻohana nui ʻia ma ke kahua o nā catalysts?

ʻO ka hana kūikawā a me ka hoʻohui ʻana o ka hao nickel cobalt alloy nano material e hāʻawi iā ia me ka hana catalytic maikaʻi loa a me ke koho, e ʻae iā ia e hōʻike i ka hana maikaʻi loa i nā ʻano hopena kemika.

Aia nā kahua catalystʻO ka hao nickel cobalt alloy nano FeNiConā ʻāpana i hoʻohana mau ʻia?

1. ʻO ka hoʻohaʻahaʻa o ka oxygen (ORR) catalyst: ʻO ka hopena hoʻohaʻahaʻa o ka Oxygen he mea nui ia i nā mea hoʻololi ikehu e like me nā pahu wahie a me nā pihi metala-ea. Hiki i ka nano FeNiCo ternary alloy catalyst ke hoʻoikaika maikaʻi i ka hopena hoʻemi o ka oxygen a hoʻomaikaʻi i ka pono a me ka paʻa o ka hana o ka pā.

2. CO2 hoʻololi hoʻololi: hao nickel cobalt alloy nanopowder hiki ke hoʻohana ʻia ma ke ʻano he catalytic converter no CO2, e hoʻololi ana i ka CO2 i loko o nā kinikona waiwai nui e like me ka formic acid, methanol a me ka acetic acid. Kōkua kēia i ka hōʻemi ʻana i ka hoʻokuʻu ʻia ʻana o ke kinoea ʻōmaʻomaʻo a hoʻokō i ka hoʻohana waiwai o CO2.

3. ʻO ka hoʻomaʻamaʻa wai ʻino: hiki ke hoʻohana ʻia ka hao nickel cobalt alloy nanoparticle e catalytically oxidize pollutants organik i ka wai ʻino. Ma ka catalyzing oxidation reactions, hiki iā lākou ke hoʻololi i nā mea haumia organik i nā huahana ʻino ʻole, e hāpai ana i ka mālama ʻana i ka wai ʻino a me ka pale ʻana i ke kaiapuni.

4. Hydrogenation reaction catalyst: hao nickel cobalt alloy nano pauka hōʻike maikaʻi catalytic hana a me ka selectivity i hydrogenation pane.

5. Organic synthesis catalyst: FeNiCo alloy nano material he ākea ka hoʻohana ʻana ma ke kahua o ka organik synthesis. Hiki iā lākou ke hoʻohana no ka hoʻoulu ʻana i nā ʻano like ʻole o ka synthesis kūlohelohe e like me ka hydrogenation, ka hoʻohui ʻana, ka carbonylation reactions a me ka alkylation reactions, me ka hāʻawi ʻana i nā catalysts maikaʻi, koho a pili i ke kaiapuni.

He aha nā mea e pili ana i ka hana catalytic o ka hao nickel cobalt alloy nano particle?

Hoʻopili ʻia ka hana catalytic o nano ternary alloy FeNiCo e nā mea e like me ka nui o ka palaoa, ka mana morphology, a me ka hoʻololi ʻana i ka ʻili. Ma o ka haku mele ʻana kūpono, nā ʻano hana hoʻomākaukau catalyst a me ka ʻenehana hoʻololi ʻana i ka ʻili, hiki ke hoʻonui hou ʻia ka hana a me ka paʻa o nā nano hao-nickel-cobalt catalysts a hiki ke hoʻonui ʻia kona hiki ke hoʻohana i ke kahua o nā catalysts.
