Nano platinum (Pt)no ka mea hoʻoheheʻe ʻekolu ala i ka hoʻomaʻamaʻa ʻana i ka pauka kaʻa

ʻO ka wehewehe pōkole:

ʻO HONGWU NANO mai ka makahiki 2002 i waena o nā mea hana nanoopwders mua loa ma Kina, nā nanopowder metala makamae e like me Pt, Au, Pd, etc. Hāʻawi i ka nui ultrafine ≤20nm, maʻemaʻe kiʻekiʻe 99.95%, me ke kaʻina hana hoʻomohala holomua a me ka maikaʻi kūpaʻa maikaʻi, kumukūʻai hale hana maikaʻi a me ka lawelawe ʻoihana. ʻO kā mākou hale hana i hōʻoia ʻia ʻo ISO.

Nano platinum (Pt)no ka mea hoʻoheheʻe ʻekolu ala i ka hoʻomaʻamaʻa ʻana i ka pauka kaʻa

ʻO ka catalyst ʻekolu ala he catalyst i hoʻohana ʻia i ka mea hoʻololi catalytic ʻekolu o ka pau ʻana o ke kaʻa. Hoʻohana ʻia ia no ka hoʻololi ʻana i ka pauka kaʻa ma mua o ka hoʻokuʻu ʻia ʻana, a e hoʻoneʻe i ka CO, HC, a me NOx i kēlā me kēia, e hōʻemi ana i nā kinoea pōʻino i carbon dioxide (CO2), nitrogen (N2), a me ka mahu wai (H2O) i mea pōʻino i ke kanaka. olakino.
ʻO Pt ka mea hana catalytic mua loa i hoʻohana ʻia i ka hoʻomaʻemaʻe ʻana o nā kaʻa. ʻO kāna haʻawina nui ka hoʻololi ʻana o ka carbon monoxide a me ka hydrocarbons. Loaʻa i ka Pt kahi hiki ke hoʻemi ʻia no ka nitrogen monoxide, akā ke kiʻekiʻe ka NO ka manaʻo a i ʻole ka SO2, ʻaʻole ia e like me ka Rh, a ʻo ka platinum nanoparticles (NPs) e sinter i ka manawa. No ka mea e hoʻonui a hoʻohaʻahaʻa paha ka platinum i nā wela kiʻekiʻe, e hōʻemi ia i ka hana catalytic holoʻokoʻa. Ua hōʻoia ʻia nā haʻawina e hiki ke hoʻololi ʻia nā ʻātoma metala pūʻulu platinum ma waena o nā nanoparticles metala a me ka nui perovskite matrix, a laila e hoʻihoʻi hou i ka hana catalytic.
Loaʻa i nā metala makamae ke koho catalytic maikaʻi loa. Loaʻa nā hopena koʻikoʻi paʻakikī a i ʻole nā ​​hopena synergistic ma waena o nā metala makamae a ma waena o nā metala makamae a me nā mea hoʻolaha. ʻO nā hui metala makamae like ʻole, nā ratios a me nā ʻenehana hoʻouka ʻana he mana nui i ka haku ʻana o ka ʻili, ka ʻili o ka ʻili, ka hana catalytic a me ke kūpaʻa sintering kiʻekiʻe o ka catalyst. Eia kekahi, ʻo nā ʻano like ʻole o ka hoʻohui ʻana i nā mea hoʻolaha e loaʻa kekahi hopena i ka catalyst. Ua hoʻomohala ʻia kahi hanauna hou o nā catalysts ternary Pt-Rh-Pd ma o ka hoʻohana ʻana i ka hoʻohui ikaika ma waena o Pt, Rh a me Pd, kahi i hoʻomaikaʻi nui i ka hana catalyst.
