Nano Tungsten Trioxide Powder Tungsten(VI) Oxide WO3 Nanoparticle no ka mea hoʻoheheʻe

Hōʻike huahana

Hōʻike oWO3 Nanoparticle:

Nui ʻāpana: 50nm

Maʻemaʻe: 99.9%

kala: melemele, uliuli, poni

Nā hiʻohiʻona o WO3 Nanopowder:

1. ʻOi aku ka nui o ka transmittance māmā ma mua o 70%.

2. Near-infrared blocking rate ma luna o 90%.

3. UV-pale ka nui ma luna o 90%.

Ka noi ʻana o Nano Tungsten Trioxide Powder:

Hiki ke hoʻohana ʻia ka pauka WO3 nanoparticles e like me ka catalyst.

Ua hōʻike nā haʻawina i ka hoʻohana ʻana i ka 30% H2O2 ma ke ʻano he kumu oxygen a me ka hoʻohana ʻana i ka tungsten trioxide wale nō ma ke ʻano he catalyst e hoʻoulu i ka oxidation o ka cyclohexene i loko o ka adipic acid hiki ke loaʻa i ka hua kiʻekiʻe a me ka maʻemaʻe. Ke 5.0 mmol ka nui o ka tungsten trioxide a me ka lakio molar o WO3: cyclohexene: H2O2 he 1:40:176, ua lawe ʻia ka hopena ma ka reflux wela no 6 mau hola, a ʻo ka hoʻokaʻawale ʻana o ka waikawa adipic he 75.4%. ʻO ka maʻemaʻe he 99.8%. Hoʻohana pinepine ʻia ka tungsten trioxide catalyst i 4 mau manawa, a hiki i ka hoʻokaʻawale ʻana o ka waikawa adipic hiki ke piʻi ma mua o 70%. ʻO ka hoʻohui ʻana i ka FTIR a me ka nānā ʻana XRD i hōʻoia i ka paʻa a me ka hoʻohana hou ʻana o ka catalyst i ka wā o ka oxidation reaction o cyclohexene catalyzed e tungsten trioxide.

Hoʻohālikelike ʻia me ka catalyst Pt/CNTs me ka hoʻololi ʻole ʻana o WO3, ʻaʻole hōʻike wale ka Pt/WO3-CNTs composite catalyst pili i ka nui o ka ʻili electrochemical ikaika, ka hana catalyst kiʻekiʻe e pili ana i ka methanol electro-oxidation, akā hōʻike pū nō hoʻi i ke kūpaʻa kiʻekiʻe loa me ka hoʻomanawanui antiposion i ka nā ʻano oxidized piha ʻole i ka wā o ka oxidation methanol.
