Nano Tungsten Trioxide Powder Tungsten(VI) Oxide WO3 Nanoparticle kwa chothandizira

Mafotokozedwe Akatundu

Kufotokozera kwaWO3 Nanoparticle:

Chigawo kukula: 50nm

Chiyero: 99.9%

Mtundu: yellow, blue, purple

Mawonekedwe a WO3 Nanopowder:

1. Kuwala kowoneka kopitilira 70%.

2. Pafupi ndi infrared blocking rate kuposa 90%.

3. UV-kutsekereza mlingo pamwamba 90%.

Kugwiritsa ntchito Nano Tungsten Trioxide Powder:

WO3 nanoparticles ufa ungagwiritsidwe ntchito ngati chothandizira.

Kafukufuku wasonyeza kuti kugwiritsa ntchito 30% H2O2 monga gwero la okosijeni ndi kugwiritsa ntchito tungsten trioxide yokha monga chothandizira kuti cyclohexene ikhale ndi makutidwe ndi okosijeni mu adipic acid imatha kupeza zokolola zambiri ndi chiyero.Pamene kuchuluka kwa tungsten trioxide ndi 5.0 mmol ndi molar chiŵerengero cha WO3: cyclohexene:H2O2 ndi 1:40:176, zimene zimachitika reflux kutentha kwa maola 6, ndi kulekana zokolola za asidi adipic ndi 75.4%.Kuyera ndi 99.8%.Chothandizira cha tungsten trioxide chimagwiritsidwa ntchito mobwerezabwereza ka 4, ndipo zokolola zolekanitsa za adipic acid zimatha kufikira kuposa 70%.Kuphatikiza kusanthula kwa FTIR ndi XRD kunatsimikizira kukhazikika kwadongosolo komanso kukhazikikanso kwa chothandizira panthawi ya okosijeni ya cyclohexene yopangidwa ndi tungsten trioxide.

Poyerekeza ndi chothandizira Pt / CNTs popanda WO3 kusinthidwa, ndi Pt / WO3-CNTs gulu chothandizira osati limasonyeza wachibale lalikulu electrochemical yogwira pamwamba m'dera, mkulu chothandizira ntchito kwa methanol elekitirojeni makutidwe ndi okosijeni, komanso amaonetsa kwambiri bata ndi zikuoneka antiposion kulolerana kwa mitundu yosakwanira ya okosijeni panthawi ya okosijeni ya methanol.
