Nano Tungsten Trioxide Powder Tungsten(VI) Oxide WO3 Nanoparticle for catalyst

Ingcaciso yeMveliso

Inkcazo yeWO3 Nanoparticle:

Ubungakanani besuntswana: 50nm

Ubunyulu: 99.9%

Umbala: tyheli, bhlowu, mfusa

Iimpawu zeWO3 Nanopowder:

1. Ukuhanjiswa kokukhanya okubonakalayo okukhulu kune-70%.

2. Isantya sokuvala i-infrared kufuphi ne-90%.

3. Izinga lokuvalwa kwe-UV ngaphezu kwe-90%.

Ukusetyenziswa kweNano Tungsten Trioxide Powder:

I-WO3 nanoparticles powder ingasetyenziswa njenge-catalyst.

Uphononongo lubonise ukuba ukusebenzisa i-30% ye-H2O2 njengomthombo we-oksijeni kunye nokusebenzisa i-tungsten trioxide yodwa njenge-catalyst ukuze i-oxidation ye-cyclohexene ibe yi-adipic acid inokufikelela kwisivuno esiphezulu kunye nokucoceka.Xa isixa se-tungsten trioxide yi-5.0 mmol kunye ne-molar ratio ye-WO3: i-cyclohexene: i-H2O2 yi-1: 40: 176, ukusabela kuqhutyelwa kwiqondo lokushisa kwe-reflux kwiiyure ze-6, kwaye isivuno sokuhlukana kwe-adipic acid yi-75.4%.Ubunyulu bungama-99.8%.I-tungsten trioxide catalyst isetyenziswe ngokuphindaphindiweyo ngamaxesha angama-4, kwaye isivuno sokwahlula i-adipic acid sisenokufikelela ngaphezu kwe-70%.Ukudibanisa i-FTIR kunye nohlalutyo lwe-XRD lubonakalise ukuzinza kunye nokusebenziseka kwakhona kwe-catalyst ngexesha lokuphendula kwe-oxidation ye-cyclohexene catalyzed yi-tungsten trioxide.

Xa kuthelekiswa ne-Pt / CNTs catalyst ngaphandle kokuguqulwa kwe-WO3, i-Pt / WO3-CNTs i-catalyst edibeneyo ayibonisi nje indawo enkulu ye-electrochemical esebenzayo, umsebenzi ophezulu we-catalyst ngokubhekiselele kwi-methanol electro-oxidation, kodwa ibonisa uzinzo oluphezulu kakhulu kunye nokunyamezela okubonakalayo kwi-antiposion. iintlobo ze-oxidized ezingaphelelanga ngexesha le-methanol oxidation.
