Nano Tungsten Trioxide Powder Tungsten(VI) Oxide WO3 Nanoparticle bakeng sa catalyst

Tlhaloso ea Sehlahisoa

Tlhaloso eaWO3 Nanoparticle:

Boholo ba likarolo: 50nm

Bohloeki: 99.9%

Mmala: o mosehla, o moputsoa, ​​o pherese

Likarolo tsa WO3 Nanopowder:

1. Leseli le bonahalang le fetisa 70%.

2. Sekhahla sa ho thibela haufi le infrared ka holimo ho 90%.

3. Sekhahla sa ho thibela UV ka holimo ho 90%.

Tšebeliso ea Nano Tungsten Trioxide Powder:

WO3 nanoparticles phofo e ka sebelisoa e le sesosa.

Liphuputso li bontšitse hore ho sebelisa 30% H2O2 e le mohloli oa oksijene le ho sebelisa tungsten trioxide feela e le mokhoa oa ho etsa hore oxidation ea cyclohexene e be adipic acid e ka finyella chai e phahameng le bohloeki.Ha palo ea tungsten trioxide e le 5.0 mmol le molar ratio ea WO3: cyclohexene:H2O2 ke 1:40:176, karabelo e etsoa ka mocheso oa reflux ka lihora tse 6, 'me lihlahisoa tsa karohano tsa adipic acid ke 75.4%.Bohloeki ke 99.8%.Tungsten trioxide catalyst e sebelisoa khafetsa ka makhetlo a 4, 'me lihlahisoa tsa karohano tsa adipic acid li ntse li ka fihla ho feta 70%.Ho kopanya tlhahlobo ea FTIR le XRD ho pakile botsitso ba sebopeho le ts'ebetso ea ts'ebetso ea mokelikeli nakong ea karabelo ea oxidation ea cyclohexene e hlahisoang ke tungsten trioxide.

Ha ho bapisoa le Pt / CNTs catalyst ntle le phetoho ea WO3, motsoako oa Pt / WO3-CNTs ha o bontše feela sebaka se seholo sa electrochemical se sebetsang holim'a metsi, ts'ebetso e phahameng ea ts'ebetso e lebisang methanol electro-oxidation, empa hape e bonts'a botsitso bo phahameng haholo ka mamello e hlakileng ea antiposion ho mefuta e sa fellang ea oxidized nakong ea oxidation ea methanol.
