I-Nano Tungsten Trioxide Powder Tungsten(VI) Oxide WO3 Nanoparticle ye-catalyst

Incazelo Yomkhiqizo

Ukucaciswa kweI-WO3 Nanoparticle:

Usayizi we-particle: 50nm

Ubumsulwa: 99.9%

Umbala: ophuzi, oluhlaza okwesibhakabhaka, onsomi

Izici ze-WO3 Nanopowder:

1. Ukudlulisa ukukhanya okubonakalayo okukhulu kuno-70%.

2. Izinga lokuvinjwa eliseduze kwe-infrared elingaphezu kuka-90%.

3. Izinga lokuvinjwa kwe-UV ngaphezu kwama-90%.

Ukusetshenziswa kwe-Nano Tungsten Trioxide Powder:

I-WO3 nanoparticles powder ingasetshenziswa njenge-catalyst.

Ucwaningo luye lwabonisa ukuthi ukusebenzisa i-30% ye-H2O2 njengomthombo we-oksijeni nokusebenzisa i-tungsten trioxide yodwa njenge-catalyst yokwenza i-oxidation ye-cyclohexene ibe yi-adipic acid ingafinyelela isivuno esiphezulu nobumsulwa.Uma inani le-tungsten trioxide lingu-5.0 mmol kanye ne-molar ratio ye-WO3:cyclohexene:H2O2 ingu-1:40:176, ukusabela kwenziwa ekushiseni kwe-reflux amahora angu-6, kanti isivuno sokuhlukaniswa kwe-adipic acid singama-75.4%.Ubumsulwa bungama-99.8%.I-tungsten trioxide catalyst isetshenziswa ngokuphindaphindiwe izikhathi ezingu-4, futhi isivuno sokuhlukaniswa kwe-adipic acid sisengakwazi ukufinyelela ngaphezu kwama-70%.Ukuhlanganisa i-FTIR kanye nokuhlaziywa kwe-XRD kufakazele ukuzinza kwesakhiwo kanye nokusebenziseka kabusha kwe-catalyst ngesikhathi sokusabela kwe-oxidation ye-cyclohexene ecutshungulwa yi-tungsten trioxide.

Uma kuqhathaniswa ne-Pt/CNTs catalyst ngaphandle kokuguqulwa kwe-WO3, i-Pt/WO3-CNTs eyinhlanganisela ye-catalyst ayibonisi nje indawo enkulu esebenzayo ye-electrochemical, umsebenzi ophezulu we-catalyst maqondana ne-methanol electro-oxidation, kodwa futhi ikhombisa ukuzinza okuphezulu kakhulu ngokubekezelela okubonakalayo kwe-antiposion izinhlobo ze-oxidized ezingaphelele ngesikhathi se-methanol oxidation.
