Aikace-aikacen Nano Tungsten Trioxide Foda:

WO3 nanoparticles foda za a iya amfani dashi azaman mai kara kuzari.

Nazarin ya nuna cewa yin amfani da 30% H2O2 a matsayin tushen oxygen da kuma yin amfani da tungsten trioxide kadai a matsayin mai kara kuzari don ƙaddamar da oxidation na cyclohexene a cikin adipic acid zai iya samun yawan amfanin ƙasa da tsabta.Lokacin da adadin tungsten trioxide ne 5.0 mmol da molar rabo na WO3: cyclohexene: H2O2 ne 1:40:176, da dauki da za'ayi a reflux zafin jiki na 6 hours, da kuma rabuwa yawan amfanin ƙasa na adipic acid ne 75.4%.Tsaftace 99.8%.Tungsten trioxide mai kara kuzari ana maimaita amfani da shi sau 4, kuma yawan adadin adipic acid har yanzu yana iya kaiwa sama da 70%.Haɗuwa da bincike na FTIR da XRD ya tabbatar da kwanciyar hankali na tsari da sake amfani da mai haɓakawa yayin da iskar oxygenation na cyclohexene catalyzed ta hanyar tungsten trioxide.

Idan aka kwatanta da Pt / CNTs mai kara kuzari ba tare da WO3 gyara ba, da Pt / WO3-CNTs composite mai kara kuzari ba kawai nuna dangi manyan electrochemical aiki surface area, high kara kuzari aiki ga methanol electro-hadawan abu da iskar shaka, amma kuma yana nuna babban kwanciyar hankali tare da bayyanannen antiposion haƙuri ga nau'in nau'in oxidized da ba a cika ba a lokacin iskar oxygenation na methanol.
