Izixhobo zeTellurium dioxide, ingakumbi i-nano-level ephezulu yokucocekaI-Tellurium Oxide, ziye zatsala ingqalelo ebanzi kakhulu kushishino. Ngoko ke zithini iimpawu ze-nano Tellurium Oxide, kwaye yeyiphi indlela ethile yokulungiselela? Iqela le-R & D leI-UrbanMines Tech Co., Ltd.ushwankathele eli nqaku ukuze abhekisele kushishino.
Kwintsimi yesayensi yezinto zanamhlanje, i-tellurium dioxide, njengesixhobo esibalaseleyo se-acousto-optic, ineempawu ze-refractive index ephezulu, i-Raman enkulu yokusasaza, i-nonlinear optics elungileyo, i-electrical conductivity elungileyo, iipropati ze-acoustoelectric ezintle, i-ultraviolet ephezulu kunye nokukhanya okubonakalayo, njl. I-Tellurium dioxide isetyenziswa kakhulu kwi-optical amplifiers, i-acousto-optic deflectors, izihluzi, ukuguqulwa kwe-optical...
Izinto ezisetyenziswa kwi-nanomaterials zineempawu zommandla omkhulu womphezulu kunye nobukhulu obuncinci be-particle, nto leyo enokwenza ukuba ivelise iziphumo zomphezulu, iziphumo ze-quantum kunye neziphumo zobukhulu. Ke ngoko, uphando olunzulu malunga nezinto ezisetyenziswa kwi-tellurium dioxide nanomaterials luyimfuneko kakhulu.
Izinto ezisetyenziswa kwi-nanomaterials zineempawu zommandla omkhulu womphezulu kunye nobukhulu obuncinci be-particle, nto leyo enokwenza ukuba ivelise iziphumo zomphezulu, iziphumo ze-quantum kunye neziphumo zobukhulu. Ke ngoko, uphando olunzulu malunga nezinto ezisetyenziswa kwi-tellurium dioxide nanomaterials luyimfuneko kakhulu. Okwangoku, iindlela zokulungiselelai-tellurium dioxideIzinto ze-nanomaterials zahlulwe ngokubanzi ngendlela yokufuma ngobushushu kunye nendlela ye-sol. Indlela yokufuma ngobushushu yinkqubo yokufunxa ngokuthe ngqo i-elemental tellurium solid powder phantsi kweemeko zobushushu obuphezulu ukuze kufunyanwe i-oxide entsha. Iingxaki kukuba impendulo ifuna ubushushu obuphezulu, izixhobo zibiza kakhulu, kwaye kuveliswa umphunga onobuthi. Izinto ezininzi ze-tellurium dioxide nanomaterials zilungiselelwe ngokufuma. Ii-Te elemental particles ziyafunxa ngokusebenzisa i-air microwave plasma flame ukulungiselela ii-spherical tellurium dioxide nanoparticles ezinokusasazwa kobukhulu be-particle obuyi-100-25nm. UPark et al. baphuhlisa i-Te elemental powder kwityhubhu ye-quartz engavaliweyo kwi-500°C, batshintsha ifilimu ye-Ag kumphezulu wee-nanorods ze-SiO2, balungisa ii-nanorods ze-tellurium dioxide ezisebenza nge-Ag ezinobubanzi obuyi-50-100nm, kwaye bazisebenzise ukubona uxinzelelo lwegesi ye-ethanol. Indlela ye-sol isebenzisa ipropathi yee-tellurium precursors (ngesiqhelo i-tellurite kunye ne-tellurium isopropoxide) ukuze zifunxeke ngokulula. Inkqubo yesol ecacileyo ezinzileyo yenziwa emva kokongeza i-acid catalyst phantsi kweemeko zesigaba solwelo. Emva kokuhluzwa nokomiswa, kufunyanwa i-tellurium dioxide nano-solid powder. Le ndlela ilula ukuyisebenzisa, inobuhlobo nokusingqongileyo, kwaye impendulo ayifuni ubushushu obuphezulu. Sebenzisa iipropati ze-acid ezibuthathaka ze-acetic acid kunye ne-gallic acid ukuze u-catalyze kwaye u-hydrolyze i-Na2TeO3 ukulungiselela i-tellurium dioxide nanoparticle sol, kwaye ufumane i-tellurium dioxide nanoparticles kwiifom ezahlukeneyo zekristale, ezinobukhulu bee-particle obuqala kwi-200-300nm.
