Izinto ze-Tellurium dioxide, ngokukodwa i-nano-level ephezulu yokucocekaI-Tellurium oxide, ziye zatsala umdla obanzi kwishishini. Ngoko ke ziziphi iimpawu ze-nano Tellurium Oxide, kwaye yiyiphi indlela yokulungiselela ekhethekileyo? Iqela le-R & D leUrbanMines Tech Co., Ltd.lishwankathele eli nqaku kwireferensi yoshishino.
Kwinkalo yesayensi yezinto zangoku, i-tellurium dioxide, njengeyona nto ibalaseleyo ye-acousto-optic, ineempawu zesalathisi esiphezulu se-refractive, inguqu enkulu ye-Raman yokuchithwa kwenguqu, i-optics efanelekileyo engabonakaliyo, i-conductivity elungileyo yombane, iipropati ezibalaseleyo ze-acoustoelectric, ukuhanjiswa okuphezulu kwangaphakathi kwe-ultraviolet kunye ukukhanya okubonakalayo, njl.njl. I-Tellurium dioxide isetyenziswa ngokubanzi kwi-optical amplifiers, acousto-optic deflectors, filters, optical conversion...
I-Nanomaterials ineempawu zendawo enkulu yendawo ethile kunye nobukhulu be-particle encinci, enokuyenza ivelise iziphumo eziphezulu, iziphumo ze-quantum kunye nemiphumo yobukhulu. Ngoko ke, uphando olunzulu kwi-tellurium dioxide nanomaterials luyimfuneko kakhulu.
I-Nanomaterials ineempawu zendawo enkulu yendawo ethile kunye nobukhulu be-particle encinci, enokuyenza ivelise iziphumo eziphezulu, iziphumo ze-quantum kunye nemiphumo yobukhulu. Ngoko ke, uphando olunzulu kwi-tellurium dioxide nanomaterials luyimfuneko kakhulu. Okwangoku, iindlela zokulungiselelai-tellurium dioxideI-nanomaterials ihlulwe ngokukodwa kwindlela yokunyuka kwe-thermal kunye ne-sol method. Indlela ye-thermal evaporation yinkqubo yokukhupha ngokuthe ngqo i-elemental tellurium powder eqinile phantsi kweemeko eziphezulu zokushisa ukufumana i-oxide entsha. Ukungalungi kukuba impendulo ifuna ubushushu obuphezulu, izixhobo ziyabiza, kunye nomphunga oyityhefu uveliswa. Uninzi lwe-tellurium dioxide nanomaterials luye lwalungiswa ngokuphuma komphunga. Amasuntswana e-Te elemental akhutshwa ngumphunga ngokusebenzisa i-microwave plasma flame ukulungisa i-spherical tellurium dioxide nanoparticles ene-particle size distribution of 100-25nm. Park et al. I-evaporated Te elemental powder kwityhubhu yequartz engatywinwanga kwi-500 ° C, iguqule ifilimu ye-Ag kumphezulu we-nanorods ye-SiO2, yalungisa i-Ag functionalized tellurium dioxide nanorods kunye nobubanzi be-50-100nm, kwaye isetyenziswe ukuqaphela ukuxinwa kwegesi ye-ethanol. . Indlela ye-sol isebenzisa ipropati ye-tellurium precursors (ngokuqhelekileyo i-tellurite kunye ne-tellurium isopropoxide) ukuba ibe lula i-hydrolyzed. Inkqubo ye-sol ezinzileyo ecacileyo yenziwa emva kokongeza i-asidi catalyst phantsi kweemeko zesigaba solwelo. Emva kokucoca kunye nokumisa, i-tellurium dioxide nano-solid powder ifunyenwe. Indlela ilula ukuyisebenzisa, ihambelana nokusingqongileyo, kwaye impendulo ayifuni ukushisa okuphezulu. Sebenzisa iimpawu ze-asidi ezibuthathaka ze-acetic acid kunye ne-gallic acid ukuze i-catalyze kunye ne-hydrolyze i-Na2TeO3 ukulungiselela i-tellurium dioxide nanoparticle sol, kwaye ufumane i-tellurium dioxide nanoparticles kwiifom ze-crystal ezahlukeneyo, kunye nobukhulu be-particle ukusuka kwi-200-300nm.
