1.Applications in Catalysis

Catalysis yezimboni

I-Flakes V₂o₅ isetshenziswa kabanzi njenge-catalyst ekuphendukeni kwamakhemikhali zezimboni ngenxa yokuziphatha kwayo okuqinile kwe-redox kanye nokuqina okuphezulu okushisayo. Idlala indima ebaluleke kakhulu ezinqubweni ezilandelayo:

Ukukhiqizwa kwe-Sulfuric Acid:

I-Flakes V₂o₅ iyi-catalyst ebalulekile kwinqubo yokuxhumana, lapho kusiza khona i-oxidation of Sulfur Dioxide (So₂) eSulfur Trioxide (So₃) ku-Sulfur Trioxide (So₃), Umphakathi Omkhulu ekukhiqizweni kwe-sulfuric acid. Indawo yayo ephezulu yaphezulu iqinisekisa amanani wokuguqulwa afanele nokuqina ngaphansi kwezimo zokusabela okunzima.

Ukukhetha i-oxidation of hydrocarbons:

Embonini ye-petrochemical, ama-flakes v₂o₅ asetshenziselwa ukwenza i-oxidize hydrocarbons anjenge-n-butane ibe yi-anhydride ye-mist anhydride, isandulelo esibalulekile sama-polymers nama-resin. Isakhiwo esibunjiwe sithuthukisa ukukhetha nokuvunyelwa kokusabela.

Ukususwa kwe-ammonia nokuncishiswa kwe-nox:

Ama-Catalysts asuselwa ku-V₂o₅ ahlanganisiwe ekukhetheni kokuncishiswa kwe-catalytic (SCR), okunciphisa ukuphuma kwe-nitrogen oxides (nox) ukuphuma kwamagesi aphelelwa yisikhathi. Ama-flakes morphology aqinisekisa kahle i-ammonia adsorption kanye nokusabela nge-nox, ekhiqiza imvelo i-nitrogen namanzi.

I-chemistry eluhlaza

Ama-Flakes V₂o₅ athole nezinhlelo zokusebenza ku-Green Chemistry, lapho kusiza khona ukusabela okwenzeka emvelweni. Isibonelo, isetshenziswa e-oxidation yotshwala kuma-aldehydes noma ama-ketones ngaphandle kokukhiqiza ama-byproducts ayingozi. Lokhu kuqondanisa nemizamo yomhlaba yokunciphisa imfucumfucu yamakhemikhali futhi yamukele imikhuba esimeme.

2.Izinto ezisetshenziselwa ukugcinwa kwamandla

Amabhethri e-Lithium-ion (ama-libs)

Ama-fladium vagadium pentoxide aqhamuke njengento ethembisayo ye-cathode kumabhethri e-lithium-ion ngenxa yamandla awo aphezulu (~ 294 mah g). Isakhiwo esinqunyelwe sivumela ukufakwa okusebenzayo kwe-Lithium-Ion (Li⁺) nokushintshana kokudonswa kwemali, okuthuthukisa ukusebenza kwebhethri ngokuya nge:

Ubuningi bamandla: Amandla aphezulu ahumusha ngempilo yebhethri ende.
Ukuqina kwe-cycling: ubuqotho bemishini besakhiwo se-flakes behlisa umthamo ngokweqile ngaphezulu kwamacala amaningi khipha imijikelezo.
I-Rate Amandla: Ukufakwa kwe-li⁺ okusheshayo ngokusebenzisa izingqimba kuqinisekisa ukushaja okusheshayo nokukhipha.
Lezi zakhiwo zenza ama-fladium we-fladium alungele ukusetshenziswa ezimotweni zikagesi (evs), i-elekthronikhi ephathekayo, kanye nokugcinwa kwamandla okuvuselelekayo.

Amabhethri e-Sodium-Ion (ama-Sibs) 

Ngesidingo esikhulayo sokugcina amandla angenazindleko futhi esimeme, amabhethri e-sodium-ion athola ukugcwala njengenye yamabhethri e-lithium-ion. I-Flakes vagadium Pentoxide isebenza njengezinto ezinhle kakhulu ze-cathode zama-sibs ngenxa yekhono layo lokuhlalisa ama-sodium ion (NA⁺) ngaphandle kokuwohloka okuhlelekile. Lokhu kwenza kube inketho ebonakalayo yezinhlelo zokugcina amandla ze-grid-scale.

Ama-Supercapacitors

Ama-Supercapacitors adinga izinto zokwenziwa endaweni ephezulu yendawo kanye nezakhiwo ezinhle kakhulu ze-redox ukuze kugcinwe ngamandla. Ama-flokes we-pentoxium pentoxide agcwalisa lezi zidingo, ukunikela:

I-Capacitance ephezulu: Ngenxa yesakhiwo esinqunyelwe kanye nokuqhutshwa okuphezulu.
Isikhathi eside sokuphila: Ngenxa yokuqina okuqinile kwemishini nokuqina kwe-electrochemical.
Lezi zici zenza ama-supercapacitors asuselwa ku-v₂o₅ alungele izinhlelo zokusebenza ezidinga ukulethwa kwamandla okusheshayo, njengezinhlelo zokuvuselela kabusha ezimotweni nasekuhlinzekeni kwamandla okusekelayo.

Izicelo zezemvelo

Ukususwa Okungcolisayo

I-Flas Favadium Pentoxide ifakazele ngempumelelo ekususeni ukungcola kusuka komoya namanzi. Ezinye izinhlelo zokusebenza eziphawuleka zifaka:

Ukuwohloka kwe-PhotoCatalytic kokungcoliswa kwe-organic:
Lapho kuvezwa ukukhanya, i-fladium pentoxium yakha izinhlobo ze-oxygen ezisebenzayo ezibhidliza ukungcoliswa kwezinto eziphilayo emanzi angcolile, njengamadayi, ama-pesticides, kanye nemithi. Indawo yayo ephezulu isheshisa inqubo yokucekelwa phansi, okwenza kube yi-photocatalyst esebenzayo.

Ukuzwakala kwegesi nokuhlanzwa komoya:

I-Nagadium Pentoxideflekes v₂o₅ izwela amagesi anobuthi afana ne-ammonia (NH₃), i-hydrogen sulfide (h₂s), kanye ne-nitrogen oxides (nox). Lokhu kwenza ukuthi ilungele izinzwa zegesi ezisetshenziselwa ukuphepha kwezimboni kanye nokuqapha imvelo. Ngokwengeziwe, kungalimaza i-oxidation yamagesi ayingozi abe ngamafomu amancane anobuthi, afaka isandla ekuhlanzeni komoya.

Ukususwa Kwensimbi Esindayo

Izakhiwo ze-Ion-Exchange ze-Agadium Pentoxide Flakes zikuvumela ukuthi asuse ama-ion esindayo wensimbi, njengokuhola (PB²⁺) ne-Arsenic (as³⁺), kusuka emanzini angcolile. Lolu hlelo lokusebenza lubaluleke ikakhulukazi ezifundeni ezibhekene namanzi ukushoda kwamanzi nokungcola, njengoba kunikeza isixazululo esibiza kakhulu nesisebenzayo sokwelashwa kwamanzi.

4.Izicelo ze-Optoelectronics

Uhlobo lwe-semiconducting lweAma-Flakes V₂o₅Kwenza kube yinto engaba khona yamadivayisi we-opoleelectronic, njenge:

I-Smart Windows: Ngokuguqula izakhiwo zayo zokukhanya ngokuphendula i-stimulal yangaphandle (e.g., Voltage), i-V₂O₅ ingasetshenziswa kumawindows ahlakaniphile asebenza kahle.
PhotoDeteectors: Ama-Flasnas vanadium Pentoxide ekhombisa izithombe ezinhle kakhulu ze-Photorespesponse, okwenza kulungele ukuthola ukukhanya kuma-wavelength ahlukahlukene.
Ukuboniswa kwe-electrocchromic: amandla alo okushintsha umbala ngaphansi kwensimu kagesi kunika amandla ukusetshenziswa kwawo kubuchwepheshe obunamandla bokubonisa amandla.
Lezi zinhlelo zokusebenza zigqamisa ukuguquguquka kwama-fladium we-fladium pentoxide kumadivayisi we-elekthronikhi alandelayo.
