Li-nanoparticles tsa Biphasic Cerium Oxide: Tšebelisano-'moho ea Kopo e 'Meli
Tsoelo-pele ea morao tjena theknolojing ea nanotechnology e tlisitse mehla e mecha ea thepa e nang le thepa e ikhethang, haholo-holo lefapheng la polokelo ea matla le lisebelisoa tsa elektroniki. Ncha e 'ngoe e ikhethang joalo ke nts'etsopele ea biphasiclikaroloana tse nyenyane tsa cerium oxide, tse hlahileng e le thepa e sebetsang habeli lits'ebetsong tsa dielectric le supercapacitor. Katleho ena, e hlahlobiloeng ke Prakash et al., e senola monyetla o moholo oa hore li-nanoparticles tsa cerium oxide li fetole mahlale a hajoale, li fana ka lintlafatso tse ka ruang molemo haholo lits'ebetsong tsa indasteri le tsa bareki.
Cerium oxide, thepa e feto-fetohang e tsebahalang ka bokgoni ba yona ba ho boloka oksijene le boitshwaro ba redox, e hapile tlhokomelo masimong a fapaneng. Dikaroloana tsa yona tse nyane, ka lebaka la karolelano ya tsona e phahameng ya sebaka le bophahamo, di bontsha thepa e ntlafetseng e leng ya bohlokwa bakeng sa ditshebediso tse tswetseng pele. Phuputso e entsweng ke Prakash le basebetsi mmoho le yena ha e hatise feela ho feto-fetoha ha sebopeho le tshebetso ha dikaroloana tsena tse nyane empa hape le bokgoni ba tsona ba mesebetsi e mmedi bo ka thusang mefuta e mengata ya ditshebediso. Tshebetso ena ya tshebedisano e behacerium oxideLi-nanoparticles li etella pele boqapi bo reretsoeng ho sebetsana le tlhoko e ntseng e eketseha ea litharollo tse sebetsang hantle tsa eneji.
Phuputso ena e hlalosa ka hloko maano a maiketsetso a sebediswang ho hlahisa di-nanoparticles tsa biphasic cerium oxide. Bafuputsi ba sebedisitse mokgwa wa hydrothermal bakeng sa tshebetso ya ho kopanya, e leng se dumellang taolo e nepahetseng hodima boholo ba dikarolwana le sebopeho sa tsona. Ka ho fetola diparamente tse fapaneng tsa ho kopanya, ba fihletse di-nanoparticles tse bontshang dibopeho tsa fluorite le monoclinic. Motswako ona o ikgethang wa mekhahlelo ke wa bohlokwa kaha o ntlafatsa thepa ya elektroniki e hlokahalang bakeng sa tshebetso e ntle ka ho fetisisa ditsamaisong tsa polokelo ya matla.
Mekhoa ea ho hlalosa litšobotsi tse kang X-ray diffraction (XRD) le transmission electron microscopy (TEM) li sebelisitsoe haholo ho sekaseka nanoparticles tse entsoeng. Liphetho tsa XRD li tiisitse boteng ba mekhahlelo ka bobeli ea kristale, ha pono ea TEM e fane ka litšoantšo tse hlakileng tse bontšang ho tšoana ha nanoparticles le taolo ea boholo. Mekhoa ena ha e netefatse feela protocol ea synthesis empa hape e bontša litšobotsi tse tšepisang tsa thepa tse ka lebisang ntlafatsong e kholo ea matla le conductivity.
E 'ngoe ea litšobotsi tse susumetsang tsa biphasic cerium oxide nanoparticles ke thepa ea tsona ea dielectric. Dielectrics li bapala karolo ea bohlokoa lisebelisoa tsa elektroniki, li susumetsa bokhoni ba tsona ba ts'ebetso, ho kenyeletsoa polokelo ea matla le phetisetso ea matšoao. Sebopeho sa biphasic sa cerium oxide se nolofalletsa boleng bo ntlafalitsoeng ba dielectric constant le tahlehelo ea tangent, e leng se etsang hore li tšoanelehe haholo bakeng sa lits'ebetso tse fapaneng ho li-capacitor le likarolo tse ling tsa elektroniki. Ntlafatso ena e bohlokoa bakeng sa lisebelisoa tsa moloko o latelang tse hlokang bokhoni bo phahameng le lintlha tse nyane tsa sebopeho.
Ho feta moo, phuputso ena e hlahlobisisa ditshebediso tsa supercapacitor tsa cerium oxide nanoparticles. Supercapacitors di tsebahala ka bokgoni ba tsona ba ho fana ka matla a phatlohileng kapele, haholoholo ditshebedisong tse hlokang ho tjhaja ka potlako le ho ntsha motlakase ka potlako. Ho kenngwa ha biphasic cerium oxide nanoparticles moralong wa supercapacitor ho bontshitse diphetho tse tshepisang, ho ntlafatsa boleng ba capacitance ha ho ntse ho bolokwa botsitso bo botle ba potoloho. Karolo ena e ba etsa mokhethoa ya matla bakeng sa ditharollo tsa polokelo ya matla dikoloing tsa motlakase le ditsamaisong tsa matla a ntjhafatswang.
Karolo e khahlisang ea lipatlisiso e amana le botsitso ba tikoloho bo amanang le ho sebelisa li-nanoparticles tsa cerium oxide. Ha liindasteri li ntse li hatisa haholoanyane thepa e mosa ho tikoloho, ho kopanngoa le ts'ebeliso ea cerium oxide le hona ho tsamaisana le melao-motheo ea k'hemistri e tala. Ho kenyelletsoa ha thepa e bobebe, e seng chefo ho ka fella ka lihlahisoa tse sireletsehileng le ho fokotsa khatello ea tikoloho eo hangata e amanang le mahlale a setso a capacitor.
Liphihlelo tsa Prakash le ba bang li kenya letsoho haholo lingoliloeng tse seng li ntse li le teng, li fana ka kutloisiso e felletseng ea hore na li-nanoparticles tsa biphasic cerium oxide nanoparticles li sebetsa joang. Ka ho hlakisa mekhoa ea tsona le lits'ebetso tse ka bang teng ka liprothokholo tse thata tsa liteko, lipatlisiso li lokisa motheo bakeng sa lithuto tsa nakong e tlang. Mosebetsi o joalo oa motheo o bohlokoa bakeng sa bafuputsi ba indasteri le baenjiniere ba ikemiselitseng ho ntlafatsa haholoanyane lefapheng la polokelo ea matla le lisebelisoa tsa elektroniki.
Sebakeng se ntseng se fetoha sa theknoloji, bokhoni ba ho iketsetsa thepa ho nanoscale bo fana ka menyetla e meholo ea boqapi. Li-nanoparticles tsa biphasic cerium oxide tse senotsoeng lipatlisisong tsena ke bopaki ba kamoo nanotechnology e ka lebisang katlehong e kholo. Ka lipatlisiso le nts'etsopele e tsoelang pele, re ka bona thepa ena e kopanngoa le lihlahisoa tsa letsatsi le letsatsi, e ntlafatsa ts'ebetso ea tsona le litekanyo tsa ts'ebetso.
