Zvichienderana nemesous uye macropus Mukuwedzera, chimiro cheNanupopus chave nzvimbo inopisa mukugadzirwa kwegasi yekunzwa zvinhu nekuda kweiyo hombe ssa ssa, gasi rakapfuma ssals uye misa misa kuendesa nzira.

2. Gasi yekunzwa zvinhu zvinoshandiswa nano Iron oxide (fe2o3)

Iron Oxide (Fe2o3)ine mafomu maviri ekristaro: Alfa naGamma, ese ari maviri anogona kushandiswa segesi yekunzwa gasi zvinhu, asi gasi yekunzwa zvivakwa zvadzo zvine misiyano mikuru. α-fe2o3 ndezve corungundy chimiro, ayo ane zvivakwa zvemuviri akagadzikana. Gasi rayo rekunzwa mechanism inodzorwa, uye kunzwa kwayo kwakaderera. γ-fo2o3 ndezve spinel chimiro uye chishamiso. Gasi rayo rekunzwa mechanism rinonyanya kudzivisa muviri

Iyo yekutsvaga yazvino inotarisa pane inogadzirisa mamiriro eSynthesis kudzora morphology ye fe2o3 nanobeps, monoro3 nanorors, mesoo3 nanomater, et

3. Gasi yekunzwa zvinhu zvinoshandiswa nano zinc oxide (zno)
Zinc oxide (zno)chinhu chakajairika-chinodzorwa gasi-inotsvedza zvinhu. Iyo zno-yakavakirwa gasi sensor ine yakakwira yekushandisa tembiricha uye kusarudzika kusarudzika, zvichiita kuti isanyanya kusarudzika pane sno2 uye fe2o3 nanopods. Naizvozvo, kugadzirira kwechimiro chitsva cheZno Nanomaterials, kugadzirisa shanduko yeNano-Zno kuderedza tembiricha uye kuvandudza kusarudzika ndiko kutarisisa kwekutsvaga kweNano Gno Sknessing zvinhu.

Parizvino, kukura kweimwe crystal nano-zno gasi yekunzwa chinhu chimwe chezviratidziro chekumberi, senge zno imwe crystal n hanrod gasi sensors.

4. Gasi yekunzwa zvinhu zvinoshandiswa nano indium oxide (in2o3)
Indium Oxide (In2o3)iri kubuda n-type semiconductor gasi yekunzwa zvinhu. Kuenzaniswa neSno2, zno, fe2o3, nezvimwe, iyo yakafara band gap, kusadzivirira kushoma uye kushushikana kwechikuru, uye kunzwa kwakanyanya kuCO uye NO2. Porous Nanomaterials inomiririrwa naNano in2o3 ndeimwe yeiyo ichangobva kutsvagisa hotspots. Vaongorori vakasarudzika vakarairwa mesoporous in2o3 zvinhu nenzira ye mesoporous silika template template. Zvigadzirwa zvakawanikwa zvine chimiro chakanaka muhuwandu hwe450-650 ° C, saka vakakodzera kune gasi sensors vane yakakwirira inoshanda tembiricha. Ivo vane hanya neMethane uye vanogona kushandiswa pakutarisa kwakabatana-kwakanangana nekuwoneka.

5. Gasi yekunzwa zvinhu zvinoshandiswa nano tungsten oxide (wo3)
Wo3 NaneopartlesIsland yesimbi yakakomberedza Semiconductor zvinhu izvo zvakadzidzwa zvakanyanya uye zvakanyorerwa kune yayo yakanaka gasi yekunzwa pfuma. Nano Wow3 ine midziyo yakagadzikana senge triclinc, monclinic uye orthorhombic. Vaongorori vakagadzirira Wo3 NaneopArticles neNano-casting nzira uchishandisa mesouprous Sio2 se template. Izvo zvakawanikwa kuti Monclinic Wo3 Naneopartles Weight of 5 nm ine gasi rekunetseka kuita, uye iyo sensor vaviri vakawanikwa neElectrophoretic kuiswa kweVo 4 naneopportles lowination of No2 vane mhinduro yakakwirira.

Iyo Homogeous kugoverwa kweHoxagonal Phase Phase Now1 Nanoclusters yaive yakanyorwa neIion exchange-hydrothermal nzira. Iyo Gasi SentiTivity bvunzo inoratidza kuti Noo nanoclusing gasi sensor ine tembiricha yekudziya, trimethylamine uye yakakodzera kupora nguva, kufumura tarisiro yakanaka yekushandisa yezvinhu.

6. Gasi yekunzwa zvinhu zvinoshandiswa nano titanium dioxide (tio2)
Titanium Dioxide (Tio2)Gasi Sensing Zvigadzirwa zvine zvakanakira zviyero zvakanaka zvekugadzikana uye nyore kugadzirira maitiro, uye zvishoma nezvishoma uve chimwe chinhu chinopisa kune vanotsvaga zvavanotengesa. Parizvino, tsvagurudzo paNano-tio2 gasi sensor inotarisa pane nanantation uye inoshanda yeTIO2 Sensing zvinhu nekushandisa zvinobuda nanotechnology. Semuenzaniso, vaongorori vakagadzira micro-nano-chikero hollow tio2 fibers nekunyora magetsi epectropinning tekinoroji. Kushandisa iyo Yakatemwa Tekinoroji yeTekinoroji, leadrode yakadzokororwa yakaiswa mumurazvo wakatsamwa neTitanixed Tetraisopropoxide kuwanikwa kweSo2.

7. Nolo oxide composites yegesi yekunzwa zvinhu
Iyo gasi ino nyaradza zvivakwa zveNano meturu oxides Podys yekunzwa zvinhu zvinogona kuvandudzwa nekugadzirisa, izvo zvisingori zvisizvo zvemagetsi, asi zvinovandudza kugadzikana uye kusarudza. Kutora zvinhu zvakakosha zvesimbi inzira yakajairika, uye zvinhu zvakadai seAU uye AG zvinowanzoshandiswa seVanonzi Vanoravidza Set Serventi yeNano Zinc oxder poda. Noo oxide composite gasi zvinhu zvinonyanya kusanganisira PD sno2, PT-DEPED firimu, nokudaro achivandudza kunzwa kwayo kunaN2.

Parizvino, Graphene / Nano-Metal oxide makomposites ave hotspot mune gasi sensor zvinhu. Graphene / Sno2 NuanoCominites zvakaitwa zvakanyanyisa kushandiswa seAmmonia Kuwanikwa uye No2 Sensiring Zvigadzirwa.
