Kugadzirira kwepamusoro-chiitwa chinotsigirwa nano-goridhe catalysts inonyanya kufunga zvinhu zviviri, imwe kugadzirira kwe nano goridhe, iyo inovimbisa yakakwira catalytic chiitiko nehukuru hudiki, uye imwe isarudzo yekutakura, iyo inofanirwa kunge iine yakakura yakati wandei nzvimbo. nzvimbo uye kuita kwakanaka.kunyorova kwepamusoro uye kupindirana kwakasimba neakatsigirwa goridhe nanoparticles uye akapararira zvakanyanya pamusoro pemutakuri.

Kufurira kwemutakuri pane inokonzeresa chiitiko cheAu nanoparticles inonyanya kuratidzwa munzvimbo chaiyo yepasi, kunyorova kwemutakuri wacho uye chiyero chekudyidzana pakati pemutakuri negoridhe nanopowders.Mutakuri ane SSA hombe ndiyo inodiwa yekupararira kwepamusoro kwezvidimbu zvegoridhe.Kunyorova kwemutakuri kunoona kana iyo catalyst yegoridhe ichaungana kuita zvidimbu zvihombe zvegoridhe panguva yekuverengera, nekudaro ichideredza chiitiko chayo chekugadzirisa.Uye zvakare, iyo simba rekudyidzana pakati pemutakuri neAu nanopowders zvakare chinhu chakakosha chinokanganisa chiitiko checatalytic.Kusimba kwesimba rekudyidzana pakati pezvimedu zvegoridhe nemutakuri, ndiko kuwedzera kwekuita kwekuita kwegold catalyst.

Parizvino, mazhinji eanoshanda zvakanyanya nano Au catalysts anotsigirwa.Kuvapo kwerutsigiro hakusi kungogadzirisa kugadzikana kwemhando dzegoridhe dzinoshanda, asiwo dzinoita basa rinokosha mukusimudzira basa rekuita kwese catalyst nekuda kwekubatana pakati pekutsigirwa uye nanoparticles yegoridhe.

Huwandu hukuru hwemhedzisiro yetsvagiridzo inoratidza kuti nano-goridhe inokwanisa kukonzeresa kwakasiyana siyana kwemakemikari kuita, uye inotarisirwa kutsiva zvizere kana zvishoma zvakatsiva zviripo zvakakosha simbi catalysts sePd nePt muminda yeakanaka kemikari synthesis uye kurapwa kwezvakatipoteredza. , kuratidza tarisiro yakakura yekushandisa:

1. Sarudza Oxidation

Kusarudza oxidation yedoro uye aldehydes, epoxidation yeolefins, yakasarudzwa oxidation yemahydrocarboni, synthesis yeH2O2.

2. Hydrogenation reaction

Hydrogenation ye olefins;kusarudza hydrogenation yeunsaturated aldehydes uye ketone;Sarudzo yehydrogenation yenitrobenzene makomisheni, iyo data inoratidza kuti iyo Au/SiO2 catalyst ine nano-goridhe kurodha ye1% inogona kuona iyo inoshanda catalysis yeyakakwirira-kuchena halogenated anonhuwirira amines hydrogenation synthesis inopa mukana mutsva kugadzirisa dambudziko re dehalogenation necatalytic. hydrogenolysis mune yazvino maindasitiri maitiro.

Nano Au catalysts anoshandiswa zvakanyanya mu biosensors, yakakwirira-inoshanda catalysts, uye goridhe ine yakanaka kugadzikana kwemakemikari.Ndiyo yakanyanya kugadzikana pakati peboka VIII zvinhu, asi goridhe nanoparticles inoratidza yakanakisa catalytic chiitiko nekuda kwediki saizi mhedzisiro, nonlinear optics, nezvimwe.

Mukugadzirisa maitiro akafanana, nano goridhe catalyst ine yakaderera kuita tembiricha uye yakakwirira kusarudza kupfuura general metal catalysts, uye yakaderera-tembiricha inokonzeresa yakakwira.Iyo inokonzeresa chiitiko pakuita tembiricha ye200 ° C yakakwira zvakanyanya kupfuura iyo yekutengesa CuO-ZnO-Al2O3 catalyst.

1. CO oxidation reaction

2. Kudzika kwekushisa kwemvura gasi kuchinja maitiro

3. Liquid-phase hydrogenation reaction

4. Liquid-phase oxidation reactions, kusanganisira ethylene glycol oxidation kuti ibudise oxalic acid, uye inosarudza oxidation yeglucose.
