Kev npaj ntawm cov kev ua si siab txhawb nano-kub catalysts tsuas yog ua kom muaj qhov loj me me, thiab lwm yam yog qhov chaw tshwj xeeb thiab kev ua tau zoo. High wettability thiab muaj kev cuam tshuam nrog kev txhawb nqa kub nanoparticles thiab lawv tau tawg heev rau saum npoo ntawm cov cab kuj.

Tus cab kuj ntawm catalytic kev ua ub no feem ntau yog manampested nyob rau thaj tsam ntawm thaj chaw tshwj xeeb thiab qib ntawm kev sib cuam tshuam ntawm cov cab kuj thiab kub nanopowders. Tus cab kuj nrog ib tug loj ssa yog qhov yuav tsum tau ua ntej rau cov siab dispersion ntawm kub hais. Lub wettability ntawm cov cab kuj txiav txim siab seb puas muaj kub catalitys yuav sib sau ua ke rau hauv cov nyiaj loj no, yog li txo nws cov kev ua si canalytic. Tsis tas li ntawd, kev sib cuam tshuam lub zog ntawm cov cab kuj thiab AU nanopowders kuj tseem yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm catalytic. Cov muaj zog dua kev sib cuam tshuam ntawm cov kub hais thiab cov cab kuj, qhov siab dua cov kev ua ub no ntawm cov kub catalystic.

Tam sim no, feem ntau ntawm cov nquag nano AU catalysts yog txaus siab. Lub hav zoov ntawm kev txhawb nqa tsis yog tsuas yog pab kom ruaj khov ntawm cov khoom siv kub uas muaj kev cuam tshuam nrog kev sib cuam tshuam ntawm kev txhawb nqa thiab kub nanoparticles.

Ib tug ntau ntawm cov txiaj ntsig kev tshawb fawb pom tias nano-kub muaj lub peev xwm los ua kom muaj ntau yam tshuaj lom neeg ua haujlwm xws li kev siv hluav taws xob uas twb muaj lawm, qhia dav kev thov kev cia siab:

1. Kev xaiv oxidation

Xaiv oxidation ntawm cawv thiab aldehydes, epoxidation ntawm Olfins, xaiv oxidation ntawm hydrocarbons, synthesis ntawm H2O2.

2. Hydrogenation cov tshuaj tiv thaiv

Hydrogenation Olfins; xaiv hydrogenation ntawm unsaturated aldehydes thiab ketones; Xaiv hydrogenation ntawm nitrobenzene tebchaw, cov ntaub ntawv qhia tau tias AU / Sio2 Puronaly Halogenation of Dehalerogenation los ntawm catalytic hydrogenolysis nyob rau hauv cov txheej txheem kev lag luam tam sim no.

Nano au catalysts yog siv dav hauv biosensors, kev ua haujlwm siab, thiab kub muaj tshuaj ruaj khov. Nws yog qhov ruaj khov ntawm cov pab pawg VIII cov ntsiab, tab sis kub nanoparticles qhia cov kev ua tau zoo heev vim muaj kev cuam tshuam me me, etlinear Optics, thiab lwm yam.

Hauv catalyzing cov kev sib xws, nano kub catalyst muaj qis dua kub thiab siab dua xaiv dua li cov kev ua haujlwm ntawm cov neeg hlau dav dav, thiab cov haujlwm tsawg tshaj plaws yog qhov siab. Cov kev ua si catalytic ntawm cov tshuaj tiv thaiv kub ntawm 200 ° C muaj ntau dua li ntawm kev ua lag luam Cuo-Zno-al2o3 catalyst.

1. Co oxidation cov tshuaj tiv thaiv

2. Cov pa dej uas tsis muaj dej

3. Kua-Calase hydrogenation cov neeg

4. Kua-theem oxidation cov tshuaj tiv thaiv, nrog rau ensylene glycole glyylene glycolation los tsim oxalic acid, thiab xaiv oxidation ntawm cov piam thaj.
