Gutegura ibikorwa-byinshi bishyigikiwe na nano-zahabu catalizator yibanda cyane kubintu bibiri, kimwe ni ugutegura zahabu ya nano, itanga ibikorwa bya catalitike nini nubunini buto, naho ubundi ni uguhitamo gutwara, bigomba kuba bifite ubuso bunini ugereranije akarere n'imikorere myiza.hejuru cyane kandi imikoranire ikomeye hamwe na nanoparticles ya zahabu ishyigikiwe kandi iratatanye cyane hejuru yabatwara.

Ingaruka yabatwara kubikorwa bya catalitiki ya Au nanoparticles igaragarira cyane cyane mubuso bwihariye, ubushuhe bwubwikorezi ubwabwo nurwego rwimikoranire hagati yabatwara na nanopowders ya zahabu.Umwikorezi ufite SSA nini nicyo gisabwa kugirango ikwirakwizwa ryinshi rya zahabu.Ubushuhe bwubwikorezi bugena niba catisale ya zahabu izegeranya mubice binini bya zahabu mugihe cyo kubara, bityo bikagabanya ibikorwa bya catalitiki.Mubyongeyeho, imbaraga zikorana hagati yabatwara na Au nanopowders nazo ni ikintu cyingenzi kigira ingaruka kubikorwa bya catalitiki.Nimbaraga zikomeye zikorana hagati yizahabu nuwayitwaye, niko ibikorwa bya catalitiki ya catalizator ya zahabu.

Kugeza ubu, ibyinshi mubikorwa bya nano Au catalizaires birashyigikiwe.Kubaho kwinkunga ntabwo bifasha gusa gutuza kwubwoko bwa zahabu ikora gusa, ahubwo binagira uruhare runini mugutezimbere ibikorwa bya catalizator yose kubera imikoranire hagati yinkunga na nanoparticles ya zahabu.

Umubare munini wibisubizo byubushakashatsi byerekana ko nano-zahabu ifite ubushobozi bwo guhagarika imiti itandukanye y’imiti, kandi biteganijwe ko izasimbuza byimazeyo cyangwa igice igice cy’ibikoresho by’agaciro bisanzwe nka Pd na Pt mu rwego rwo guhuza imiti myiza no kuvura ibidukikije; , yerekana uburyo bwagutse bwo gusaba:

1. Oxidation Yatoranijwe

Guhitamo okiside ya alcool na aldehydes, epoxidation ya olefine, okiside ihitamo hydrocarbone, synthesis ya H2O2.

2. Hydrogenation reaction

Hydrogenation ya olefine;guhitamo hydrogenation ya aldehydes idahagije na ketone;guhitamo hydrogenation yibintu bya nitrobenzene, amakuru yerekana ko catalizike ya Au / SiO2 hamwe na nano-zahabu yapakiye 1% ishobora kumenya neza ko catalizike ikora neza ya halogenated aromatic amine hydrogenation synthesis itanga uburyo bushya bwo gukemura ikibazo cya dehalogenation na catalitiki hydrogenolysis mubikorwa byubu byinganda.

Catalizike ya Nano Au ikoreshwa cyane muri biosensor, catalizator ikora neza, kandi zahabu ifite imiti ihamye.Nibintu bihamye cyane mumatsinda ya VIII, ariko nanoparticles ya zahabu yerekana ibikorwa byiza bya catalitiki bitewe ningaruka ntoya, optique idafite umurongo, nibindi.

Mugutezimbere ibintu bisa, catalizike ya nano ya zahabu ifite ubushyuhe buke bwo guhitamo no guhitamo kurenza ibyuma rusange, kandi ibikorwa byayo bya catalitiki yubushyuhe buke ni byinshi.Igikorwa cya catalitiki ku bushyuhe bwa reaction ya 200 ° C kiri hejuru cyane ugereranije n’ubucuruzi bwa CuO-ZnO-Al2O3.

1. Imyuka ya okiside ya CO

2. Ubushyuhe buke bwamazi ya gazi ihinduka

3. Amazi ya hydrogenation reaction

4. Amazi ya okiside ya fiside, harimo na okiside ya Ethylene glycol kugirango itange aside aside, hamwe na okiside ya glucose.
