Ukulungiswa komsebenzi ophezulu oxhaswayo we-nano-gold catalysts ubukhulu becala kuqwalaselwa imiba emibini, enye kukulungiswa kwe-nano yegolide, eqinisekisa umsebenzi ophezulu we-catalytic kunye nobukhulu obuncinci, kwaye enye ikhethwa ngumthwali, omele ube nomhlaba othile omkhulu. indawo kunye nokusebenza kakuhle.ukumanzi okuphezulu kunye nokusebenzisana okunamandla kunye ne-nanoparticles yegolide exhaswayo kwaye zihlakazeke kakhulu kumphezulu womthwali.

Impembelelo yomphathiswa kumsebenzi we-catalytic we-Au nanoparticles ibonakaliswe ngokukodwa kwindawo ethile yomhlaba, ukumanzi kwe-carrier ngokwayo kunye neqondo lokusebenzisana phakathi komphathi kunye ne-nanopowders yegolide.Umthwali one-SSA enkulu yimfuneko yokusasazeka okuphezulu kwamasuntswana egolide.Ubumanzi bomntu ophetheyo bumisela ukuba ingaba i-catalyst yegolide iya kuhlangana ibe ngamasuntswana egolide amakhulu ngexesha lenkqubo yokubala, ngaloo ndlela inciphisa umsebenzi wayo we-catalytic.Ukongezelela, amandla okusebenzisana phakathi komthwali kunye ne-Au nanopowders nayo yinto ephambili echaphazela umsebenzi we-catalytic.Okona kunamandla amandla okusebenzisana phakathi kwamasuntswana egolide kunye nomthwali, kokukhona uphezulu umsebenzi we-catalytic we-catalyst yegolide.

Okwangoku, uninzi lwe-nano Au catalysts esebenzayo kakhulu iyaxhaswa.Ubukho benkxaso abuncedi nje kuphela ukuzinza kweentlobo zegolide ezisebenzayo, kodwa kwakhona kudlala indima ebalulekileyo ekukhuthazeni umsebenzi we-catalyst yonke ngenxa yentsebenziswano phakathi kwenkxaso kunye ne-nanoparticles yegolide.

Inani elikhulu leziphumo zophando zibonisa ukuba i-nano-igolide inamandla okwenza iintlobo ezahlukeneyo zeekhemikhali, kwaye kulindeleke ukuba ithathe indawo ngokupheleleyo okanye ngokuyinxenye i-catalysts yentsimbi exabisekileyo ekhoyo njenge-Pd kunye ne-Pt kwiinkalo ze-chemical synthesis kunye nonyango lokusingqongileyo. , ebonisa amathuba osetyenziso olubanzi:

1. I-Oxidation ekhethiweyo

I-oxidation ekhethiweyo yee-alcohol kunye ne-aldehydes, i-epoxidation ye-olefins, i-oxidation ekhethiweyo yee-hydrocarbons, i-synthesis ye-H2O2.

2. Ukusabela kwe-Hydrogenation

I-Hydrogenation ye-olefins;i-hydrogenation ekhethiweyo ye-aldehydes engaxutywanga kunye neetoni;i-hydrogenation ekhethiweyo yeekhompawundi ze-nitrobenzene, idatha ibonisa ukuba i-Au/SiO2 i-catalyst ene-nano-gold loading ye-1% inokuqonda i-catalysis esebenzayo ye-high-purity halogenated aromatics amines hydrogenation synthesis inika ithuba elitsha lokusombulula ingxaki ye-dehalogenation nge-catalytic. i-hydrogenolysis kwinkqubo yangoku yoshishino.

I-Nano Au catalysts isetyenziswa ngokubanzi kwi-biosensors, i-catalysts ephezulu, kunye negolide inozinzo olulungileyo lwekhemikhali.Yeyona nto izinzile phakathi kwezinto zeqela le-VIII, kodwa i-nanoparticles yegolide ibonisa umsebenzi obalaseleyo we-catalytic ngenxa yeziphumo ezincinci, i-nonlinear optics, njl.

Ekwenzeni ukusabela okufanayo, i-nano catalyst yegolide inobushushu obuphantsi bokusabela kunye nokukhetha okuphezulu kunezixhobo zentsimbi eziqhelekileyo, kwaye umsebenzi wayo wobushushu obuphantsi uphezulu.Umsebenzi we-catalytic kwiqondo lobushushu le-reaction ye-200 °C iphezulu kakhulu kunelo lorhwebo lwe-CuO-ZnO-Al2O3 catalyst.

1. I-CO oxidation reaction

2. Ubushushu obuphantsi bokutshintsha kwegesi yamanzi

3. Ulwelo-isigaba hydrogenation reaction

4. I-Liquid-phase oxidation reactions, kubandakanywa i-ethylene glycol oxidation ukuvelisa i-oxalic acid, kunye ne-oxidation ekhethiweyo ye-glucose.
