Diyaarinta dhaqdhaqaaqa sare ee la taageeray nano-dahab-dahab ah ayaa inta badan tixgelinaya laba dhinac, mid waa diyaarinta dahabka nano, kaas oo hubinaya dhaqdhaqaaqa sare ee cabbirka yar, kan kalena waa xulashada side, kaas oo ah in uu leeyahay dusha sare oo gaar ah. deegaanka iyo waxqabadka wanaagsan.qoyan sare iyo isdhexgalka xooggan ee nanoparticles dahab ah ee la taageeray waxayna aad ugu kala firdhisan yihiin dusha sare ee side.

Saamaynta uu sidaha ku leeyahay dhaqdhaqaaqa catalytic ee Au nanoparticles ayaa inta badan ka muuqda aagga dusha sare ee gaarka ah, qoyaanka side laftiisa iyo heerka isdhexgalka ka dhexeeya side iyo nanopowders dahabka.Qaade leh SSA weyn ayaa shardi u ah kala firdhinta sare ee walxaha dahabka ah.Qoynta sidaha ayaa go'aaminaysa in dahabka dahabka ahi isu geyn doono qaybo dahab ah oo waaweyn inta lagu jiro habka calcination, taas oo hoos u dhigaysa dhaqdhaqaaqiisa catalytic.Intaa waxaa dheer, xoogga isdhexgalka ee u dhexeeya side iyo Au nanopowders sidoo kale waa arrin muhiim ah oo saameeya dhaqdhaqaaqa firfircoonida.Marka ay sii xoogeysato xoogga isdhexgalka ee u dhexeeya qaybaha dahabka iyo sidaha, ayaa sare u kacaysa dhaqdhaqaaqa kicinta ee kicinta dahabka.

Waqtigan xaadirka ah, badi nano Au kicinyaasha aadka u fir fircoon waa la taageeraa.Jiritaanka taageerada kaliya maaha mid ku habboon xasilloonida noocyada dahabka ah ee firfircoon, laakiin sidoo kale waxay door muhiim ah ka ciyaartaa kor u qaadida dhaqdhaqaaqa kicinta oo dhan sababtoo ah isdhexgalka ka dhexeeya taageerada iyo nanoparticles dahabka ah.

Natiijooyin cilmi-baaris oo tiro badan ayaa muujinaya in nano-dahab uu awood u leeyahay inuu kiciyo fal-celin kiimiko oo kala duwan, waxaana la filayaa inuu si buuxda ama qayb ahaan u beddelo kicinta birta qaaliga ah ee jira sida Pd iyo Pt ee dhinacyada isku-dhafka kiimikada iyo daaweynta deegaanka. , oo muujinaya rajooyin ballaadhan:

1. Oxidation Xul ah

Oxidation-ka xulashada khamriga iyo aldehydes, epoxidation of olefins, oksaydhka xulashada ee hydrocarbons, isku-darka H2O2.

2. Dareen-celinta hydrogenation

Hydrogenation of olefins;hydrogenation-ka xulashada ee aldehydes iyo ketones aan saturated;hydrogenation xulashada xeryahooda nitrobenzene, xogtu waxay muujinaysaa in Au / SiO2 kicinta leh nano-dahab loading ah 1% ay garan karaan catalysis hufan ee saafi-sare-nadiifinta sare ee aromatic amines hydrogenation synthesis siinayaa fursad cusub si loo xaliyo dhibaatada dehalogenation by catalytic. hydrogenolysis ee habka warshadaha hadda.

Kaaliyeyaasha Nano Au ayaa si weyn loogu isticmaalaa biosensors, kicinta waxtarka sare leh, dahabkuna wuxuu leeyahay xasilooni kiimikaad oo wanaagsan.Waa tan ugu xasilloon xubnaha kooxda VIII, laakiin nanoparticles dahabku waxay muujinayaan firfircooni firfircoon oo aad u wanaagsan taas oo ay ugu wacan tahay saamaynta cabbirka yar, indhaha aan tooska ahayn, iwm.

Xakamaynta falcelinta la midka ah, kicinta dahabka nano waxay leedahay heerkul falcelin hoose iyo xulashada ka sarraysa marka loo eego kicinta birta guud, iyo firfircoonideeda heerkulka hoose waa mid sarreeya.Dhaqdhaqaaqa catalytic ee heerkulka falcelinta ee 200 °C aad ayuu uga sarreeyaa kicinta ganacsiga ee CuO-ZnO-Al2O3.

1. falcelinta oksaydhka CO

2. falcelinta gaaska biyaha heerkulka hooseeya

3. falcelinta hydrogenation-ka dareeraha ah

4. Dareen-celinta oxidation-ka dareeraha ah, oo ay ku jiraan oxidation ethylene glycol si loo soo saaro oxalic acid, iyo oksaydhka xulashada gulukooska.
