II. Inqubo yanamuhla ethuthukisiwe (indlela yeSolvothermal)
Indlela yeSolvothermal iyindlela ejwayelekile yokukhiqiza i-nanoscale znte, enikeza izinzuzo ezinjengesayizi alawulwa yizinhlayiyana kanye nokusetshenziswa kwamandla okuphansi.
1. Izinto zokwakha ezivuthiwe nama-sol
• Abaqapheli: I-Zinc Nitrate (ZN (No₃) ₂) ne-sodium arterite (NA₂TEO₃) noma i-Telturium Powder (TE).
• Ukunciphisa ama-ejenti: i-hydrazine hydrate (nhh₄ · h₂o) noma i-sodium borohydride (NABH₄).
• Solvents: I-Ethyleniane (EDA) noma amanzi e-deinized (i-DI amanzi).
2. Ukugeleza kwenqubo
• Isinyathelo 1: Ukuchithwa kwangaphambili
o Dislove Zn (No₃) ₂ ne-NA₂TEO₃ ngesilinganiso esingu-1: 1 ku-solvent ngaphansi kokuvusa.
• Isinyathelo 2: ukulungiswa kokunciphisa
o Faka umenzi oncishisiwe (isib.
Izimo Zokusabela:
Ukushisa: 180-220 ° C
Isikhathi: amahora angu-12- 24
Ingcindezelo: Ukuzenzela ngokwakho (3-5 MPA)
o Ukusabela Equation: I-ZN2 ++ I-Agent → I-ZNTE + BRPRODUCTS (isib. H₂o, N₂) ZNTE3
• Isinyathelo 3: ukwelashwa ngemuva
O I-centriphuruge ukuhlukanisa umkhiqizo, geza izikhathi ezi-3-5 nge-ethanol namanzi e-di.
o womile ngaphansi kwe-vacuum (60-80 ° C amahora 4-6).
3. Amapharamitha asemqoka
• Ukuhlushwa kwangaphambili: 0.1-0.5 mol / l
• Ukulawulwa kwe-PH: 9-11 (Izimo ze-Alkaline Zifuna Ukuphendula)
• Ukulawulwa kosayizi wezinhlayiyana: Lungisa ngohlobo lwe-solvent (isib. Eda uveza ama-nanowires; Isigaba se-aqued siveza ama-nanoparticles).
