| For referring convenience, we term the products as ZnO-GNx-T, with x=0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.5, 0.8 and T=150, 200, 250, 300 denoting the weight percentage of graphene and the calcination temperature, respectively. ZnO-GN0.1-200 was prepared by an in situ chemical precipitation method . Briefly, Zn(NO3)2 (0.01mol) was dissolved in distilled water (50 ml) with vigorous stirring in an ice-bath (a). GO (0.0904 g) was exfoliated in distilled water (100 ml) with ultrasonic treatment about an hour to form a light-brown solution (b). Subsequently, (b) was droped into (a) with continuous stirring. Then the aqueous solution of 1M KOH was dropwise added into the above mixture until the pH up to 8.5. After aging for 12 h, the product was separated by suction filtration and rinsed with distilled water several times, and then the product was dried at 60°C for 12 h under vacuum. Then the powder sample obtained was calcined at 200°C for 5h in air. The resultant product was obtained. |

為了便于引用，我們稱這些產(chǎn)品為 ZnO-GNx-T,此處x=0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.5, 0.8 及 T=150, 200, 250, 300分別指單層石墨片的重量百分比及煅燒溫度。ZnO-GN0.1-200是通過一個(gè)原位化學(xué)沉淀法制備的。簡(jiǎn)短地說，把Zn(NO3)2 (0.01mol) 溶解在蒸餾水里(50 ml)并在冰浴器內(nèi)加以很好的攪拌形成（a）。把GO (0.0904 g)剝落到蒸餾水里(100 ml)并用超聲波處理約一小時(shí)以形成一個(gè)淡褐色的溶液（b)。隨后，滴入溶液（b)到溶液（a）并伴以不間斷的攪拌。然后將水相的1M KOH滴入到上述混合物中，直到pH值達(dá)到8.5。時(shí)效12小時(shí)后，用抽濾分離該產(chǎn)品并用蒸餾水?dāng)?shù)次漂洗， 然后在真空條件和60攝氏度下把該產(chǎn)品干燥12小時(shí)。之后這樣得到的粉樣在200攝氏度下空氣中煅燒5小時(shí)，就得到了最終產(chǎn)品。 不夠?qū)I(yè)，供參考 |
