分級ZnO納米棒組裝空心超結構催化及熒光應用

不知道小木蟲里有沒有前輩做過這個課題Hierarchical ZnO Nanorod-Assembled Hollow Superstructures for Catalytic and Photoluminescence Applications。我在做這個實驗時,按照實驗步驟在加入CMC后,溶液中出現(xiàn)了許多極小細微褐色物質,不知道是什么物質。 部分原文:In a typical synthesis, 0.44 g of ZnAc2 3 2H2O (analytically pure) was dissolved in 8 mL of deionized water with magnetic stirring, and then 2 mL of ammonia solution (25%, analytically pure) was added. After that, 10 mL of 2.8 g/L CMC (300-800 mPa 3 S, chemically pure) aqueous solution was added dropwise into the solution containing zinc acetate and ammonia. After 5 min of stirring, the mixture was transferred to and sealed in a 50 mL Teflon-lined autoclave, kept at 120 C for 2 h, and finally cooled to roomtemperature. The precipitatewas collected by centrifugation (4000 rpm, 3 min), washed alternately with deionized water and ethanol, and dried in air under ambient conditions. |
