Ag/ZnO納米纖維的制備及光催化性能(英文)
發(fā)布時(shí)間:2021-10-30 05:15
采用靜電紡絲技術(shù)及煅燒法制備了氧化鋅納米纖維,然后采用水熱法將銀納米顆粒負(fù)載到了氧化鋅納米纖維表面.利用X射線衍射(XRD)、X射線光電子能譜(XPS)、能量色散X射線光譜(EDX)、掃描電子顯微鏡(SEM)及透射電子顯微鏡(TEM)等技術(shù)對(duì)合成的Ag/ZnO納米纖維的結(jié)構(gòu)和組成進(jìn)行了表征.SEM結(jié)果表明,直徑在5100 nm之間的銀納米顆粒附著在直徑在80330 nm之間的氧化鋅纖維表面形成了異質(zhì)結(jié)構(gòu).以常見(jiàn)的有機(jī)污染物甲基橙、亞甲基藍(lán)和羅丹明B等為降解底物,對(duì)Ag/ZnO納米纖維的光催化性能進(jìn)行了表征.結(jié)果表明,負(fù)載銀納米顆粒后,復(fù)合催化劑的光催化性能明顯提高.
