摘要

采用喷雾热解法制备氧化石墨烯薄层、氧化石墨烯:银纳米复合层、氧化石墨烯:氧化锌纳米复合层和氧化石墨烯:锌/氧化石墨烯:银双分子层。利用x射线衍射光谱、场发射扫描电镜、能量色散x射线光谱和拉曼光谱对合成的薄层进行了表征。利用Tauc方程研究并计算了薄层的光学特性和带隙。采用大肠杆菌革兰氏阴性菌对薄层进行抑菌性能研究。结果表明，在所研究的薄层中，GO:ZnO/GO:Ag双分子层对大肠杆菌生长的抑制作用最大，并能在2小时后控制细菌的生长。

ANTIBACTERIAL PROPERTIES OF GO, GO:Ag, GO:ZnO THIN LAYERS AND GO:ZnO/GO:Ag BILAYERS SYNTHESIZED BY SPRAY PYROLYSIS METHOD

Graphene oxide thin layers, graphene oxide:silver nano-composite, graphene oxide:zinc oxide nanocomposite and graphene oxide:zinc oxide/graphene oxide:silver bilayer were deposited by spray pyrolysis method. The synthesized thin layers were characterized using X-ray diffraction spectroscopy, field emission scanning electron microscope, energy dispersive x-ray spectroscopy and Raman spectroscopy. The optical properties and the band gap of the thin layers were also studied and calculated using the Tauc equation. Gram-negative bacterium of Escherichia coli was used to study the antibacterial properties of thin layers. The results showed that among the thin layers investigated, GO:ZnO/GO:Ag bilayer had the greatest effect on the inhibition of E. coli growth and was able to control the growth of bacterium after 2 hours.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
