摘要
以酸性红14(AR14)为碳源,Zn(NO3)2·6H2O和Ni(NO3)2·6H2O为半导体原料,通过共沉淀-吸附法合成Ni、C共掺杂ZnO复合物前驱体,并在N2中煅烧前驱体获得目标产物.同时,利用正交实验法考察影响产物光催化效率的主要因素,并采用XRD、PL、FT-IR、UV-Vis、XPS等技术对样品结构性能进行表征.结果表明,在ZnO中引入适量的Ni和C可以提高氧空位浓度,形成数量较多的碳键,利于光生电子与空穴分离.以罗丹明B(RhB)为探针分子考察了合成产物的光催化活性,结果表明,NiO/C/ZnO-5的光催化效率高于ZnO、NiO、ZnO/C、NiO/C、ZnO/NiO,也高于其他NiO/C/ZnO.
Abstract
The precursors of Ni,C co-doped ZnO were synthesized by a co-precipitation adsorption method using AR14 as carbon source,Zn(NO3)2·6H2O and Ni(NO3)2·6H2O as the raw materials of semiconductor,and the target products were obtained by calcination of precursors in N2.Effect of main factors on the photocatalytic efficiency of products were investigated by the orthogonal experimental method.The obtained products were characterized by XRD,PL,FT-IR,UV-VIS,XPS,etc.,and the results showed that the introduction of moderate Ni and C into ZnO increased the concentration of oxygen vacancies and formed a large number of carbon bonds,facilitating the separation of photoelectrons and holes.RhB was used as the probe molecule to investigate the photocatalytic activity of the resulted products and the results illustrated that the photocatalytic efficiency of NiO/C/ZnO-5 is higher than those of ZnO,NiO,ZnO/C,NiO/C,ZnO/NiO and other NiO/C/ZnO samples.
