摘要
该研究以溶剂热合成法为制备方法,通过摸索不同的反应条件,制备了一系列铌酸钙光催化纳米材料。利用XRD、TEM、UV—Vis分析手段对所得产品进行了形貌和结构表征,并通过气相光催化降解甲醛及液相光催化降解染料罗丹明B实验研究了纳米铌酸钙的光催化活性,结果表明利用此方法在160℃、13h的条件下,水热制备的纳米Ca2Nb2O7粒径为10nm左右,具有良好的光催化活性。
A series of nano-niobate Ca_2Nb_2O_7 photocatalysts were successfully synthesized by solvothermal method. XRD, TEM and UV-Vis were used to characterize the morphology and structure of the products. Photocatalysis performance of the products was also studied by decomposing gaseous formaldehyde and liquid rhodamine B solution. Ca_2Nb_2O_7 nanoparticles had a uniform particle size of 10 nm and nano-Ca_2Nb_2O_7 had a good photocatalytic activity.
