摘要:
采用水热法在SiO-2纳米微球表面修饰Ag纳米颗粒,制备二元SiO2/Ag复合微球(SiO-2/Ag CMs)。通过改变AgNO-3用量,调控Ag纳米颗粒的尺寸及分布,并利用透射电子显微镜、X射线衍射等技术探究产物的表面形貌、微观结构及组成。相比于单分散性的SiO-2微球和Ag纳米颗粒,SiO-2/Ag CMs的光吸收峰发生明显红移,且具有较宽的SPR光吸收范围。以亚甲基蓝(MB)为有机染料模型,研究SiO-2/Ag CMs对MB的光催化降解性能,结果表明:SiO-2/Ag CMs光催化剂催化性能优于SiO-2纳米微球及Ag纳米颗粒;当AgNO-3用量为0.10 g时所制备的SiO-2/Ag CMs表现出较为优异的光催化活性,且在可见光照射80 min时其催化效率达到97.7%。
