中文摘要: |
利用紫外-可见光谱(UV-vis)原位监测光化学还原法合成Ag@AgHSiW催化剂合成的4个阶段,通过X射线能量色散谱(EDS)对其形貌进行了表征,通过自动进样,测试甲基蓝的可见光催化降解,分析在反应过程中银的表面等离子体共振吸收(SPR)峰与甲基蓝(MB)的特征吸收峰之间的变化关系,并初步探讨了纳米Ag颗粒与杂多阴离子(HPA)之间的协同光催化反应作用机理. |
英文摘要: |
Photochemical synthesis of the Ag@AgHSiW were characterized by energy dispersive spectrometry (EDS). The procedure of the Ag@AgHSiW synthesis and the visible light photocatalytic degradation of methylene blue (MB) were measured with the ultraviolet visible absorption spectrometry. Finally,the mechanism for the enhancement of photocatalytic activity of the Ag and heteropolyanion were discussed. |
