Abstract

In this study, AgCu@MWCNT nanocatalyst was synthesized by following a series of physicochemical hydrothermal processes. The obtained catalysts of AgCu@MWCNT were characterized by advanced spectroscopic methods. AgCu@ MWCNT nanocatalyst used for degradation of MB was investigated under ultrasonic irradiation, and AgCu@MWCNT nanocatalyst exhibited an excellent sonocatalytic activity function. The effects on sonocatalytic activity were investigated with various experimental parameters. Percent degradation of MB after sonocatalytic activity was found to be 90.2% for 60 min. Findings showed that in the presence of AgCu@MWCNT nanocatalysts, OH and O2% - radicals were determined to be the main molecules in the degradation of MB under sonocatalytic conditions. The intermediate by-products of the paint formed in the degradation process were characterized by GC-MS technique. Overall, based on the results, AgCu@MWCNT nanocatalysts were detected as an effective nanocatalyst for degradation of MB using the ultrasonic process method.

抽象的

在本研究中，通过一系列的物理化学水热过程合成了AgCu @ MWCNT纳米催化剂。用先进的光谱方法对得到的AgCu @ MWCNT催化剂进行了表征。在超声辐射下研究了用于降解MB的AgCu @ MWCNT纳米催化剂，并且AgCu @ MWCNT纳米催化剂具有优异的声催化活性功能。用各种实验参数研究了对声催化活性的影响。发现在声催化活性后60分钟，MB的降解百分率为90.2％。结果表明，在AgCu @ MWCNT纳米催化剂的存在下，OH和O2％-自由基被确定为在声催化条件下MB降解的主要分子。利用GC-MS技术对降解过程中形成的涂料中间产物进行了表征。总体而言，基于该结果，使用超声处理方法将AgCu @ MWCNT纳米催化剂检测为降解MB的有效纳米催化剂。
