Plastic is a promising material that is generally used for various purposes. However, it’s recycling ratio is below 20% and most of them are incinerated or landfilled. These make enormous damage to human beings, such as environmental and economic problems. In this study, Carbon-Carbon (C-C) decoupling reaction of the plastic model molecule (1,3-Diphenylpropane) is demonstrated to solve this problem. Specifically, hydrogen atom abstraction is driven by several methods, which is known as the rate-determining step of C-C decoupling reaction. Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (BAPO), Cerium chloride (CeCl3), Cadmium sulfide quantum dots (CdS QDs) were used for efficient hydrogen atom abstraction and their performances are compared. As a result, CdS QDs showed the highest performance as photocatalysts and the reason is their unique characteristics such as high dispersity and large extinction coefficients. |
