Wu, Zhenyu; Li, Xinke; Zhao, Yu; Li, Yi; Wei, Kaiqiang; Shi, Hong; Zhang, Tianyang; Huang, Hui; Liu, Yang; Kang, Zhenhui published an article in 2021. The article was titled 《Organic Semiconductor/Carbon Dot Composites for Highly Efficient Hydrogen and Hydrogen Peroxide Coproduction from Water Photosplitting》, and you may find the article in ACS Applied Materials & Interfaces.COA of Formula: C14H8Br2 The information in the text is summarized as follows:
Coprodn. of hydrogen (H2) and hydrogen peroxide (H2O2) from water splitting is one of the most promising ways to alleviate the energy crisis and environmental pollution. Here, we first show the synthesis and photocatalytic property of an organic semiconductor (DAnTMS compound) from 9,10-dibromoanthracene and trimethylsilylacetylene. Then, a metal-free photocatalyst of a DAnTMS/carbon dot (DAnTMS/CD) composite was designed and fabricated, which achieved the efficient photocatalytic production of H2 and H2O2 without usage of any organic solvents and sacrificial agents. Under visible light, the DAnTMS/CD composite could produce H2O2 with a maximum rate of 396.7 μmol g-1 h-1 and H2 with a maximum rate of 365.0 μmol g-1 h-1 in pure water. Transient photovoltage tests showed that CDs changed the interface electron transfer kinetics and served as the active site for highly efficient H2 evolution. This work provided a deep insight into the function of CDs in regulating the catalytic property of organic photocatalysts. After reading the article, we found that the author used 9,10-Dibromoanthracene(cas: 523-27-3COA of Formula: C14H8Br2)
9,10-Dibromoanthracene(cas: 523-27-3) is a dibrominated polycyclic aromatic hydrocarbon (PAH). 9,10-Dibromoanthracene is often used as an energy acceptor and activator in reactions that produce chemiluminescence.COA of Formula: C14H8Br2
