MICROWAVE ENABLED RAPID FABRICATION OF PHOSPHORS AND PHOSPHORS CO-DOPED GRAPHITIC CARBON WITH HIERARCHY POROUS STRUCTURES

摘要

The pivotal role of catalytic materials in various industries is unambiguously demonstrated by the fact that up to 90% of commercially available chemical products involve the use of catalysts at some production stage. However, most catalytic materials were developed based on toxic and/or precious metals, which are unsustainable and possess environmental risks. In the drive towards green and sustainable chemistry, there is an increasing interest in developing new carbon-based materials that are benign, abundant, readily available, and metal free to act as catalysts for chemical synthesis. Compared to traditional metal based catalysts, carbon based materials provide additional advantages because of the existence of giant π structures promotes strong interactions with various reactants. More importantly, its physicochemical and electronic properties, which in principle determine the catalytic properties of a material, can be tailored and fine-tuned by molecular engineering and/or heteroatomic doping.
