Cooperation between Xi'an Jiaotong University and Beijing University of chemical technology reveals the application potential of carbon point materials in energy storage and transformation

Carbon point materials are a kind of quasi-zero dimensional carbon nanoparticles with cold luminescence characteristics They are the rising stars of carbon nano materials family In recent years, they have been widely concerned at home and abroad Although some traditional luminescent materials, such as organic dyes, semiconductor quantum dots and rare earth fluorescent nano materials, have been developed and applied in practical production and life (such as energy-saving lamps, displays, luminescent coatings, etc.), there are some defects to some extent, such as high toxicity, poor light stability, high price, etc In contrast, carbon point materials have many advantages, such as wide source, low price, low toxicity, good light stability, no light flicker, large two-photon absorption area, adjustable band structure and so on Hu Chao research group of Xi'an Jiaotong University and Professor Qiu Jieshan of Beijing University of Chemical Technology cooperated to design and prepare carbon point materials by adjusting the size and crystallinity, surface modification and heteroatom doping structural control strategies, and discussed their applications in the fields of light-emitting diode, photocatalysis, photocatalysis and solar cell In addition, the application of carbon dots in electrocatalysis, secondary battery and supercapacitor is also reviewed by using the abundant surface defect sites and flexible structural tunability of carbon dots, which will provide guidance for the future research work of carbon dots in the field of energy storage and conversion Recently, the research results were published online in the Journal of Chemical Society Reviews (DOI: 10.1039 / c8cs00750k) under the title of design and fabrication of carbon dots for energy conversion and storage, and were recommended as the highlight of the back cover article The above work has been supported by the National Natural Science Fund, Shaanxi Natural Science Fund, China Postdoctoral fund and the basic scientific research business fees of central universities.
