The research team of Professor Jun Young-si (School of Chemical Engineering) succeeded in developing and the fiberization of the first liquid crystal phase of graphitic carbon nitride, which is a photocatalytic material necessary for hydrogen production and fine dust removal.

The results of the research conducted by Professor Jun and Dr. Jeong Hyun-su (Korea Institute of Science and Technology), and Dr. Kim Yun-ho (Korea Research Institute of Chemical Technology) were published in the online edition of Materials Horizons (which has an Impact Factor of 14.356, which is in the top 5.631% of the JRC index).

Among various ways to produce hydrogen, photocatalytic technology is considered ideal in respect to both environmental and economic aspects. Photocatalytic technology uses solar energy to decompose water into hydrogen and oxygen.

Graphitic carbon nitride is a photocatalytic material that is suitable for absorbing visible light. It has gained attention recently due to increased demand for hydrogen production as a fuel for next generation vehicles, as well as facilitating the removal of fine dust, which has become a serious social problem. It also has potential for application to, among others, water purification.

In addition, graphitic carbon nitride has been proven advantageous thanks to its simple manufacturing process, excellent price competitiveness, and high thermal and chemical stability. Various research has been conducted for higher application efficiency in many developed countries.

The research project of Professor Jun has been cosponsored by the following projects of renowned institutions: the Open Research Program of the Korea Institute of Science and Technology, as a major research project of Korea Research Institute of Chemical Technology, and Nanomaterial Technology Development Project, the Nano-based Soft-electronics Research Group project, the Creative convergence research project (CAP), and the Basic Research Laboratory (BRL) project of the Korea Research Foundation.
