○ A research team led by Professor Lee Jae-joon of Dongguk University and Professor Lim Gyu of State University of New York College of Environmental Science and Forestry developed a system capable of photoelectrochemically decomposing lignin, a representative lignocellulosic waste, at room temperature by fusing a photoelectrode system based on a responsive photovoltaic cell and an organic catalyst.


○ Unlike the existing catalyst-based electrochemical decomposition method, the joint research team led by Kang Hyeong-Cheol and Kim Saerona (co-first authors) achieved conditions for selective oxidative decomposition even at room temperature by utilizing a photoelectrochemical reaction using an organic dye-based sensitized photovoltaic cell.


○ "The results of this study are expected to contribute to the use of various waste resources and the resolution of environmental pollution problems without additional energy consumption in the future by utilizing solar energy for the eco-friendly decomposition reactions of waste plastics and biomass," said Professor Lee Jae-joon.
