BIOMIMETIC LIGHT-HARVESTING SYNTHETIC WOODS FOR ARTIFICIAL PHOTOSYNTHESIS

摘要

PURPOSE: A light-harvesting synthesis wood for artificial photosynthesis and a manufacturing method thereof are provided to environmentally-friendly photosynthesize and to effectively recycle the optical energy. CONSTITUTION: A manufacturing method of light-harvesting synthesis woods for artificial photosynthesis comprises the following steps: dissolving synthetic wood element which is composed of cellulose, xylan and lignin and optical sensitizing material in an ion solution; obtaining a mixture by heating thereof; and obtaining the synthetic wood composite by molding the obtained mixed solution into a film form and washing thereof. The ion solution in the first step is salt existing as cation and anion in the liquid state at room temperature. In the first step, the synthetic wood element to the optical sensitizing material consisting of cellulose, xylan and lignin at a ratio of 0.1-10:1. In the first step, the optical sensitizing material is porphyrinic, light-sensitive nano particle or light-sensitive metal oxide.
