Luminous Great Wall

Since ancient times, due to geological changes and other reasons, many relics have been submerged under water, and the Panjiakou Great Wall is one of them. We hope to repair the Great Wall in the form of a net of light, so that the Great Wall can be seen by people in another form. In this way, we hope to repair the spiritual and cultural loss caused by the Great Wall sinking under water

The scheme attempts to complement the Great Wall through the light-emitting network structure, which contains photocatalytic nanorods with water purification capacity, and Bi8(CrO4)O11 nanorods with broad spectral activity, whose spectral absorption range can be extended to 678 nm, which can use light energy to degrade pollutants. The bioluminescence produced by dinoflagellates can facilitate the interpretation of pollutants in the water by nanorods. The outermost layer is a transparent and permeable material that allows water to flow in and out while preventing algae from spreading into the water and causing biological contamination.
