“In the future, only sunlight, carbon dioxide, and water are needed to produce automotive fuels, polymer materials, and pharmaceuticals.†On June 3, at the 2015 International Symposium on Optoelectronics, Materials, and Energy, the world’s top materials scientists, Professor Yang Peidong, an academician of the American Academy of Arts and Sciences, disclosed this hopeful news. Yang Peidong introduced that the system he is studying is similar to the green leaf photosynthesis system, except that the photosynthesis products of the green leaves are oxygen and carbohydrates, and the products of this system are oxygen and other chemical substances, so it is also called an artificial photosynthesis system. “In a device consisting of semiconductor silicon and a catalyst, sunlight reacts with carbon dioxide and water to produce butanol, polymer materials, pharmaceuticals, and other chemicals that can be used in automotive fuels.†Prof. Yang told reporters that traditional raw materials for the production of chemicals such as oil are all obtained from the ground, and the raw materials used by the artificial photosynthesis system he studies, such as carbon dioxide, can be enriched from the environment, which will revolutionize the existing industry. effect. The chemicals produced through the system, such as butanol, can be used as fuel for automobiles to obtain carbon dioxide and water, which can be recycled and used almost without pollution. At the same time, carbon dioxide generated by driving and generating electricity can reduce greenhouse gases and improve global warming after enrichment. It is understood that the current energy conversion rate of the artificial photosynthesis system has reached 0.4%. “This efficiency is not low, but the photosynthesis conversion rate of green leaves is only 0.3%. Next we are going to improve the catalyst and increase the efficiency to 2% to 3%, and when the efficiency reaches 5%, it can be mass produced.†At the seminar, the new graphene negative electrode material developed by Professor Yu Wei of Nanyang Technological University, Singapore, and the team of academician Huang Wei of the University of Nangong University researched the world’s first room temperature organic long afterglow material that can be used for RMB anti-counterfeiting. The results have also received a lot of attention. The 2015 International Symposium on Optoelectronics, Materials and Energy (iSOME-2015), held in Nanjing, lasted for four days and was jointly organized by the National Jiangsu Advanced Biotechnology and Chemical Manufacturing Collaborative Innovation Center and Nanjing University of Technology. More than 30 well-known scholars from the United States, Germany, Australia, Singapore, Japan, South Korea, India, Hong Kong and other countries and regions will exchange organic semiconductors, perovskite solar cells, and up-conversion nanometers with nearly 200 domestic and foreign participants. Luminous, nano-functional materials. Conjugated polymers, phosphorescent complexes and other cutting-edge issues.
