英文摘要： Electrocatalytic conversion of carbon dioxide is currently a hot topic in interdisciplinary research of electrochemistry, environmental science and energy engineering, but it is still has problems of complex products, poor product selectivity, low efficiency or high energy consumption. The project intends to innovatively prepare N, F modified low-cost high-performance carbon air cathode by rolling method, and to develop novel photosynthetic algal microbial fuel cell system, fulfilling electricity production and efficient conversion of carbon dioxide to the algae renewable energy at the same time. It will clarify the regulatory mechanism for non-metallic catalyst layer modification, and master the key to the new cathode rolling preparation. It will construct and optimize the new photosynthetic algal microbial fuel cell, finding the way to strengthen the fixation and transformation of carbon dioxide, revealing the key influencing parameters for algae growth and oil production, and clarifying the new mechanism of photosynthetic and electrocatalytic conversion of carbon dioxide to algae. It will further study the feasibility and limitations of this new photosynthetic algae microbial fuel cell application to the flue gas carbon dioxide conversion to provide a technical support and new ways for their practical application. This would help our country to fulfill its international obligations to reduce carbon dioxide, reduce greenhouse gas emission and environmental impact, and develop renewable energy, thus it is of important strategic significance, academic research value and application prospects.
