The research group led by Professor Li Fengting is a fully international interdisciplinary group, based on the research of chemical molecules and materials, their basic research is combined with applied technology to solve practical environmental problems. At the same time, they combine products with technical standards, lead technological development, provide green solutions for the industry, and carry out international interdisciplinary research. This direction has been extended to hyperbranched polymer nano adsorption functional materials, and outstanding achievements have been made in the advanced treatment of drinking water, industry water, the separation and resource utilization of heavy metals from renewable energy materials. Professor Li has presided over more than 60 projects from the Ministry of science and technology, Shanghai government, UNEP, UN Habitat and the industry. He has published more than 400 papers at home and abroad, and obtained more than 90 patents from China and the United States. The technical achievements have been adopted by more than 60 companies in China to produce water treatment chemicals. Among them, the transformation results of iron salt coagulant exceed 50% of the national market. He has won the first prize of Shanghai technological invention twice, the second prize of national teaching achievement twice, and the United Nations Special Contribution Award for South-South Cooperation.
