He is mainly engaged in the research of lignin high value and high water absorption materials. As a project leader, he has undertaken a number of projects under the National Key Research and Development Program (NKRDP), a number of top-level projects under the National Natural Science Program (NNSP), and three projects under the Civil-Military Integration Program. In recent years, he has published more than 100 SCI papers in international journals such as J Control Release and Ind Crops Prod as the first author or corresponding author, and has authorized or applied for 40 invention patents, and has won two provincial and ministerial-level science and technology awards. EducationWork ExperienceSocial PositionSocial ActivitiesResearchI mainly focus on the academic research and practical application of salt-resistant and highly absorbent resins and high value utilization of lignin, and have made some important academic contributions and significant innovative achievements. (1) Realization of highly selective preparation of monophenols with aliphatic hydroxyl residues by reductive catalytic fractionation Two reduction-catalyzed fractionation techniques, based on Pd/C, Ru/C and other noble metal catalysts and H2 as hydrogen donor, and based on non-precious metal Raney Ni catalyst and isopropanol as hydrogen donor, have been studied to realize the preparation of low molecular weight reductive lignin oligomers and aliphatic hydroxyl-residue-rich lignin monophenols from poplar, pine, corn stover and other raw materials. (2) Developed a basic synthesis process for the preparation of non-isocyanate polyurethane (NIPU) from different biomass raw materials. The enzyme-UIO-66-NH2 co-catalyzed fatty acid preparation process for cyclic carbonate was developed, and microbial oil substrate was applied to prepare NIPU, and the synthetic method of applying cellulose and starch-rich sweet potato residue to prepare cyclic carbonate and NIPU was opened, and the material was applied to food preservation, and furthermore, graded lignin was applied as raw material, and the precursor of lignin-based cyclic carbonate was synthesized via a three-step process, and the precursor was synthesized. Then the lignin-based NIPU was synthesized, and the antibacterial and UV-resistant properties of the material were investigated. (3) Application of Highly Absorbent Gel for Crop Water Saving in Desert Irrigation Areas Develop the following water retaining agent preparation process, aspartic acid raw materials, synthesized molecular weight of up to 15-20 Kda polyamino acid fertilizer synergist, epoxide as a crosslinking agent to produce polyamino acid water retaining agent, rationalize the process conditions and the product of the law between the rate of water absorption, and then use a variety of means to reduce the cost of 6.5-14%, and the establishment of a kiloton production unit.
