Patent number: 11565241Abstract: A method for in-situ generation of nanoflower-like manganese dioxide catalyst on filter material is provided. The method comprises: immersing a filter material in a solution containing sodium lauryl sulfate and nitric acid; first modifying the surface of the filter material by using the sodium lauryl sulfate so that a charge layer is wound around the surface of the filter material and tightly absorbs H+ in an acid solution; and then adding potassium permanganate as an oxidant to react with H30 on the surface of the filter material to generate nano flower-like manganese dioxide in situ on the surface of the filter material, so as to obtain a composite filter material having a denitration function.Type: GrantFiled: September 12, 2016Date of Patent: January 31, 2023Assignee: FUZHOU UNIVERSITYInventors: Yuying Zheng, Jian Chen

Publication number: 20220314166Abstract: The present invention belongs to the technical field of functional organic macromolecule composite catalysts and involves the preparation of a nitrogen-doped lattice macromolecule composite loaded with an efficient denitrification and sulfur resistance catalyst, firstly using the method of adding metal salts to make a large amount of Ce3+, Ce4+, Sn3+ and Sn4+ ions accumulate around the cyanuric acid molecule. Afterwards, 2,4,6-triaminopyrimidine and cytosine were added to graft with the cyanuric acid to produce the N-doped macromolecule in the first stage. After that, potassium permanganate was used as the oxidizing agent, and redox reaction occurred on the surface of N-doped macromolecules, so that the manganese cerium tin catalyst was grown in situ on the surface of N-doped macromolecules, and finally calcined at once to cross-link the N-doped macromolecules to generate catalyst composites. The catalysts described in this invention have higher efficient NOx reduction and sulfur resistance performance.Type: ApplicationFiled: July 10, 2020Publication date: October 6, 2022Applicant: FU ZHOU UNIVERSITYInventors: Yuying ZHENG, Weijie ZHENG

Patent number: 10557043Abstract: This present invention discloses a temperature-sensitive nano-silver controlled release antibacterial coating composite, which is comprises: water, acrylic, polyurethane resin, temperature-sensitive nano-silver controlled release antibacterial agent, dispersant, curing agent, defoamer, filming additive and leveling agent. By adsorbing nano silver particles into the pores of mesoporous SiO2 modified by poly N-isopropyl acrylamide, we successfully prepared a temperature-sensitive nano-silver controlled release antibacterial agent. By adding the prepared agent to the conventional coating composite, we achieved “on-off” control of the antibacterial properties of coating composite. Through the control of temperature, the release of nano-silver in the mesoporous nano-silica of the coating film layer is controlled.Type: GrantFiled: January 15, 2018Date of Patent: February 11, 2020Assignee: FU ZHOU UNIVERSITInventors: Yuying Zheng, Liangen Huang

Patent number: 10138337Abstract: This present invention discloses a polymer/potassium permanganate composite film obtainable by a process comprising the steps of using silane coupling agent for surface treatment of potassium permanganate, mixing 0.15-0.75 g of modified potassium permanganate with 10-20 g of polymers together to obtain a mixture, and coating the mixture to obtain a composite film. The composite film can absorb ethylene generated by fruit, thus extending fruit ripening time, keeping fruit fresh. It can be widely used as food packaging materials. The composite film also has a good oxygen barrier property and has a good efficiency to remove bacteria. Therefore it can be widely used in the pharmaceutical industry. The preparation method is scientifically sound, simple, and has high level of operability, thus making it possible for batch preparation.Type: GrantFiled: January 4, 2015Date of Patent: November 27, 2018Assignee: FUZHOU UNIVERSITYInventors: Yuying Zheng, Zhimin Fan
