Patent number: 11623210Abstract: A method for preparing a silicate/carbon composite from attapulgite, and use of the silicate/carbon composite are disclosed. The preparation method includes: (1) with attapulgite as a raw material, preparing SiO2 with a special structure; (2) dispersing the prepared SiO2 in water to obtain a suspension, and subjecting the suspension to ultrasonic dispersion; dissolving a metal nitrate in the suspension, adding NH4Cl, and adding ammonia water dropwise to the suspension; and adding sucrose to obtain a suspension; (3) subjecting the suspension to microwave hydrothermal reaction; after the reaction is completed, centrifuging a resulting system; and separating a resulting solid; and (4) subjecting the solid to high-temperature calcination in a muffle furnace, and grinding a resulting product to obtain the silicate/carbon composite, which can be used in photocatalytic ammonia synthesis.Type: GrantFiled: November 10, 2020Date of Patent: April 11, 2023Assignee: CHANGZHOU UNIVERSITYInventors: Xiazhang Li, Haiguang Zhang, Xini Chu, Jie Zhu, Xiangyu Yan, Shixiang Zuo, Chao Yao, Wenjie Liu, Huihui Mao

Patent number: 11583808Abstract: A method for preparation of conductive polymer/carbon nanotube (CNT) composite nanofiltration (NF) membrane and the use thereof. This conductive polymer/CNT composite NF membrane is obtained by polymerizing conductive polymer into a CNT membrane and then in-situ cross-linking with glutaraldehyde under acidic condition. The synthetic method for the conductive polymer/CNT composite NF membrane is simple and has no need of expensive equipment. The prepared membrane has controllable membrane structure and possesses superior electrical conductivity and electrochemical stability. The membrane can couple with electrochemistry for electrically assisted filtration. With the electrical assistance, the membrane can achieve improved ion rejection performance while retaining high permeability by enhancement of membrane surface charge density, which alleviates the permeability-selectivity trade-off.Type: GrantFiled: December 18, 2018Date of Patent: February 21, 2023Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Xie Quan, Haiguang Zhang, Shuo Chen, Hongtao Yu
