MnO2-ZIF-8-SiO2多孔纳米纤维的制备及甲醛催化性能研究
Preparation of MnO2-ZIF-8-SiO2 porous nanofibers and study on catalytic performance of formaldehyde
摘要
Abstract
In order to solve the problem of low efficiency of nano-catalyst materials at low formaldehyde con-centration,a functional composite nano-fiber material was designed to improve the catalytic efficiency of form-aldehyde by combining adsorption and degradation of formaldehyde.ZIF-8 nanoparticles were grown on SiO2 nanofibers by hydrothermal in-situ growth method,MnO2-ZIF-8-SiO2 porous nanofiber material was prepared by in-situ synthesis of manganite type MnO2.A functional composite nanofiber material integrating formalde-hyde adsorption and degradation catalysis were implemented,which has important research value in gas purifi-cation.The synergistic catalytic degradation of formaldehyde by ZIF-8 nanoparticles and manganite MnO2 was studied.The results showed that when ZIF-8-SiO2 grew for 8 h,the best growth time is that ZIF-8 on fiber pres-ents cubic structure and is evenly distributed.In addition,when the bath ratio is 1:1000,the kinetic constant k of MnO2-ZIF-8-SiO2 porous nanofiber material is 1.72×10-1 h-1,and the degradation rate of formaldehyde can reach 72.2%,which indicates that the MnO2-ZIF-8-SiO2 porous nanofiber material loaded with ZIF-8 has better degra-dation performance to formaldehyde.关键词
