Title:
IRON-NICKEL MOF/POLYACRYLONITRILE NANOFIBER MEMBRANE COMPOSITE CATHODE, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/231055
Kind Code:
A1
Abstract:
A preparation method for a stainless-steel-mesh-coated iron-nickel MOF/polyacrylonitrile nanofiber membrane composite cathode and the use thereof in promoting the removal of organic matter from pig farm wastewater. The preparation method therefor comprises: the synthesis of Fe/Ni-NH2BDC; the preparation of an MOF/polyacrylonitrile mixed nanofiber membrane; and the preparation of a stainless-steel-mesh-coated electrostatically-spun membrane composite electrode. The composite electrode can effectively promote the efficient degradation of COD in an electrically enhanced anaerobic digestion process, and can shorten the time of the anaerobic digestion reaction process and improve the treatment efficiency. In addition, the electrode has good stability and conductivity and relatively low cost, and has good application prospects in the aspect of efficiently removing COD in aquaculture sewage.
