|1. (WO2018205539) THREE-DIMENSIONAL LIGNIN POROUS CARBON/ZINC OXIDE COMPOSITE MATERIAL, PREPARATION THEREOF AND USE THEREOF IN FIELD OF PHOTOCATALYSIS|
|Applicants:||SOUTH CHINA UNIVERSITY OF TECHNOLOGY
|Title:||THREE-DIMENSIONAL LIGNIN POROUS CARBON/ZINC OXIDE COMPOSITE MATERIAL, PREPARATION THEREOF AND USE THEREOF IN FIELD OF PHOTOCATALYSIS|
Disclosed are a three-dimensional lignin porous carbon/zinc oxide composite material, the preparation thereof and the use thereof in the field of photocatalysis. The three-dimensional lignin porous carbon/zinc oxide composite material is prepared by means of: a first step of preparing a precursor composite of lignin and zinc oxide from a zinc salt, a weak-base salt and technical lignin by means of a hydrothermal method; and a second step of calcining the precursor composite of lignin and zinc oxide at a high temperature. The composite material has a three-dimensional porous structure, wherein the structure thereof is regular, and zinc oxide nanoparticles are evenly embedded between three-dimensional lignin porous carbon nanosheets. After same is applied to the field of photocatalysis, in particular serving as a photocatalyst for the photocatalytic degradation of organic dye contaminants, the degradation efficiency and degradation rate can be significantly improved, so that same has a potential application value in the field of the photocatalytic degradation of organic contaminants.
