Title:
METHOD FOR PREPARING LIGNIN-REDUCED CARBON NITRIDE MODIFIED BY NANO GOLD PARTICLE FOR EFFICIENTLY TREATING ORGANIC POLLUTION
Document Type and Number:
WIPO Patent Application WO/2019/019866
Kind Code:
A1
Abstract:
Disclosed is a method for preparing lignin-reduced carbon nitride modified by nano gold particles for efficiently treating organic pollution, the method involving first calcinating a precursor in a muffle furnace at a high temperature to prepare a semiconductor carbon nitride powder; then preparing the content of lignin according to a certain ratio, mixing same with the carbon nitride powder under acidic conditions, and adding a noble metal salt and reacting same for a period of time under water bath conditions; subjecting same to centrifugation and vacuum drying processing; and finally placing the dried powder in the muffle furnace for secondary calcination. The method not only has a simple process, low energy costs, and low raw material costs, but also has an outstanding effect with regard to the treatment of organic pollutants.
