Embodiment 1

[0033] Such as figure 1 As shown, the preparation method of the magnetic biomass functional carbon fiber based on photo-Fenton catalysis of the present embodiment comprises the following steps:

[0034] 1. The waste paper is crushed mechanically and ultrasonically, and the crushed paper is put into a sodium hydroxide solution with a concentration of 5 mol / L to extract plant fibers by hydrothermal treatment at 160°C. The hydrothermal time is 24 hours, and the obtained fibrous solid matter is Filter, wash and dry to obtain waste paper fibers. In this step, in other embodiments, the sodium hydroxide solution may be other strong alkaline solutions with a concentration of 0.1-10 mol / L to achieve the same or similar technical effects.

[0035] 2. Put the pretreated waste paper fibers into a muffle furnace for high-temperature carbonization at a heating rate of 5°C / min, a carbonization temperature of 500°C, and a carbonization time of 2 hours to obtain carbonized fibers. In this st...

Description

technical field [0001] The invention relates to the field of carbon fiber materials, in particular to a magnetic biomass functional carbon fiber based on photo-Fenton catalysis and a preparation method and application thereof. Background technique [0002] Activated carbon fiber is widely used in environmental purification, catalyst carrier, electrode material, etc. Using carbon fiber as nano-titanium dioxide photocatalyst carrier to treat organic wastewater can not only exert the efficient adsorption synergistic effect of carbon fiber, effectively improve the photocatalytic degradation performance of titanium dioxide on organic pollutants, but also solve the immobilization and loss of nano-scale titanium dioxide. It is widely used in the treatment of organic pollutant wastewater. However, the photocatalysis of carbon fiber photocatalysts is limited by the light source and catalytic efficiency, and it is difficult to treat organic pollutant wastewater efficiently on a large...
